Implementing Multicast Routing on Cisco IOS XR
Software Cisco ASR 9000 Series Routers
Multicast routing is a bandwidth-conserving technology that reduces traffic by simultaneously
delivering a single stream of information to potentially thousands of corporate recipients and homes.
Applications that take advantage of multicast include video conferencing; corporate communications;
distance learning; and distribution of software, stock quotes, and news.
This document assumes that you are familiar with IPv4 and IPv6 multicast routing configuration tasks
and concepts for Cisco IOS XR software.
Multicast routing allows a host to send packets to a subset of all hosts as a group transmission rather than
to a single host, as in unicast transmission, or to all hosts, as in broadcast transmission. The subset of
hosts is known as group members and are identified by a single multicast group address that falls under
the IP Class D address range from 224.0.0.0 through 239.255.255.255.
For detailed conceptual information about multicast routing and complete descriptions of the multicast
routing commands listed in this module, you can refer to the
page MCC-97. To locate documentation for other commands that might appear in the course of executing
a configuration task, search online in the Cisco IOS XR software master command index.
