- [Narrator] Alright, let's run out to the Corp router
and put some IPv6 addresses on the interfaces.
We have four interfaces on the Corp router.
S011 going to San Francisco.
S001 and S010 going to L.A.
And then we have our FA00
on the land of our Corp router.
Let's run out there and configure them
and just be aware that I've already configured
the San Francisco and L.A. routers
with their respective IPv6 addresses.
So also, I wanna mention one more thing
I'm on subnet six between Corporate and San Francisco
subnet seven and eight between Corp and L.A.
and subnet one on the Corp LAN.
Alright, the first thing we wanna do
is enable IPv6 routing.
If I was doing
IP Version 4 it's just
IP routing.
That's enabled by default.
But to do IPv6
it's IPv6 what?
Unicast-routing.
Now I can go out to my interfaces
say IPv6 address
and I'm gonna only have to type this in once 'cause
I know it seems cumbersome to you guys
but once you get used to it, it's really not that bad.
Alright subnet.
So there's my first four fields of 16 bits each.
Leading zeros are not necessary.
So that's zero zero zero one.
So I could have typed this as this.
That's fine.
And then colon colon.
I didn't have to put colon colon
but I'm saying it's all zeros now.
I could have just done colon and typed out
the next four fields for my host address.
First four fields are network.
The next four fields are host
but I'm gonna do colon colon two.
And the reason I did that is I did colon colon one
with subnet one on the San Francisco router.
Why don't I go ahead and put one in here.
So you can take a look and see what happens.
So I put one in here connecting to my San Fran
oh this is on my
sorry I could have done this, this is on my Corp LAN
so I don't have a connection here.
Anyways, let's go try that on the S010.
And watch how easy this is now.
Because I'm gonna up arrow
and then just change the subnet.
And I don't have to have a zero zero zero one here.
Okay and this is subnet six here.
So I can just do colon six zero.
The leading zeros are optional.
Notice I'm still using host ID, one, okay?
So this is my connection to San Francisco.
And it shouldn't come back and tell us like
"I'm not happy about this because you used colon colon one
"on the San Francisco side."
So it'll come back in a second and tell us so.
In the meantime, I'll leave that
as zero one
zero one.
This is my connection to L.A.
My first connection.
Up arrow.
Change this to subnet seven.
And then I have one at subnet eight off of S010.
Alright, so I have my four interfaces.
And now I'm gonna start getting my duplicates.
So you wanna be careful here because a lot of times
people use colon colon one to, just identify an interface
which is great.
But, if you have a router on the other side then
and you do the same thing, like I just did.
So this is saying zero zero one zero
so let's go out to, that's my last one I just did.
Now that's the interface that I'm on.
But I'm gonna just change this id to a two.
Because I did the other one as one.
Now I could have left this alone and done a
configure it in EY 64
and let it configure itself.
But in this case here I wanted to assign it.
Alright so that's how I can configure my four interfaces.
Now I didn't get an interface IP address configuration
duplicate on interface S011
and S001.
But so, I'm gonna go change them anyways.
We changed one zero.
Let's go ahead and change zero serial zero zero one.
And that's serial zero
zero one subnet seven.
So I'll make sure I do the right one.
And then make him a two.
Alright and then we've got interface S011.
Which is subnet six.
So I'm just gonna up arrow to this guy.
Notice I'm just making them all two.
Okay now, to verify this real quick
and wrap this up.
Show IP int brief, right?
So
that being said, let's do the same thing.
So IPv6 interface brief.
Okay?
So we can see our Fast Ethernet at zero zero.
Now, what's that FE80, I didn't assign that.
I have the 2001, I assigned that.
And that's my global address, DB83C4D subnet one.
Colon colon one.
That FE80 is my link-local, right?
My link-local.
That's equivalent to the IP address, in IP Version 4.
So let's come down here to Serial zero zero one.
And
the one thing I do need to tell you, which I didn't do
and I'm glad, this is why we do verification my friends.
When you put another IP address, on an interface
it replaces the other IP address
when you use an IP Version 4.
An IPv6, it doesn't do that because
I can only have one IP address on an interface.
However, I can have
as many IPv6 addresses as I want, and this shows that.
Let's take a look at one more command
before we get into the routing section.
Show IPv6.
Now there's a lot here if I did question mark.
But I wanna do interface
and we'll just pick an interface that we use and
take a look at the details that we see.
Okay, so this is kind of like doing
the show IP interface with IP Version 4.
Show IPv6 interface.
Fast Ethernet zero zero's up, line protocol's up
of course, we see
IPv6 is enabled, our link-local address
our Global unicast address showing our subnet.
Our multi-cast groups for FF02
is our router connections our routing.
And we see our MTU
and our Neighbor Discovery information at the bottom.
And one last command, if we just did a show run
and then take a look at our interface as well.
And we'll see that I still have
multiple IPv6 addresses on here
that I'm gonna have to get rid of.
But you can see that
with just a few commands
we can have IPv6 up and running
but we haven't done routing yet
so that's coming up next.
