Configuring IGMP Proxy

To configure a downstream interface, enable IGMP on that interface. To configure IGMP proxy on the router, complete the following tasks:

1. Enable IP multicast.

   host1(config)#ip multicast-routing

2. Identify the interface that you want to act as the upstream interface.
3. Enable IGMP proxy on that interface.

   host1(config-if)#ip igmp-proxy

4. (Optional) Specify how often the router sends unsolicited reports to routers on the upstream interface.

   host1(config-if)#ip igmp-proxy unsolicited-report-interval 600

5. (Optional) Specify how long the router calculates an IGMPv1 querier router to exists on the subnetwork after the router receives an IGMPv1 query on this interface.

   host1(config-if)#ip igmp-proxy V1-router-present-time 600
