CHAPTER 4
Configuring DVMRP
Copyright © 2010, Juniper Networks, Inc.
E Series routers support Distance Vector Multicast Routing Protocol (DVMRP) on VRs
to forward multicast datagrams through a network. DVMRP is an interior gateway protocol
that supports operations within an autonomous system, but not between autonomous
systems. The multicast backbone of the Internet, MBone, uses DVMRP to forward
multicast datagrams. This chapter describes how to configure DVMRP on E Series routers;
it contains the following sections:
