21 DVMRP
DVMRP (Distance Vector Multicast Routing Protocol) is an Internet Routing Protocol that
provides efficient mechanism for connectionless message multicast to a group of hosts across an
internetwork.
Distance Vector Multicast Routing Protocol, an interior gateway protocol (IGP) suitable for use
within an autonomous system but not between different autonomous systems.
DVMRP is based on RIP. DVMRP combines many of the features of RIP with the Truncated
Reverse Path Broadcasting (TRPB) algorithm. To allow experiments to traverse networks that do
not support multicasting a mechanism called tunneling was developed. DVMRP tunnels multicast
transmission within unicast packets that are reassembled into multicast data when they arrive at
their destination.
The key differences between DVMRP and RIP are RIP routes and forwards datagrams to a
particular destination. The purpose of DVMRP is to keep track of the return paths to the source of
the multicast datagrams.
The list of CLI commands for the configuration of DVMRP is as follows:
set ip dvmrp
ip dvmrp prune-life-time
set ip dvmrp - interface
debug ip dvmrp
show ip dvmrp
