media contact that’s given on the screen alright so what are we going to look at
today today we would be looking at 2.6 No yeah in the last video we did 2.6 we
introduced you to eigrp but this video we’ll look at configure and verification
so like I mentioned we’re going to look at two things configuration and
verification configuring AI GRP is very very simple like every other routing
protocol that we looked at rip and OSPF it’s very easy you go to the global
configuration mode and you say router ew GRP
now in in other cases we did OSPF for OSPF or rip for reproach in this case
it’s a IG RP so we say ow t IG RP and this is a global
configuration command so global configuration command router ew GRP and
then you give a autonomous system number so this number has to match let’s say if
you have fire outers and if you want all these fire routers to have AI GRP
protocols working in between each other and if you want them to be neighbors
then you need to have the same autonomous system number in in OSPF that
was a process ID process number but here it’s a autonomous system number in OSPF
this number need not match if you say route OSPF one that need not match if
you want to have neighbors write in AI GRP this number has to match with your
neighbor only then the neighbor ship would form so there are two ways of
giving the network command so like every rotten protocol once you do the ERG up
you go inside and then you need to introduce the networks which you want to
advertise right so this in once you are in the sub command there were two ways
that you can do one you could do without the wildcard mask so if you say network
and you say ten dot you could I mean when you do network without wildcard
mask you would just give a classful IP address where you should technically
give it which means it was it is going to take any IP at any interface
rather in in that router any interface starting with 10 it would add to ERP
routing that’s what this does this takes the entire class a Network now
even if you were to say 10 dot without the white card bus if you say
you do this eh RP will accept that command but it would automatically
convert it to so you might be entering your subnet network right
network ID of a subnet good thinking that it will accept it no it will access
the come you will not know its it has not
accepted the submit in fact what it has done is it has converted it to a class
full ten dot class a network and it’s converted it into 10.00 so it depends on
your first octet if it is ten it’s gonna be class if you’re giving a Class B IP
address it’s going to move it to a Class B Network and if it’s a Class C IP
address that you’re giving it is gonna move to the whole class c network so
that’s one way with all the wildcard mask but if you want to create the
subnet no if you want to give a certain subnet then you would use wildcard
massroots a network and you say ten dot one dot two well dot zero and you want
the slash 24 of this right so what you would do is not / but if you would give
this wildcard mask so you’re gonna give two five five
so ten network 0.255 is nothing but 10 dot one dot 12.0
/fauxbold true the wildcard mask format so you could
configure aig help in two-way one without this wildcard mask which would
take the entire classful network or if you want the translates network then you
need to give a wildcard mask so that’s the configuration bit so let’s go into
packet tracer and look at this topology this topology is what we learnt which we
in our introduction to feasible distance and reported distance in the the last
video we use this topology so we’re gonna use this we’re going to configure
this network in packet tracer and see how it works all right so this is the
topology and we have five routers router one router to router three rota four out
of five and we have the same i have configured the same even though they all
gigabit ethernet links i have gone and chained the bandwidth and delay to match
our topology so depending on this topology I have
configured packet tracer and have changed the bandwidth and delay
information to match this and on r5 in this network what I’ve done is I’ve put
a loopback interface and loopback interface I have given this IP address
have given the IPS to this interface and I have said this bandwidth
and delay information to match this right so let’s let’s go back to Patricia
right so how do we enable VI GRP so let’s go back here that’s going to at
the moment it’s only I have not any I’ve not enabled
yeah GRP I’ve just put the interface IP addresses right so let’s go in here so
let’s go to configure terminal right and I’m gonna enable ERP so I say router
EW GRP and I can put an autonomous system number so I can put any number
from 1 to 65535 so let’s do 1 hit enter now here like I said I can use to where
I can say Network and I can give an IP address right so if this one if you look
at the IP address here 10.1 or 12.0 10.1 or 13.0 10.1 at 14.0 right all of them
are in the 10 network so I could give one command I can say and it
says either I can put a while cut mask or I can hit enter right so if I hit
enter ERG RP is now going to run on all three
interfaces so all these three interfaces ERP would
run how can I check that I can say do show IP e IG RP interfaces okay and it
is going to tell me that ERG RP is running on these three to face a Gigabit Ethernet
0/0 Gigabit Ethernet 0 / 1 + C relay interface 0 / C so this is so I will
type that here again so that is show IP ERG on the interfaces and if I hit enter
this is one of the verification command to check which other interfaces ERG RP
is running on so ARP is running on those three interfaces which is fantastic now
let’s go here in router 2 let’s enable ERP and rotor 2 as well so configure
terminal router ERG RP 1 now this time we will not do the full network commands
we will try to give only the with the wild card with a white card mass will
it’s a network 10 dot one dot dot 0 0 dot 0 dot 0 dot 2 5 5
ok so now let’s do the same thing do show IP e IG RP interface and we see ERP
is running only on Gigabit Ethernet 0 / 0 because that only that interface
matched this command right it checked this command it said wildcard mask of 0
0 0 / 0 0 dot 0 dot 0 that means the first three octave needs to match so it
looks at all the interfaces where the firstly updates as are 10 dot one dot
any defense has 10.1 or 12 it puts that into a eigrp that’s what happened here
now let’s do the other thing 10.1 dot dot 0 chant entry 10.12 20 find out 0
and hit enter if we can do the verification again and we see AI g RP
Gigabit Ethernet 0 / 1 is also now part of the HRP you see Gigabit Ethernet 0/0
has already of one peer so one of the period that means one neighbor it has
found a neighbor and that neighbor is our one which we
already configured we look at some verification command later in this video
but for now we will go on configuring er GRP so let’s go here we could do any of
those with a wildcard mask or without wildcard mask to make it easy I’m gonna
make it without wildcard mask so router er GRP one network and that’s
it I’m gonna go back here I’m gonna do the same thing and to the terminal can’t
fake good terminal router a IGRT one network brilliant see how easy
idea is no compared to OSPF in always be if there are so many things that you
need to consider you need to look at ABR’s you need to consider if you have
multiple areas where you should which is the ideal location which should be the
ABR router and all that information you need to worry about erp is
straightforward you don’t really have to think about it so i can come in here
configure terminal router ai gr p 1e g r t1 network
and EIGRP is now running on all the devices let’s look at some of the
information so i go here i say show IP interface sure IP route okay when I say
show IP route let’s look at this interpret this I this interface or this
network neither etwork that’s the network that we were calculating in
the last video so let’s look at that so it says the network is T 4 and
the admin distance is 90 ya ARP has an admin sister distance of 90
d is EHR be sure whenever you see D that means it’s learned on ERP and this is
the metric so it says to go to this network 10.1 1.0 the network is the
metric is 2 6 1 1 2 so if you go back here it had to be 2 6 1 1 2 but it is 2
8 4 1 6 so I have to go back and see what happened
alright so we are in route of 5 so let’s do this let’s look at the show it sure
interface loop back 0 and let’s see what is it because it’s a loopback interface
idea so this is the thing the loopback interface here it is 10 milli sick 10
micro second according to our calculation but if you look at here our
delay is 5000 Milly’s microsecond now look at this whatever this what I was
talking about micro second so the you second is nothing but microsecond so
let’s do this let me see if I can change this configure terminal
I think loopback you can’t change but I’m gonna quickly check interface
loopback zero delay ok now this is another thing so that was microsecond to
free if you hit here it says throughput delay in tens of microseconds tens of
microseconds so whatever value you put here in microsecond it is going to be 10
times of it so if I say 1 delay 1 it is technically I don’t refer look back to
accept that delay if they do it’s going to be 10 microseconds so this is not
accepting but let me see if it’s accepting in calculation okay so it’s
not accepting even in calculation so if you do the calculation you will see that
the if you do the calculation with what we did in our last video you will see
that the calculation would take it to 2 6 1 1 2 that will be the calculation for
feasible distance from router 2 to this network so similarly we will
look at other figure the values so in rod 1 let’s do a show IP route and we
see the same thing we see there’s because the calculation has changed so
now technically everything is different it’s not gonna match with 2/6
I made 39 7-6 because their calculations matching but you you big you know how it
is done so what you could do is now you could start looking at your calculation
use use the formula that we gave in the last video try to match this figures
according to your packet trace if you have packet tracer look at all the
figures all the delay and bandwidth in each of those links in between create
your own topology and try to calculate but I mean if you ask me calculating is
not required just for you to know how it is calculated in your real lives you’re
never going to do this calculation you’re just gonna take that figure but
you need to know how it’s calculated so you know if you want to have let’s say
you’re doing load balancing which we will be discussing in a while in this
video you need to know how to change your delay you will never be changing
the bandwidth in real life bandwidth is something that you will not touch if you
want to fine tune eigrp most probably delay is the value that you would be
changing or tuning a little bit to get a certain value that you want right so you
could change bandwidth or delay and you could change the calculation amantha
metric so do that that’s going to be your homework and like always the
topology that we are going to use in factories today we will be using two
topologies both of them would be on our website before you by the time you watch
this so that’s something that you need to keep in mind so let’s go back to our presentation so so this is the Trapasso
basically enabling HRT is very simple very straightforward router AI GRP and
you put an ace number then you have two ways of
saying networks you say network without your wildcard mask or network with
wildcard mask and put of them would enable di GRP like in OSPF we have three
tables in EIGRP you have at the neighbor table then you have to polish a table
and the routing table we looked at the routing table let’s look at all three
once again all right so this is router ones CLI so let’s say let’s start with
neighbor table show IP e IG R P neighbor we see it has three neighbors ten dot
one dot – l dot – that is router – out of three ten dot one dot
14.4 that’s router for it also tells you through which interfaces the local
interface through which interface it reaches the neighbor
so it’s gigabit ethernet 0/0 it reaches the neighbor gigabit ethernet 0/1 it
reaches the neighbor and gigabit a serial interface 0/3 dorsal 3/0 and
through that interface it reaches the neighbors this is the whole time now if
you remember by default the whole time and hello time so hello time is five
seconds every five seconds there’s a hello that year joke is sense its
neighbor and the whole time is three times the hello times that’s 15 so
technically this value will keep going from 15 to 10 and every time every five
seconds when it reaches ten you would have a new hello message come and it
will reset to 15 so you see it will still go to 12 11 and it goes back 14
you see this right from 11 it went to 10 and then it reset to 40 so every five
second they’ll be a hello message and it will reset to 15 so this is the whole
time and it tells you up time so this is uptime again how many minutes since this
router has gone up and these are informations from if you remember our
RTP like reliable transmission protocol i say di japatalk stood neighbor using
RTP so RTP is these are informations relating to RTP
the next table that we’re going to look at is the hall
Jabil so show IP erp topology now topology table is very the entire
topology now if you look at topology from OSPF perspective OSPF had a very
in-depth apology it it literally knew the entire topology right it knew about
all the routers and all the links about all the routers so it made a very
comprehensive topology on that they had erp when you talk about topology it
doesn’t really look at the entire topology it with whatever metrics with
whatever updates ERP sense or the neighbor sends it it it does its
calculation and with with the calculation that it did like we know how
we do the calculation right using the calculation it takes it thinks about two
metrics so it looks at feasible distance it calculates its feasible distance and
whichever is got the lowest feasible distance right that becomes the route
that becomes a preferred route okay so in this case the two six three six eight
is the lowest FD and it takes that information to six three six eight and
it puts it in the routing table so two two six three six eight is the routing
table so if you look at the routing table which will look in a while you
will see that this is the preferred route Gigabit Ethernet 0/0 but we know
there is a feasible successor so this becomes a successor so that’s what the
successor will go into the routing table then depending on a condition the
condition is if the reported distance of the other one of I mean one becomes the
lowest the route with the low as ft becomes a successor whatever remaining
routes that you have it looks at the reported distance of all those routes
and if the reported distance is less than the feasible distance which is in
this case it’s true 3:07 too high
as a feasible distance less than rather reported distance less than the
freezable distance of 26,000 368 and hence that becomes the feasible
successor so that means if this link fails that is the Gigabit Ethernet 0/0
link ever fails for whatever reason this fellow would immediately become it
immediately becomes the successive so convergence in ERG RP is instantaneous
in OSPF they still have to do they they have the topology it needs to still run
this palca rhythm it does the SP fails algorithm even though it takes about one
or two seconds it still had to do that a calculation I
take some time depending on the topology it could take much more longer but in AI
GRP it doesn’t matter it’s instantaneous because it knows the backup right so
that’s topology now let’s look at the routing table show IP route so if you
look at that link we said it’s going to put this as because it’s got the lowest
FD it’s going to be the successor and the successor goes into the rhotic
tables that is the link that has gone to the routing table so routing table has
one link with a metric of two six three eight two six three eight is the FD and
that’s the lowest FD and that’s the successor so these are the three
topology tables rather they three tables of AIG are P so we chose if you okay now
once we have eh at the configured or if you’re coming to troubleshoot and you
want to see which are the interfaces EIGRP is running there are three
commands through which you can check the first is show running config obviously
that is something that we all know so I say sure run and then I can look at the
command for a router so it says router eigrp 1 and network 10 dot 0 dot 0 this
information I will not know which are the interfaces ERP is running on because
it just says network tender 0.0 to that interface I need to go and look
at all the interfaces interface Gigabit Ethernet 0/0 it is starting with 10
because this is classful so anything starting with 10 will be accepted this
is a degree 10 is accepted the starting with 10 it’s accepted and this is also
starting at 10 it’s accepted so all these three interfaces will be doing AI
GRP so that’s how you do you check with routing show running config the next
command is show IP protocols so I say show IP protocols and I can see that
routing protocol is ERP 1 and it says it’s s 1 it talks about metrics like I
said K values will not be touching K values because it’s not part of KCC MA
and by default we leave whatever is default I said K 1 and K 3 are ones that
means it’s only going to take these so don’t worry about that the router ID
just like OSPF router ID EA GRP also has router ID and it uses the same it looks
at configured router ID so if you go into HR p and if you’re telling a
certain router ID that is good to be the router ID if you don’t have a manually
configure router ID then it’s going to look at the load back interface the
highest loopback interface becomes a route ID if not highest IP version 4
router interfaces with high which has the highest IP address that IP address
becomes the route ID so the route ID is available here
automatic summarization is disabled now this is also important now summarization
is I mean in today’s world with because we don’t we do subnet because of subnet
because of classless routing we don’t look at summarization and it’s best
leave summarization off but if you if you enable summarization if you say Auto
summarization is enable what it is going to do is it’s going to summer ranks
every time let’s for instance let’s say let’s say you have a router here okay
you have a router here and let’s say this has three networks you have ten dot
1.2.0 ten dot one dot ten dot zero ten dot 1.5.0 right you have all these
networks here if and let’s say they’re doing ERP if you enable auto
summarization when this network sends an updated since ERP updated says it has a
route to 10.10 dot dot it tells that anything for dot
0 dot 0 / 8 send me updates row so any traffic coming to 10.1000
/ 8 traffic would come to this router so let’s say this is a router 1 and this is
router 2 it would say that anything any traffic that he wants to go to any 10
dot network send it to me you know in this case that’s fine but what happens
if there is another network here and you have 10 dot 1.5.0 here 10 dot one dot
dot 0 here now what happens and if even him I mean if let’s say this guy also
has the same thing it says Auto somebody he’s on he’s also going to tell the same
thing to this router 1 know this is a router 3 so router 3 is going to tell
her out of one that / 8 is available with me now this happens
because let’s say for instance if this is 192 192 168 1 dot 0 network
this is 192 168 2.0 Network so when this router it sees that ok now it is no more
10 I am going from 10 dot network to a one ninety two dot network so it says ok
knee to summarize at this level so this is a
decision er GRP makes whenever it goes to a non I mean if it’s going to a
different network so if it’s not if it’s it’s gonna work in classful and sees
that this is a class full network and ten dot anything that is not then it’s
going to something called 192 so I’m gonna summarize it now this is wrong so
if you could solve this problem by making sure that if you want to enable
summarization then you should make sure that all the things are gonna be here
right you can’t have tens anywhere else so you can’t have a non-contagious
network you have to make sure as an administrator from by your design you
should design in such a way that all your tens network or rather that entire
class full IP address range network is going to be in the same router then yes
summarization will work in today’s well the best thing is just to say Auto
summarization is not enabled so if you say visible what it would do is instead
of sending this one update it would say ten dot one dot two dots zeroes slash 24
is here then it would send one network for this one update for this and one
update for this it will send three separate update slash twenty fours and
that way the routing table are one sorting table would be slightly more
populated because instead of having one route it would have three routes and
depending on the number of routes it will have more routes
if summarization is not enabled so summarization would help it reduce the
number of routing entries in the routing table but if you don’t plan it well you
could destroy your network so that’s running config you could do show IP
protocol so let’s go back to show protocols so summarization is disabled
one of the things so this is the distance by default the distance is 90
like I said the admin distance is 90 maximum part is 4 by default max maximum
path is for load balancing so if up to 4 load equal costs like if you have equal
cause if the metrics are equal up for links can become load-balancing
where it will start sending traffic by balancing the load Ossipee falls who
could do that right so if you want to change by default it is for if you want
to change it to you say only two up to two links I want it to be load balancing
you can go to maximum path and then change that value to two right that’s
something that you could do maximum hop count if you remember drip maximum Conn
was 16 here Maxima count is 1200 variants again if you want to do an
equal a cost load balancing you need to make use of this figure variance we’ll
talk about it when you’re talking about load balancing a while later routing for
network is 10 dot 0 dot 0 this is another way for you to understand how
this is configured so when a is routing for networks it is nothing but
we have used the non wildcard version so if it’s a wild-card version it’s going
to show those individually here we look at in router 2 because we did router 2
with wildcard so we’ll look at that we’ll do that right away so let’s do the
same thing here show show IP protocols and we see that rotting for networks
because we use wildcard it says ten dot one dot dot 0 slash 24 10 dot one dot
dot 0 slash 24 now the reason I want you to do all these things is in your in
your real life it’s easy you could just type out all these commands and check
but in your exam you might only have an output shown for show IT protocols and
then you need to know how to look at this information and find out what has
happened right so it’s best to take no elected take a notebook and start
writing the information so you can type this command and see what are the
information available in this command when you say show IP topology show IP
eigrp topology what are the data that’s available so as a if you want to master
Cisco maybe not so much for CCNA but if you
want to go ahead in Cisco maybe CCNP CCIE it’s best to know what is there
right each it’s basically your Cisco’s for a
certification program is your mastery on your CL ax right mastering iOS devices
that’s maybe about 75% 80% of your CCNA ccnp CCI tests and your knowledge is
knowledge about Cisco’s CLI of course the technology knowing how these
technology work and all that is also important but more important is Cisco
IOS how can you configure Cisco devices to a certain format right so you need to
know what are the information Cisco’s commands right IO is what command gives
you what information that is something that you’ll need to master so let’s go
back here so then it talks about routing information so right routing information
source it tells you the IP address of those devices in if you remember of OSPF
OSPF spoke about the router ID of those devices here it’s not talking about the
router ID it’s timed out it’s not talking about router IDs it’s talking
about the IP address of those devices so the other way to look at so to verify
ERG IP interface is something that we already did but we’ll do it again and
that is by typing show IP eigrp interface so show IP e IG RP interface
and we see these three interfaces are working ami HRP right so this is how
these are three ways with which you can verify if ERG RP is working on an
interface next we look at load balancing like I said so if two interfaces have
equal cost by default load balancing so what it would do okay let’s let’s take
take a packet physics all right so this is the topology we’re
gonna work on mmm like I said this is configured and it’s all the bandwidth
the bandwidth and delay is same for all the four links so let’s enable er GRP in
all these devices and we know how to enable a jarppi configure terminal
router aig rp1 network 10.000 okay i’m gonna quickly show run I mean sheet of
it so I can do this I can say copy and I can go here see ally anybody terminal
and then paste this typing the whole but I can say paste enter paste enter okay
now since the cost now we’re looking at reaching this interface the loopback
interface from r1 and since this has the same bandwidth and delay for all the
foldings it should have equal cost to reach to buidling so let’s say show IP
route and we would see that okay right so we see that it’s learned through
eigrp there are two links so you can go through Gigabit Ethernet 0
slash 0 and Gigabit Ethernet 0 / 1 both of them have the same metric so this is
equal cost we could look at the topology as well show IP e IG RP topology and we
see the same information here two successes they both have this Amin of
course this is the FB so that’s why both of them have the same FD
and that’s why you have two successes now we knew that equal cause
load-balancing do you know what it is because even a IG even OSPF did it so
OSPF did it as long as the cost the same you do equal cost load balancing but
with OSPF calculating costs and it’s its most straightforward there was not much
that would change but that’s not how EA GRP is now if you see some of the
calculations some of the metric calculation CI GRP went into the
millions right so you would have EHR p1 network with two million two hundred
twenty five thousand two hundred and there would be another cost which was
two hundred and one right maybe one you know if you talking about in millions
the difference between the two would have been just like one right both of
them are really bad connection but you could technically make use of load
balancing you know two bad connections as good as one no better connection
right with load balancing so yeah job gives you a way through
which you can edit right you could fine tune erp to consider two unequal cost
lines or unequal constant links to still be considered for load balancing now how
do you do that we use something called as variance right so let’s take smaller
values so I’m going to take smaller f DS and our DS and let’s say there is one
router and these are the four routes considering FD router two is the
successor yeah we know why it is because 90 is the FBM that 90 is the least among
the three right so 90 is the FD now consider the Rd of the other two links
so is all dat less than 90 yes so this is a potential candidate for feasible
successor okay and 180 is not less than 90 so
this will never be a feasible successor so now we have success and feasible
successor now load balancing unequal low annual unequal cost load balancing is
you have a feasible successor now at what condition right at certain if you
tune it certain way you can take use of the feasible successor into your routing
table and do an equal cost load balancing so do we use a variance call
views of parameter called variance so you go into ERP and you say variance –
so by default variance is 1 but when you say variance – what it does is it looks
at the successors FD multiplies by the variant so in this case it is 90 so if
you do variance – right at the rate of variance – this becomes 180 now if the
other FD right if your feasible successors FD is less than 180 then it
will go to the routing table so in the first case if it’s variance 1 this it
will not go into the routing table only this will go to the routing table this
will never go to the routing table in any case because it is not even a
feasible successor but if this one you look at variance to the FD is less than
180 so this will go into the routing table FD this will obviously go to the
routing table now when you go to variance 3 at variance 3 this is 270
right anything less than 270 will go to the routing table so 120 is less than
route 270 this will go but don’t get confused see again that’s the reason I
put X math in the beginning even though 250 is a less than 270 we would if you
don’t think properly you would think it’s 250 is less than 270 it should go
into a routing table with variance 3 no it will not go because this condition
does much right the reported distance is not
less than 90 so this will not be a feasible successor so because it’s not a
feasible successor even with variance 3 it is not going to get in the routing
table right so this is how you enable no one I mean not equal cost links right
any unequal cost links we would shade the variance values and make sure that
they go into the routing table so that’s how you do variable cost or rather
unequal cause load balancing with the engine P this is something that’s not
there in OSPF it’s supported by a idea so thank you so much for watching don’t
forget to hit that like button if you liked this video and of course subscribe
to this channel to get more videos thank you so much we will be coming back very
very soon with more videos so until then stay tuned and see all very very soon
