Configuring Router-Port Group Management Protocol

RGMP Configuration Task List

Enabling RGMP

To enable RGMP, use the following commands on all routers in your network beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# interface type number	Specifies the router interface on which you want to configure
		RGMP and enters interface configuration mode.
Step 2
	Router(config-if)# ip rgmp	Enables RGMP on a specified interface.

See the “RGMP Configuration Example” section later in this chapter for an example of how to configure RGMP.

Verifying RGMP Configuration

To verify that RGMP is enabled on the correct interfaces, use the show ip igmp interface EXEC command:

Router> show ip igmp interface

Ethernet1/0 is up, line protocol is up Internet address is 10.0.0.0/24 IGMP is enabled on interface Current IGMP version is 2

RGMP is enabled

IGMP query interval is 60 seconds IGMP querier timeout is 120 seconds

IGMP max query response time is 10 seconds Last member query response interval is 1000 ms Inbound IGMP access group is not set

IGMP activity: 1 joins, 0 leaves Multicast routing is enabled on interface Multicast TTL threshold is 0

Multicast designated router (DR) is 10.0.0.0 (this system) IGMP querying router is 10.0.0.0 (this system)

Multicast groups joined (number of users): 224.0.1.40(1)

Note If RGMP is not enabled on an interface, no RGMP information is displayed in the show ip igmp interface command output for that interface.
