RIP ( Routing Information Protocol ) is the next step to go farer into dynamic IPv6 networking. RIPng builds on the foundations of RIPv2, but adds IPv6 support. RIPng stands for ' RIP next generation '
Like RIPv2, RIPng is a distance-vector routing protocol. It is based on hop count, and thus make nodes choose the shortest path hop-count-wise. The limit is 15 hops, so the network size musn't exceed this limit.
some important notes :
RIPng doesn't support updates authentication ( while RIPv2 does )
RIPng doesn't allow arbitrary tags on routes, neither next-hop encoding ( while RIPv2 does )
RIPng is multicast using the multicast group ff02::9 ( all RIP Routers link-local )
