In this video and hands on lab we're
going to two basic things.
Number one, I'm going to show you
the lay of the land for the IPv6 OSPF network,
and then secondly, give you a chance to the virtual lab
to go ahead and log on and get your feet wet and comfortable
with the topology.
[MUSIC PLAYING]
So let's start with some of the basics for this topology.
On the left hand side of the screen we've got our 1, our 3,
our 5, our 7.
On the right hand side of the screen
we've got our 2, our 4, our 6, and our 8. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
we've got our 2, our 4, our 6, and our 8.
And we have the adjacencies are between each
of the routers that are shown.
Now, for this specific lab and this set of labs,
we're not going to be using these two links between R3
and R8 and R7 and R8.
So we'll just go ahead and cross those out for the moment.
As far as IPv6 addressing, I'm using this scheme.
2001 DB8 6783.
And then RR.
That RR represents the two routers involved.
So if it's between R3 and R4, it'd
be network 34 in that space.
And if it's between R6 and R8 it would be 68 in that space. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And if it's between R6 and R8 it would be 68 in that space.
And off of gig 00 on a few of these routers like R1 is
the one network.
So that would be 2001 DB8 6783 1 colon, colon slash 64.
That would be that network.
And down here'd be 7.
And I've also got some PCs that you
can play with if you'd like.
They are sitting off these networks here,
and one over here at PC8.
And then the virtual lab, you can click on those devices.
And they have their IP addresses shown.
And you can use them if you want,
anyway you want as far as troubleshooting
and verification.
All right. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
All right.
So this is a fully functional network.
What I would like to do is walk you
through a few of my favorite commands.
And what I would encourage you to do
is click on the link for the virtual lab
if you're logged on to the CBT Nuggets website
and join me so you can get comfortable with where things
are, when we have a functioning network,
and some of my favorite show commands
regarding troubleshooting and working
with IPv6's flavor of OSPF.
So here in the virtual lab environment
I've got tabs for R1, 2, 3, 4, 5, 6, 7, 8.
And just remember that the odd routers, R1, R3, R5, R7 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And just remember that the odd routers, R1, R3, R5, R7
go down the left hand side of the topology,
and the even ones are on the right.
And in the diagram I also have shown
which networks are going to be included in which area.
So all the networks appear in this blue area zero.
And then in green, area one.
And over on the right, area two.
All right.
So going back to the CLI, some of the show
commands that we could issue, they're very much like the IPv4
show commands, except throw in the IPv6 every, every time.
So a show IPv6 OSPF interface brief. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So a show IPv6 OSPF interface brief.
That'll show you what interfaces are running OSPF
for version three for IPv6.
We could verify which IPv6 addresses
we have with show IPv6.
Interface brief.
Still hard sometimes to type in that IPv6.
And that'll show us the IPv6 addresses, both the link local
and the globally routable addresses.
Other commands would include show IPv6 OSPF all by itself.
And that'll show us the details for OSPF, the router WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And that'll show us the details for OSPF, the router
ID, the role of the router, also the areas it's involved with.
So this a backbone.
We have three interfaces on R1 in area 0,
which is the backbone.
If there was authentication that was required,
it would show here.
And hm, what else?
How about show IPv6 protocols.
That's another winner.
See what dynamic routing protocols we have for OSPF.
And this is showing us that we have area 0,
we have these three interfaces that are participating. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
we have these three interfaces that are participating.
We saw those earlier for the show IPv6 OSPF interface brief.
And how about show IPv6 OSPF neighbors?
And that shows us our neighbors and our adjacencies
if we have them.
This is R1, saying I have a full adjacency with R2.
And it is the DR, which would imply that we are on the gig 1
slash 0 interface.
Show IPv6 OSPF interface brief.
And gig 1 slash 0.
That would imply that we are the BDR if it's the DR WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
That would imply that we are the BDR if it's the DR
and there's only two of us here on that network segment.
So part of the secret, I would say,
to use if you can is to have the topology really,
really available.
So what I do is I just print a hard copy.
Or you can have the topology on a second screen,
or log onto the CBT Nuggets website with a tablet
and have the actual screen there.
That way you can see the topology
and actually have the CLI at the same time
and get familiar with the network.
Another test we could do, if we just
want to verify full connectivity from R7 all the way over WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
want to verify full connectivity from R7 all the way over
to R8 to this address, because IPv6 addresses are
kind of long, we could do this.
We could just go to R8 and do a show IPv6 interface brief.
And there is the gig 00 interface address right there,
2001 DB8.
So just highlight that.
It'll automatically copy to the buffer in PuTTY.
Go over to R7, which is on the left hand side of the network.
We'll do a trace.
And then we'll paste in that address.
And that will verify full connectivity WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And that will verify full connectivity
and the full path all the way through the network.
And the last number of the IPv6 address matches the router.
So this went from R7 to R5, to R3, to R1, R2,
to R4, to R6, to R8.
Fantastic.
So those are some of my favorite commands regarding IPv6.
So in the next video and lab, which will be a troubleshooting
lab, I'll introduce the problem, and turn
you loose on solving the problem regarding IPv6 and OSPF.
So I'll see you in that next video and lab.
Meanwhile, I hope this has been informative for you,
and I'd like to thank you for viewing. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
