Configure IGMP Relay

Use the following procedure to configure IGMP Relay.

1. Configure an IP interface and assign VLANs.

>> /cfg/l3/if 2	(Select IP interface 2)
>> IP Interface 2# addr 10.10.1.1	(Configure IP address for IF 2)
>> IP Interface 2# mask 255.255.255.0	(Configure mask for IF 2)
>> IP Interface 2# vlan 2	(Assign VLAN 2 to IF 2)
>> /cfg/l3/if 3	(Select IP interface 3)
>> IP Interface 3# addr 10.10.1.2	(Configure IP address for IF 3)
>> IP Interface 3# mask 255.255.255.0	(Configure mask for IF 3)
>> IP Interface 3# vlan 3	(Assign VLAN 3 to IF 3)

2. Turn IGMP on.

>> /cfg/l3/igmp/on

(Turn on IGMP)

3.Enable IGMP Relay and add VLANs to the downstream network.

>> /cfg/l3/igmp/relay/ena			(Enable IGMP Relay)
>> IGMP Relay# add 2			(Add VLAN 2 to IGMP Relay)
Vlan	2	added.
>> IGMP Relay# add 3			(Add VLAN 3 to IGMP Relay)
Vlan	3	added.

4.Configure the upstream Mrouters.

>>IGMP Relay# mrtr 1/addr 100.0.1.2/ena

Current IP address: 0.0.0.0

New pending IP address: 100.0.1.2

Current status: disabled

New status: enabled

>>Multicast router 1# ..

>>IGMP Relay# mrtr 2/addr 100.0.2.4/ena

Current IP address: 0.0.0.0

New pending IP address: 100.0.2.4

Current status: disabled

New status: enabled
