Now ICMP Version 6 also includes neighbor discovery protocol messages and the two of interest here are
a solicitation or arrests and rudder advertisement or a.
So write a solicitation message is sent to all IP version 6 riders.
In other words f f 0 2.
Colon colon to Rodders on the local segment will be subscribed to that multicast address and they will
reply back with rudder advertisements so run advertisements or sent by riders and include information
such as the link local IP version 6 address of the rudder and the local segment riders advertise themselves
using multicast address f f 0 2 colon colon 1 which is all devices on the local segment a host as an
example will boot up and send a message to f f 0 2 colon colon 2 to ask all riders to identify themselves
the riders will then reply back with their link local address riders also send unsolicited rider advertisement
messages on a periodic basis they will advertise their details on the IP version 6 link and they send
that again to f f 0 2 colon colon 1 now by leveraging neighbor Discovery Protocol a broader solicitation
and or advertisement messages hosts can discover which subnet they belong to surround us by using Slack
can advertise the local prefix and linked to hosts on the local segment.
So let's have a look at that practically.
