00:04
Okay, so let's configure and you II p v six address on router one.
00:10
First, I'm going to check
00:14
Mac address on F 00 off rather one, which is right here,
00:20
and we should be familiar with this apology by now.
00:28
So as 00 of rather one has an address 00605 season zero Sierra one. The one I had on the board a few minutes ago.
00:38
I go into config moment for the router and enable I p v six routing
00:45
with the command i p v six Juni cast routing on the router.
00:51
Then I can go into the interface fastest in a 050 and I can say I p v six enable
01:02
this enables at p V six on the interface
01:06
and automatically creates
01:10
an I P V six link local address. Let's see what this link local address looks like. If I say do show i p v six interface grief,
01:22
it's the same command, but incentive. If I pee, I'm saying I p v six same command be used for I p v four.
01:29
You see this address? FDA zero Coghlan Coghlan 2605 c F f f ea 60 Sierra one.
01:37
We haven't created an e y address yet, but I p v six auto configures would we call link local addresses that always start with F E 80
01:49
Now, these addresses are used as next top I p addresses by layer three routing protocols like route information protocol E g R p and O S P. F.
02:04
let's create our I p v six you I address. So I believe our prefix was 2000.
02:16
and now I'm gonna assign it a prefix. 2002
02:21
colon zero colon zero colon 000 a
02:29
Flash 64 Space question mark and see, It gives me that US 64 option. And if I say
02:39
this inter financial auto assigned itself in you I 64 address by putting or inserting this Mac
02:50
address, I have zero size zero Mac address into this last 64 prefix.
02:57
Now let's look at our new show I p v six interface
03:06
and we see that the router came up with exactly the answer we got when we did this manually on the board, which is 2002 Colin Colin. A cool in 260 Cool in five cff Colin F ea 60 call in Sierra one.
03:23
However, you don't have to have I p v six Auto configure I p addresses for you because, God News,
03:30
Who is going to remember this with the Mac address inserted into the eye P V six address? So let's get rid of it.
03:38
I generally don't like these.
03:42
That's a sign and an I p address. Manually, we picked one,
03:49
I simply said I p v six
03:55
Then I can simply say Coghlan Coghlan
04:05
Let's make its last 64. Still,
04:08
this is rather one. So I said Colin, Colin one.
04:12
Let's go to Router to
04:15
and a sign of night BB six. Address
04:30
Coghlan. Coghlan too
04:38
Let's assigned to Thought so. Basically, this address is actually I. P V six. Well, I will expand it out for out or three.
04:47
So let's go to Round three
04:58
I N c f zero slide. Zero i p v six
05:04
Colin 0000 called 00000000 Cold and zeros here
05:12
0000 Colin 0000 Colon 0000 Let's see how many fields have one, too to be for
05:21
five. I want too many zeros here.
05:30
than colon 0003 slash 64.
05:34
So this is the prefects,
05:38
and this is the I. P. V six address host address or the load address palooka do show I P v six i nt brief. You see, it has been shortened to 2000 to Colin Colin. Three.
05:53
Let's do the same for route or four, and we can test this out a little bit.
06:04
interferes Facet in a 00 i p v six address 2000 to Colin Colin Force last 64.
06:15
Now can we pin between Router 123 and four? Well, let's find out.
06:24
iptv *** 2000 to Cole and Cole, and one
06:29
it works. 2000 to Colin Colin to Rocks 2002 Calling Cole and three. It works 2002 Colon calling for it Works
06:39
What if I wanted to ping that
06:46
link? Local address on Router one from Router four through I P v six interface Brief This F E 80 address and every router created this for itself.
07:00
What if I'm paying this address? What happens now?
07:09
and I try and pin this address
07:12
Now it says Outward interface.
07:15
Now my output interface on fat on
07:20
What happens if I type in at 00?
07:27
It says invalid interface, and I'm sitting here wondering what's going on. That's the correct interface.
07:32
Unfortunate thing. And I don't know why Cisco did this. You actually have to type in the whole interface name as in Fast
07:49
It's unfortunate that you have to type in the full interface i d. Once you do, it starts pinging
07:59
and rather for just to show you the I P V six interface,
08:07
the I P V six interface brief also created itself for itself a link local address as all routers, all devices will.
08:18
We're gonna break here for a second
08:22
and then continue without visas
