Routing Protocol
Routing Information Protocol (RIP) V2
RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless
routing protocol, means, it includes the subnet mask with the network addresses in its routing
updates.
Due to the deficiencies of RIPv1, RIP version 2 (RIPv2) was developed in 1993 and was equipped
with the ability to support subnet information and supports Classless Inter-Domain Routing
(CIDR).
RIP's administrative distance is 120 for both RIPv1 and RIPv2.
RIPv2 sends routing updates via multicast address 224.0.0.9.
Cisco routers don't enable RIPv2 by default. To use RIPv2, you must use the ver 2 command
in RIP Router Configuration Mode.
