DHCPv6 uses UDP/547 on server and UDP/546 on client with link scope
unicast or mutlicast addresses.

Router Advertisment utilizes ICMP6, Router solicitation type to
link scope multicast ff02::02 by client and Router advertisment type to
link scope multicast ff01::01 by server. Source addresses are link scope
unicast addresses in both directions.
