RIPng is the IPv6 form of the interior gateway protocol (IGP) Routing Information Protocol (RIP), originally implemented for IPv4 routing. This protocol is a distance vector routing protocol that periodically advertises IPv6 routing information to neighbors, typically through the use of UDP based multicast updates carrying a list of one or more entries, each containing an IPv6 prefix, prefix length, route metric and a possible route tag.
RIPng is supported in the base routing context and also as a PE-CE routing protocol within a VPRN context.
