11IP Multicast Routing

This chapter describes the components of IP multicast routing, and how to configure IP multicast routing on the Summit.

For more information on IP multicasting, refer to RFC 1112, RFC 1075,

RFC 2236, and other more recent Internet draft documents.

OVERVIEW

IP multicast routing is a function that allows a single IP host to send a packet to a group of IP hosts. This group of hosts can include devices that reside on the local network, within a private network, or outside of the local network.

IP multicast routing consists of the following functions:

•A router that can forward IP multicast packets.

•A router-to-router multicast protocol (for example, Distance Vector Multicast Routing Protocol or DVMRP).

•A method for the IP host to communication its multicast group membership to a router (for example, Internet Group Management Protocol or IGMP).
