Configuring DVMRP

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:
