Managing IGMP Proxies
You can configure an interface to proxy for a single multicast group or a
range of multicast groups. You can also display and delete IGMP proxies.
Configuring Proxies
Before configuring an interface to proxy for multicast groups, note that:
■ You must assign an IP address to that interface.
■ You cannot configure an interface to proxy for a multicast group within
the multicast range 224.0.0.0 to 224.0.0.255.
■ If the interface is configured to proxy for multiple multicast groups, the
most specific match acts as the proxy for that interface. However, if the
interface proxies for the same multicast address ranges, the metric value
determines which address range is used.
Use this procedure to configure interfaces to proxy for multicast groups:
Task Command
1. Enter root mode. root
2. Specify the multicast address or
address range, mask, metric, and
interface that will act as the proxy.
ip igmp proxy <group-address>
<group-mask> metric <number>
<c/s/i>
