26.2.1 DVMRP Terminology
DVMRP probes are used to discover other DVMRP Neighbors on a network.
DVMRP reports are used to exchange DVMRP source routing information. These packets are
used to build the DVMRP multicast routing table that is used to build source trees and also
perform Reverse Path Forwarding (RPF) checks on incoming multicast packets. RPF checks
prevent duplicate packets being filtered when loops exist in the network topology.
DVMRP prunes trim the multicast delivery tree(s). DVMRP grafts attach a branch back onto
the multicast delivery tree.
26.3 Configuring DVMRP
