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
