In the previous video, we walked through an example of configuring OSPF for IPv
6 using
the traditional method to do that.
In this video, I'd like to share with you yet another option for configuring OS
PF, but
this time using a feature called OSPF V3 that supports address families that we
can
use with either IPv4 or IPv6 or bull.
So to do this, I do want to clear out any routing protocols that I've currently
configured,
so I'm going to go ahead and in the notepad document here, I have a little WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
so I'm going to go ahead and in the notepad document here, I have a little
section that
will allow you to clear off any dynamic routing protocols.
So let me go add to this thing, show and show IPv6 protocol, just to make sure
we've
cleaned it all up.
All right, so I'm going to go ahead and take that.
It just removes any routing that we've done so far, right click, copy.
Then I'm going to click on this icon right here.
So what this is going to do, it allows us to go ahead and put what we want to
send
out to our routers, and then we can send it out to multiple routers at the same
time.
So I'm going to right click and paste that in, and then I'm going to select all WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So I'm going to right click and paste that in, and then I'm going to select all
, select
all my devices, except I don't want to send this to my virtual PCs because they
have
no clue what this commands mean.
And then we'll go ahead and let me actually add a little couple of spaces there
, and then
we'll send it.
All right, so anything we configured in the previous videos as far as routing
goes is
done. And for IPv4 show IP protocol, no dynamic routing protocols running, and
then for
IPv6, no dynamic routing protocols running.
Fantastic.
So this gives us an opportunity now to configure OSPF version three using the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So this gives us an opportunity now to configure OSPF version three using the
OSPF V3 option.
So here's the syntax to make it happen.
We go into configuration mode, we're going to type in router, instead of IPv6
router OSPF
V3, and then the process ID of one in this example.
I'm going to once again set the auto cost reference bandwidth.
And behind the scenes, what it's actually doing, it's setting up address
families for IPv4
and IPv6 to support one or both of those protocols running OSPF. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and IPv6 to support one or both of those protocols running OSPF.
So then I'm going to go into each interface, and I'm going to enable OSPF on
each of the
interfaces for both IPv4 and IPv6.
So here's an example of doing that.
We're going to interface gig 0, 0 on R1, we'll say OSPF V3, 1, that's the
process ID1,
IPv4, assign it to area 0, that interface.
And the same thing for IPv6, using the keyword IPv6 instead, and we'll repeat
that process.
And then as we go down to another example here, here is R3, and now R3 is in WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And then as we go down to another example here, here is R3, and now R3 is in
two areas.
It's got two interfaces in area 0, and it's going to have one interface in area
1.
So the syntax is almost identical, it's just specifying a different area.
So what I like to do is go ahead and put these in on the routers.
Now as far as the syntax, you don't need to worry about that right now too much
because
in a separate skill, we're going to walk through the configuration and
manipulation of
OSPF V3 specifically.
So I'll have more practice then as well.
But I want to make you aware that this is an option.
So I'm going to right click, copy that, go to R1, and paste it in, and then I'm WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So I'm going to right click, copy that, go to R1, and paste it in, and then I'm
assuming
you're going to follow that process for the other routers.
So here's R2, we'll grab that, paste that in, and then something going to
repeat that for
each of the eight routers.
All right, so I put all eight of those configurations in.
Let's go to R4 and do a quick spot check.
So here on R4, which is an area border router between area 0 and area 2 for
both IPv4 and
IPv6.
One of the interesting things I've discovered is that if you do a show IP OSPF
Interface
Brief, it says nope, nothing. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Brief, it says nope, nothing.
So IPv6, OSPF Interface Brief, press enter, that shows the IPv6 portion.
However, the commands we'd want to use for consistent results if we're running
OSPF B3
specifically like we just configured, the best commands to use would be show OS
PF V3,
space, question mark, and check it out.
So no, because they interface, I'm going to go ahead and say brief.
And that's going to show us the output from an OSPF V3 perspective for both
address
families, IPv4 and IPv6.
So for IPv4, this interface has a cost of 15,625 and for IPv6 has the same cost WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So for IPv4, this interface has a cost of 15,625 and for IPv6 has the same cost
.
Here I'm fast to the net for a slash one.
It's the DR for IPv4.
It also happens to be the DR for IPv6 as well.
We'll go to show OSPF V3 and that will show us the router ID.
So here showing us the address family for IPv4 and the interface is involved
and the area
is involved.
We'll go down further.
Okay, then go ahead and show us the address family for IPv6 and its details as
well.
Also if we did a show run, pipe and section router, press enter, check it out. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Also if we did a show run, pipe and section router, press enter, check it out.
We also have separate sections under the OSPF V3 specifically for IPv4 unicast
and IPv6
unicast.
And then to test our full connectivity, let's bring back our topology from our
eight.
If we go ahead and ping the IPv4 address off our seven like 10.1.7.
or its equivalent IPv6 address which would be 2001, DB867837 colon colon seven.
It should show us the path and full connectivity across our network for both WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
It should show us the path and full connectivity across our network for both
protocols.
So let's go over to our seven.
Let's do a show IP interface brief and also to show IPv6 interface brief.
And that way I can just copy the addresses rather than having to go ahead and
type them
out manually.
So for IPv4, the address on the far bottom left of our topology is 10177.
So I'll go ahead and copy that with our eight.
Let's do a trace and we'll paste in that IPv4 address.
That's going to our six to our four.
And that's based on these last octets here. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And that's based on these last octets here.
Then to two, then one, then three, then five, then seven, fantastic.
Let's go back to our seven and this grab its IPv6 address off of its gig zero
zero interface.
Which is this one right here.
I'll copy that.
We'll go back to our eight and let's go ahead and do a trace and we'll trace to
that
IPv6 address, press enter and once again, following the same path.
And based on this last octet here is going up to our six and then our four and
our two
and our one, our three, our five and finally hits our seven. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and our one, our three, our five and finally hits our seven.
And primarily, I wanted to show you this video with OSPF V3 respectively
because I just
wanted to be aware that this option exists.
And in the next skill, we'll focus more of our attention on OSPF V3 with the
two address
families and do additional features with it.
And if you're ready for some hands on practice, join me in the next video.
I'd like to present for you a hands on lab that you can use to get that hands
on practice.
