PurposeCommand or Action
Example:
Device(config-if)# ip igmp
proxy-service
•
When the mroute proxy service is enabled, the device periodically
checks the static mroute table for (*, G) forwarding entries that match
interfaces configured with the ip igmp mroute-proxy command (see
Step 7) based on the IGMP query interval. Where there is a match,
one IGMP report is created and received on this interface.
The ip igmp proxy-service command is intended to be used with
the ip igmp helper-address (UDL) command.
Note
•
In this example, the ip igmp proxy-service command is configured
on loopback interface 0 to enable the forwarding of IGMP reports out
the interface for all groups on interfaces registered through the ip
igmp mroute-proxy command (see Step 7).
Ends the current configuration session and returns to privileged EXEC
mode.

Example:
Device(config-if)# end
