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.
