Which ICMPv6 type is Router Advertisement?

Explanation:
Router Advertisement is the ICMPv6 message that routers use on the local link to announce their presence and provide configuration information to hosts. This lets devices learn about routers and perform stateless address autoconfiguration, obtaining prefixes and other parameters needed to configure themselves on IPv6 networks. It’s a router-initiated broadcast, unlike the others: a host can send a Router Solicitation to prompt routers to advertise; a Neighbor Advertisement is involved in resolving link-layer addresses and updating neighbor caches; and an Echo Reply is simply the response to a ping (Echo Request) used for basic reachability tests.
