A host seeking the link layer address of a neighbor multicasts a neighbor solicitation and the neighbor (if online) responds with its link layer address in a neighbor advertisement. … An IPv6 router uses this message to advertise its presence on the link. This message contains information that the interfaces on the links use to configure themselves. This information includes the router's IP address and link-layer address, whether this router can be used as default gateway router, subnet … See more A host sends this message to request IPv6 routers on the link to generate Router Advertisements immediately rather than at their next scheduled time.
