Configuring DVMRP

Overview

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:

NOTE: PIM has gained general acceptance among a large number of multicast-enabled
networks. We recommend that you use PIM rather than DVMRP for applications that
are not otherwise required to run DVMRP.
