1
00:00:00,840 --> 00:00:08,790
In the why shock captures, we can see that the rudder is sending a rudder advertisement to f02 Colin.

2
00:00:08,790 --> 00:00:09,630
Colin one.

3
00:00:10,260 --> 00:00:17,910
So here's the advertisement link layer address is the MAC address of the rudder amp to use 1500 bytes,

4
00:00:17,910 --> 00:00:28,890
but notice now prefix information contains 2001 colon 0101 as well as 2001 colon face.

5
00:00:29,010 --> 00:00:35,580
So both of those networks are being advertised to devices on the local segment.

6
00:00:36,210 --> 00:00:39,240
Notice the PC is sending out a.

7
00:00:40,410 --> 00:00:42,210
Neighbor solicitation message.

8
00:00:42,600 --> 00:00:45,870
For this link layer address.

9
00:00:46,740 --> 00:00:50,700
With that target address 2001 face colon.

10
00:00:50,700 --> 00:00:51,390
Colon one.

11
00:00:51,390 --> 00:00:53,750
In other words, it's sending it to the writer.

12
00:00:54,450 --> 00:00:57,690
And the Rada is replying back with a neighbour.

13
00:00:57,690 --> 00:00:58,650
Advertisement.

14
00:00:59,910 --> 00:01:02,730
Telling the PC what its Mac address is.

15
00:01:03,730 --> 00:01:05,489
Here we can see the pings.

16
00:01:05,500 --> 00:01:05,860
So.

17
00:01:06,010 --> 00:01:07,990
So here's an echo request.

18
00:01:08,630 --> 00:01:11,870
From the PC to the router.

19
00:01:13,250 --> 00:01:20,420
Notice the IP version six address of the PC and IP version six address of the router, and then the

20
00:01:20,420 --> 00:01:24,920
router replies back, So 2001 Colon face colon.

21
00:01:24,920 --> 00:01:31,160
Colon one is replying back to the PC and we can see it's an echo reply.

22
00:01:31,440 --> 00:01:35,690
Here's another ping request and another ping reply.

23
00:01:36,440 --> 00:01:41,120
So a lot of what you've learnt in IP version four can be applied to IP version six.

24
00:01:41,600 --> 00:01:46,100
We have ping, we have echo requests and we have echo replies.

25
00:01:46,100 --> 00:01:47,960
But in addition we have.

26
00:01:48,590 --> 00:01:53,840
Newer protocols like neighbor solicitation and neighbor advertisement.

27
00:01:54,140 --> 00:02:00,680
One of the reasons that this is required is that broadcasts are no longer supported in IP version six.
