Distance Vector Multicast Routing Protocol (DVMRP) is a dense mode
multicast protocol and is most appropriate for use in networks where
bandwidth is relatively plentiful and there is at least one multicast group
member in each subnet. DVMRP assumes that all hosts are part of a
multicast group until it is informed of multicast group changes. When the
dense-mode multicast router is informed of a group membership change, the
multicast delivery tree is pruned. DVMRP uses a distributed routing
algorithm to build per-source-group multicast trees. It is also called Broadcast
and Prune Multicasting protocol. It dynamically generates per-source-group
multicast trees using Reverse Path Multicasting. Trees are calculated and
updated dynamically to track membership of individual groups.
ip dvmrp
Use the ip dvmrp command to set the administrative mode of DVMRP in the
router to active. Enabling DVMRP concurrently enables IGMP/MLD. Using
the no form of the command sets the administrative mode to inactive and
disables IGMP/MLD.
