Creating a Static IGMP Group

You can configure one or more physical ports to be a permanent (static) member of an IGMP group based on the range or count. You can specify a count from 2 through 256 and up to 255 IP addresses in the range.

The following example configures two static groups starting from 226.0.0.1 using the count option.

device(config)# interface ethernet 1/1/5
device(config-if-e1000-1/1/5)# ip igmp static-group 226.0.0.1 count 2

The following example configures two static groups starting from 226.0.0.1 using the range of IP addresses option.

device(config)# interface ethernet 1/1/5
device(config-if-e1000-1/1/5)# ip igmp static-group 226.0.0.1 to 226.0.0.2

The following example configures two static groups on virtual ports starting from 226.0.0.1 using the count option.

device(config)# interface ethernet 1/1/5
device(config-if-e1000-1/1/5)# ip igmp static-group 226.0.0.1 count 2 ethernet 1/1/5

The following example configures two static groups on virtual ports starting from 226.0.0.1 using the range of IP addresses option.

device(config)# interface ve 10
device(config-vif-10)# ip igmp static-group 226.0.0.1 to 226.0.0.2 ethernet 1/1/5

The following example displays the existing static IGMP groups, use the show ip igmp static command. The vrf keyword and vrf-name variable are inserted after the igmp part of the command.

device# show ip igmp vrf eng static
