1
00:00:00,720 --> 00:00:07,960
Now ICMP Version 6 also includes neighbor discovery protocol messages and the two of interest here are

2
00:00:08,400 --> 00:00:13,480
a solicitation or arrests and rudder advertisement or a.

3
00:00:13,860 --> 00:00:19,030
So write a solicitation message is sent to all IP version 6 riders.

4
00:00:19,120 --> 00:00:21,490
In other words f f 0 2.

5
00:00:21,490 --> 00:00:29,230
Colon colon to Rodders on the local segment will be subscribed to that multicast address and they will

6
00:00:29,230 --> 00:00:36,160
reply back with rudder advertisements so run advertisements or sent by riders and include information

7
00:00:36,160 --> 00:00:43,600
such as the link local IP version 6 address of the rudder and the local segment riders advertise themselves

8
00:00:43,810 --> 00:00:51,670
using multicast address f f 0 2 colon colon 1 which is all devices on the local segment a host as an

9
00:00:51,670 --> 00:01:00,130
example will boot up and send a message to f f 0 2 colon colon 2 to ask all riders to identify themselves

10
00:01:00,790 --> 00:01:08,950
the riders will then reply back with their link local address riders also send unsolicited rider advertisement

11
00:01:08,950 --> 00:01:17,380
messages on a periodic basis they will advertise their details on the IP version 6 link and they send

12
00:01:17,380 --> 00:01:25,880
that again to f f 0 2 colon colon 1 now by leveraging neighbor Discovery Protocol a broader solicitation

13
00:01:25,910 --> 00:01:33,290
and or advertisement messages hosts can discover which subnet they belong to surround us by using Slack

14
00:01:33,710 --> 00:01:40,810
can advertise the local prefix and linked to hosts on the local segment.

15
00:01:41,210 --> 00:01:42,920
So let's have a look at that practically.
