IPv6 Neighbor Discovery
One area in which IPv4 networking is made more complicated is in locating
servers, routers, configuration data, and generally in making it possible
for nodes to determine what other nodes are nearby (on the same link)
and what nodes are remote (off-link). Neighbor Discovery (ND) for IPv6
is defined in RFC 2461, “Neighbor Discovery for IPv6,” and it provides
an important tool that not only simplifies network administration and
management but also enables a much greater degree of scaling in IPv6
network size.
This chapter compares how ND is specified and implemented in IPv4 and
IPv6, followed by a discussion of some of the roles ...
