IGMP Proxy Routing
This section describes commands used to configure IGMP Proxy Routing on the
switch.
To enable IGMP proxy service, follow these steps:
1. Use the ip multicast-routing command to enable IP multicasting globally on
the router.
2. Use the ip igmp proxy command to enable IGMP proxy on the upstream
interface that is attached to an upstream multicast router.
3. Use the ip igmp command to enable IGMP on the downstream interfaces from
which to forward IGMP membership reports.
4. Optional – Use the ip igmp proxy unsolicited-report-interval command to
indicate how often the system will send unsolicited reports to the upstream
router.
ip igmp proxy This command enables IGMP proxy service for multicast routing, forwarding IGMP
membership information monitored on downstream interfaces onto the upstream
interface in a summarized report. Use the no form to disable proxy service.
