Core Knowledge Question of the Day: 12 March 2009

Which process uses ICMP messages and solicited-node multicast addresses to determine the link-layer address of a neighbor on the same network (local link), verify the reachability of a neighbor, and track neighboring routers?

Highlight for answer: The IPv6 neighbor discovery process.



  1. My shot in the dark would be the “OSPF” process

  3. Yep, the ipv6 nd!!

    Its got nothing to do with ospf, guess the keywords here are “ICMP” and “solicited-node multicast addresses”.

    Keeo them coming. 😀
