1
00:00:01,000 --> 00:00:06,700
In this example, I've got three Cisco, iOS, AVI routers that have just put it up.

2
00:00:07,090 --> 00:00:09,390
One is going to act as our client.

3
00:00:09,430 --> 00:00:17,050
One's going to act as a DHCP version six relay agent and one is going to act as our DHCP version six

4
00:00:17,050 --> 00:00:17,830
server.

5
00:00:19,310 --> 00:00:21,530
So let's start with a relay agent.

6
00:00:22,220 --> 00:00:23,870
I'll call this Rado relay.

7
00:00:25,360 --> 00:00:30,100
And then on gigabit 00l no shut to the interface.

8
00:00:31,410 --> 00:00:37,560
And actually before configure IP version six addresses, let's configure IP version six unicast routing.

9
00:00:38,460 --> 00:00:48,180
And now on gigabit zero zero, I'll configure an IP version six address of 2001 face colon.

10
00:00:48,180 --> 00:00:49,200
Colon one.

11
00:00:50,650 --> 00:00:55,420
And then on gigabit to zero one shut the interface.

12
00:00:55,730 --> 00:00:59,890
IPV six address 2001 Colon 1234.

13
00:00:59,980 --> 00:01:00,520
Colon.

14
00:01:00,520 --> 00:01:01,450
Colon one.

15
00:01:01,600 --> 00:01:03,550
Slash 64.

16
00:01:04,610 --> 00:01:12,410
So show IP interface brief will show us no IP addresses because no IP version four is configured on

17
00:01:12,410 --> 00:01:22,010
this router show IPV six interface brief however shows us the IP version six Global Unicast address

18
00:01:22,010 --> 00:01:23,660
on gigabit 200.

19
00:01:25,180 --> 00:01:28,120
As well as the address on gigabit is zero one.

20
00:01:28,150 --> 00:01:31,480
So show IPV six interface gigabit.

21
00:01:31,530 --> 00:01:32,500
Zero zero.

22
00:01:33,100 --> 00:01:35,710
There is the link.

23
00:01:35,710 --> 00:01:40,960
Local address, global unicast address and subnet address.

24
00:01:42,180 --> 00:01:43,620
On gigabit to zero one.

25
00:01:43,620 --> 00:01:45,120
We've got something similar.

26
00:01:46,180 --> 00:01:50,410
Link, local address and global unicast address.

27
00:01:51,460 --> 00:01:58,060
Now one thing we need to configure on the relay agent is on the interface that's going to receive the

28
00:01:58,420 --> 00:02:00,000
DHCP request.

29
00:02:00,010 --> 00:02:11,500
We need to configure IPV six DHCP relay and point it to the DHCP server, which in this case is going

30
00:02:11,500 --> 00:02:13,720
to have an IP address of 2001.

31
00:02:14,170 --> 00:02:15,490
1234.

32
00:02:15,970 --> 00:02:16,510
Colon.

33
00:02:16,510 --> 00:02:17,740
Colon two.

34
00:02:19,340 --> 00:02:27,980
So to configure the relay agent, we configure an IP address on gigabit zero zero and we configure the

35
00:02:27,980 --> 00:02:29,720
relay destination.

36
00:02:30,110 --> 00:02:32,930
So that's the configuration of the relay agent.

37
00:02:33,110 --> 00:02:41,900
I'm going to enable IPV six DHCP debugging so that we can see DHCP messages received from the client.
