Detailed explanation-1: -The RA contains the network part of the Layer 3 IPv6 address (IPv6 Prefix). The host uses the IPv6 prefix provided by the RA; generates the universally unique host part of the address (interface identifier), and combines the two to derive the complete address.
Detailed explanation-2: -The RA message contains important information for nodes as well as which method they should use to obtain their IPv6 address. The RA contains several flags that are set that the nodes watch for and use. ICMPv6 RAs are intended to help facilitate bootstrapping the connectivity of an IPv6 node on a network.
Detailed explanation-3: -Router Solicitation (RS): Sent to the “all-IPv6-routers” local-scope multicast address of FF02::2, so that the message asks all routers, on the local link only, to identify themselves. Router Advertisement (RA): This message, sent by the router, lists many facts, including the link-local IPv6 address of the router.
