Configuring IP Multicast in a Layer 2 Switched Ethernet Network

Perform this task to configure IP multicast in a Layer 2 Switched Ethernet network using RGMP.
OL-29890-01
Purpose
Enters global configuration mode.
Selects an interface that is connected to hosts on which IGMPv3 can
be enabled.
Enables CGMP on an interface of a device connected to a Cisco
Catalyst 5000 family switch.
• The proxy keyword enables the CGMP proxy function. When
enabled, any device that is not CGMP-capable will be advertised
by the proxy router. The proxy router advertises the existence
of other non-CGMP-capable devices by sending a CGMP Join
message with the MAC address of the non-CGMP-capable device
and group address of 0000.0000.0000.
Ends the current configuration session and returns to EXEC mode.
(Optional) Clears all group entries from the caches of Catalyst switches.
