Hello and welcome back to I C ndy one interconnecting Cisco networking devices Part one. This is absolute 7 to 2. Implementing unit cast addresses on routers. I am certain there will be instructive for this course, unless what he always just went over the list of 7.2 overview and did a few pre assessment questions. Hope to get your brain thinking.
And in this episode, Or you could be covering howto add an I P. V six address to a rotter manually and also out of Let the Rotor created itself.
So first, we're gonna look at adding an I P V six address to an interface. We're going to enable HPV six routing or allow the enable the actual process to start. And then we'll look at you. I'd, uh, 64 dressing
a quick, pretty system here. What is the binary of the hex character? E?
Give me a few seconds.
All right. Hopefully you got letter C or 1110
so I would be six on routers. The way it's set up right now is we have dual stacking, which is saying that we're gonna run in both I pee before and I could be six protocols.
The reason why we do this is we You can't change the entire world to I p b six overnight. It's gonna be a
couple decade process, I think of converting everybody over to the I V six. So we had to have we had to be able to duel. Sacker. Use both protocols while we're transitioning and ivy. Six.
So ivy six. We still have manual addressing where we can. We can add a
just manual address to the interface, and we will do that here in the party session. Just a moment.
This can either be the full 32 hex character or 128 bit. Or you can use that shortened down version that we learned in the last lesson where you can use a double Coghlan's. You can remove the leading zeros, that kind of thing.
So our dynamic addressing options. We have the state fel de A. C P. That's just where you get the address from your D a. C p. Like normal. We have the stateless address, auto configuration or slack. What this does is it uses the router advertisements and router solicitation messages.
We'll learn more about it. And if you stick around for I Sandy, too. But just know that that is a way that the host will kind of look out on the network and send these messages saying, Hey, you know what? What is our global routing prefix? What is this information? And it will create an address
off that router. Advertisements that assume to it
if only what we want to do to actually enable the ability to have HPV six routing. We do the HPV six unit cast ash routing, global configuration command
and our interface options for show commands are basically the same. We just have a V six in front of after I pee. Now,
I'm gonna go ahead and bring up our party session on and we'll go ahead and throw a couple I P Address is on there.
if we just do a un risk yours show I p interface brief. Let's see, we got on there.
Okay, So So fuel's going figure terminal was going to f a 00
Here's where we wants the address.
So here is we have the prefix vehicle like local. So you quite a bit different news. I don't have the d c P server set up on.
We don't have any other ones that work with slack, so we're just gonna put in a full
All right, so now we have Ah, V six address on the interface has been manually signed here.
So we're gonna go in, and we're gonna enable the abilities for HPV six
someone along want to do a
You you I 64 someone do that on the I think that which serial interface do we have up right now? Should I be in its brief
cereals? Years there? Zero.
Hi. P V six address.
And here's where we're going to sit.
We're gonna go ahead and sit the link local that starts with E 80.
Okay, on, we'll just go down 01
we want to do interface, and we'll see what this shows us
hear phasers are automatically created its own like local.
And I'll show you how to do this. Here. This is the
you I 64 address portion.
She had a get in a minute and this was our statically assigned link local address. So if we run a show I p B six interface a phaser zero, we get a little more information.
Here we have our multi CASS address that we joined what you'll see in the next episode.
Lindros with E sub net or the Routing Prefects.
And here is our link Local address. This one was automatically created because every time you
enable HPV six on the address is going to automatically create that interface link local address.
So we're going to pull the party session down
and we will continue on. So if you look at doing the modified you I 64 address or sometimes just known as US 64 that is the extent of unique identify rhe with us. Actually doing is using the Mac address that is on the interface.
And what is going to Dio is
it's going to use that global rounding prefects for the sub net and everything else, and it's going t take the Mac address, which is 12. Hex Character's is going to split it in half, so we have six on each side
is going to place f f f e in between the two parts.
So now we have 16 total characters or we have four blocks. And once we have f f e in the middle, there were going to actually invert the seventh bit from the left.
So I'm gonna show you how we do that here. So if we take this address here and you remember, each
is four bets. Right? So the seventh bit is always going to be in this second letter here.
And remember, this is going to be 5678 This is just the bit placement.
So we're gonna go ahead and invert that seven's bit. Certainly. 1001 now,
which would be nine.
So you I was gonna say Aye.
f E. Summer. That's place in the middle. We gotta fall that HPV six address scheme
So I'm gonna go and do that with the next one here.
So if we take the second letter where the seventh is gonna be and we do eight
We're gonna flip this third or seventh pits.
So 1010 That gives us 10
Hopefully that makes sense to everyone.
so actually going to move into the next one? We're gonna do a bit off
practice with this, So go ahead and write these down. Pause it, see if you can figure out he's out.
All right? Hopefully you got all these. I'm gonna go ahead and start going here. So we have one.
And eight is going to be this. We're going to flip this bit. So 1010 That leaves us with 10
five. If we throw the f f e r f f f e in the middle
and we have F one colon
So if you got that right, we're gonna move on to the next one.
and F ISS the 11111101 will flip that last bit.
So you were 12. 13. So we have d 12 going
eight d and we throw the F f F E in the middle,
So we go on to this one here
and a is going to be 1010 Flip this bit. 1000 uses with eight
d e. We throw f f f e into the middle.
All right. Hopefully it made sense for you guys. Um, it didn't please go back.
Although I was gonna move in toothy recap here.
So first we went to the duel Staking purpose. We went. We know why
you got to remember that. We can't switch to MTV six overnight. We had to have both protocols enabled for this to work for us, for it to use it. During the transition period,
we went over adding a static address to the I p d six. We did the We let the link local address automatically create itself. Using that you I 64. I went over somebody interface show commands for I P V six and friendly. We had some practice with the you. I 64 addresses
so quick, Pull assessment here. We're gonna do a little more mats. So with this one, I have the interface, Mac. And then I had the prefix there.
Now, if you notice the prefix is the same for all of them, all it does is just add those 1st 4 blocks in there since it's a slash 64.
So I'm going to give you a few seconds here, see if you can figure out that last interface. Mac, address part for us 64.
All right, Hopefully you got a letter C.
We have the f f E in the middle. We went and flipped that seventh bit from D to nine,
and then we turn the rest.
So the next episode, we're gonna look at a few other leave router addresses that I p v six uses.
And as always, if you guys have questions, need help. Feel free to shoot the message. Otherwise, so you for watching this episode, and I look forward to seeing the rest of them
