It's time for hands-on practice if you'd like it,
with EIGRP stub routing.
[MUSIC PLAYING]
So here's the play-by-play if you
want to get the hands-on practice with EIGRP stub
routing.
If you're logged onto the CBT Nuggets website,
click on the link associated with this video
for the virtual lab.
And this is the topology we're going to work with.
Now, EIGRP is already set up across the entire network
for both IPv4 and IPv6.
Now, the ability to configure stub routing WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Now, the ability to configure stub routing
is the same for IPv4 and IPv6.
You simply go to the address family for IPv4 or IPv6,
and you simply use the command EIGRP stub, and poof.
It's now a stub router for that autonomous system
within that address family.
So here's what I'd like you to do in the lab.
I would like you to configure both R7 and R8 as stubs.
I'd like you to advertise their connected routes, also.
And that's so you have full connectivity and reachability
for the network. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
for the network.
And if you're up for it, I'd like
you to do IPv4, that address family, and also IPv6.
And then the show commands are similar for the address
families, except for IPv4 or IPv6.
Or if you want to use the show IP versus show IPv6,
those commands still work as well.
So here's what I'll have you do.
Go ahead and pause the video right now.
Enjoy the lab.
Have a great time.
And when you're ready for me to do a walkthrough with you,
go ahead and click on Resume, and we'll
do the walkthrough together.
WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
All right, let's go ahead and tackle this together.
So let me start on R7.
In fact, let's start--
let's take a peek from R5's perspective, just
to verify that we have a neighborship with R7
and we see him as a normal neighbor, not a stub.
And then we'll go ahead and tweak R7 and look
at the differences as well.
All right.
So on R5, let's do a show ip eigrp neighbors.
We'll do a show ipv6 eigrp neighbors.
And if you want to do the address family WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And if you want to do the address family
flavor with EIGRP first and not the keyword IP or IPv6,
awesome.
Both commands work great.
All right, so we have--
oh, and I want details.
There we go.
That's going to show us the details, whether we have a stub
or not.
That's for IPv6.
And let's do the same one for IPv4.
Are we doing address family, or aren't you?
And this command is not.
So I'm just going to put ip, which means implied IPv4, press
Enter. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Enter.
All right, great.
So let's make R7 and R8 stubs for both IPv4 and IPv6.
So we'll do the show run pipe section router.
That'll save us a little bit of typing.
We'll then go into configuration mode.
And we will go in to address family for IPv4 first.
And then eigrp stub connected.
Just like that.
And then we'll go into address family for IPv6
and be like doing this.
Bump.
So address family for IPv6 and eigrp stub connected. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So address family for IPv6 and eigrp stub connected.
And then we repeat that process on R8.
So let's go ahead and do that.
In fact, let's see, I'm going to cheat a little bit.
Let's do a config t, do show history.
Because there's a separate history buffer
for the configuration commands.
Oh, look at that.
I might be able to use that.
Mm-hmm, mm-hmm, mm-hmm, mm-hmm.
That'll work.
So I just--
I laid it all out.
It's now copied to my buffer on this virtual machine. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
It's now copied to my buffer on this virtual machine.
We'll go to R8, go into configuration mode.
And Boom.
I love it.
All right.
Then we just go talk to a neighbor.
And we can go to R6.
Let me just take a look at our topology.
So R6 is a neighbor to R8.
And R5 is a neighbor to R7.
So on the left hand side is the odd-numbered routers.
On the right hand side is the even-numbered routers.
And we'll go back to R6.
We'll do a show ip eigrp neighbor detail. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
We'll do a show ip eigrp neighbor detail.
Sure enough, we're a stub for IPv4.
And we'll just slide in a IPv6.
And sure enough, it's a stub for IPv6 as well.
And we'll see about R5 with its neighborship with R7.
There's IPv4.
And there's IPv6.
And just for grins, let's do it with the address families,
just to remind ourselves that that's also an option.
Show eigrp address family IPv-- WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Show eigrp address family IPv--
let's go for 4 first.
And then neighbors detail.
All right, awesome.
And then we'll do the same thing for IPv6.
Same output, different commands.
One has less typing.
So thanks for joining me for this hands-on lab for a little
up close and personal work that you
can do to get hands-on practice with working with EIGRP stub
routing.
Now, there is one other option that's fairly new.
It came out with, like, iOS 15.5, I think, and higher. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
It came out with, like, iOS 15.5, I think, and higher.
And that is with stub sites.
And so what I'd like to do in the next video,
I'd like to introduce you to that option
as well so you're aware of it.
And that'll complete this set of videos regarding
stub routing with EIGRP.
So I'll see you in that next video in just a moment.
Meanwhile, I hope this has been informative for you,
and I'd like to thank you for viewing.
