Filtering Groups in Proxy Report Messages

Once IGMP Proxy is configured and the router receives a query on an IGMP proxy interface, the router sends a report in response to the query before the IGMP maximum response time expires.

You can filter out groups in proxy report messages by specifying an access list name or number. This task assumes that an access list has been created to filter out one or more groups.

  1. Configure PIM globally on the router device. 
    device(config)# router pim
  2. Configure an interface (physical, virtual routing, or tunnel interface) that will serve as the IGMP proxy for an upstream device. 
    device(config)# interface ethernet 1/1/3
  3. Configure an IP address on Ethernet interface 1/1/3. 
    device(config-if-e1000-1/1/3)# ip address 10.95.5.1/24
  4. Enable PIM in passive mode on the interface. 
    device(config-if-e1000-1/1/3)# ip pim passive
  5. Enable IGMP Proxy on the interface. 
    device(config-if-e1000-1/1/3)# ip igmp proxy
  6. Filter out groups in proxy report messages using an access list. 
    device(config-if-e1000-1/1/3)# ip igmp proxy group-filter ACL1

The following example configures IGMP Proxy and filters out groups in proxy report messages using the ACL1 access list. 

device(config)# router pim
device(config)# interface ethernet 1/1/3
device(config-if-e1000-1/1/3)# ip address 10.95.5.1/24
device(config-if-e1000-1/1/3)# ip pim passive
device(config-if-e1000-1/1/3)# ip igmp proxy
device(config-if-e1000-1/1/3)# ip igmp proxy group-filter ACL1
