Distance Vector Multicast Routing Protocol
DVMRP is an Internet routing protocol that provides an efficient mechanism for connection-less datagram delivery to a group of hosts across an internetwork. It is a distributed protocol that dynamically generates IP Multicast delivery trees using a technique called Reverse Path Multicasting (RPM) [Deer90]. This document is an update to Version 1 of the protocol specified in RFC 1075 [Wait88].
