1
00:00:01,020 --> 00:00:08,470
In the why shock captures we can see that the rotor is sending a rudder advertisement to f f 0 2.

2
00:00:08,470 --> 00:00:10,380
Colin Colin won.

3
00:00:10,410 --> 00:00:17,190
So here's the advertisement link Lake address is the MAC address of the rather empty use fifteen hundred

4
00:00:17,190 --> 00:00:17,690
points.

5
00:00:18,090 --> 00:00:22,750
But notice now prefix information contains 2001.

6
00:00:22,890 --> 00:00:29,120
Colon 0 1 0 1 as well as 2001 colon face.

7
00:00:29,220 --> 00:00:36,320
So both those networks are being advertised to devices on the local segment.

8
00:00:36,330 --> 00:00:47,690
Notice the P.C. is sending out a neighbour solicitation message for this link later address with that

9
00:00:47,780 --> 00:00:49,100
target address.

10
00:00:49,190 --> 00:00:51,440
2001 face colon colon 1.

11
00:00:51,440 --> 00:00:57,720
In other words it's sending it to the broader and the writer is replying back with a neighbor.

12
00:00:57,740 --> 00:01:05,650
Advertisement telling the P.C. what it's a MAC address is here we can see the pings.

13
00:01:05,650 --> 00:01:05,940
So.

14
00:01:06,210 --> 00:01:17,060
So here's an echo request from the P.C. to the router notice the IP version 6 address of the P.C. and

15
00:01:17,060 --> 00:01:21,700
IP version 6 address of the rudder and then the rudder replies back.

16
00:01:21,730 --> 00:01:31,110
So 2001 colon face colon colon 1 is replying back to the P.C. and we can see it's an echo reply.

17
00:01:31,530 --> 00:01:36,210
Here's another ping request and another ping reply.

18
00:01:36,470 --> 00:01:41,660
So a lot of what you've learnt in IP version 4 can be applied to IP version 6.

19
00:01:41,780 --> 00:01:49,840
We have ping we have echo requests and we have echo replies but in addition we have newer protocols

20
00:01:50,620 --> 00:01:54,120
like enable solicitation and neighbor advertisement.

21
00:01:54,310 --> 00:02:00,490
One of the reasons that this is required is that broadcasts are no longer supported in IP version 6.
