IPv6 router solicitation is:

Internet Protocol version 6 (IPv6) is the next-generation Internet Layer protocol for packetswitched internetworks and the Internet. IPv6 router solicitation is:

A.
A request made by a node for the IP address of the local router

B.
A request made by a node to join a specified multicast group

C.
A request made by a node for a DHCP provided IP address

D.
A request made by a node for the IP address of the DHCP server

Explanation:
In cases when the host (computer or server) needs to prompt an immediate router advertisement,
it sends what is called as a Router Solicitation. Examples of this include commands for re-booting
or re-starting a running computer. The system is alerted through router solicitation.
Router solicitation messages belong to the ICMPv6 set of messages, specific to the IPv6 protocol.
They are identified by a Next Header value “x’3A and decimal 58.
An IPv6 router solicitation is closely associated to the Neighbor Discovery (ND) function of the
IPv6. Under this, the hosts or routers obtain or discover the link-layer addresses for elements that
reside on attached links (neighbor) and to cleansed or purge spaces with cached values that are
no longer functioning.
