Abstract
RIP Version 2 extends RIPv1 with subnet mask support (VLSM), next-hop fields, route tags for BGP interaction, and optional MD5 authentication. Routers broadcast the full routing table every 30 seconds using UDP port 520 and limit network diameter to 15 hops. RFC 2453 obsoletes RFC 1723.
Why This RFC Matters
RIPv2 brought classless routing and authentication to the simple distance-vector protocol that dominated early IP networks. Although largely superseded by OSPF and IS-IS in large networks, RIPv2 remains common in small branch offices and embedded devices because of its minimal configuration overhead. Its well-understood simplicity makes it a baseline teaching tool for understanding distance-vector routing concepts, split horizon, and poison reverse.
