Information About IPv6 Neighbor Discovery
The IPv6 neighbor discovery process uses ICMPv6 messages and solicited-node multicast addresses to
determine the link-layer address of a neighbor on the same network (local link), verify the readability of
a neighbor, and keep track of neighboring routers.
Nodes (hosts) use neighbor discovery to determine the link-layer addresses for neighbors known to
reside on attached links and to quickly purge cashed values that become invalid. Hosts also use neighbor
discovery to find neighboring routers that are willing to forward packets on their behalf. In addition,
nodes use the protocol to actively keep track of which neighbors are reachable and which are not, and to
detect changed link-layer addresses. When a router or the path to a router fails, a host actively searches
for functioning alternates.
This section includes the following topics:

Neighbor Solicitation Messages, page 1-2
•
Neighbor Reachable Time, page 1-2
•
Duplicate Address Detection, page 1-2
