These commands display information about IGMP Groups and Mrouters
learned by the switch.
A static multicast router (Mrouter) can be configured for a particular port on a
particular VLAN. A static Mrouter does not have to be learned through IGMP
Snooping. Any data port can accept a static Mrouter.
When you configure a static Mrouter on a VLAN, it replaces any dynamic Mrouters
learned through IGMP Snooping.
Use the following procedure to configure a static multicast router (Mrouter):
1. For each Mrouter, configure a port or trunk group (1 through 24 or po1 through
), VLAN (1 through 4094), and version (1 through 3).
po24
ex2500(config)# ip igmp mrouter 5 1 2
The IGMP version is set for each VLAN, and cannot be configured separately for
each Mrouter.
2. Verify the configuration.
ex2500(config)# show ip igmp mrouter
