Configuring IP Multicast Routing
This chapter describes how to configure IP multicast routing on the Catalyst 3750-X or 3560-X switch.
IP multicasting is a more efficient way to use network resources, especially for bandwidth-intensive
services such as audio and video. IP multicast routing enables a host (source) to send packets to a group
of hosts (receivers) anywhere within the IP network by using a special form of IP address called the IP
multicast group address. The sending host inserts the multicast group address into the IP destination
address field of the packet, and IP multicast routers and multilayer switches forward incoming IP
multicast packets out all interfaces that lead to members of the multicast group. Any host, regardless of
whether it is a member of a group, can send to a group. However, only the members of a group receive
the message.
To use this feature, the switch or stack master must be running the IP services feature set. To use the PIM
stub routing feature, the switch or stack master can be running the IP base image.
Note Multicast routing is not supported on switches running the LAN base feature set.
Unless otherwise noted, the term switch refers to a Catalyst 3750-X or 3560-X standalone switch and to
a Catalyst 3750-X switch stack.
