through the exchange of IGMP messages. However, when acting as the proxy, the
router performs the host portion of the IGMP task on the upstream interface, as
follows:
■
When queried, sends group membership reports to the group.
■
When one of its hosts joins a multicast address group to which none of its other
hosts belong, sends unsolicited group membership reports to that group.
■
When the last of its hosts in a particular multicast group leaves the group, sends
an unsolicited leave group membership report to the all-routers group (244.0.0.2).
Configuring IGMP Proxy
To configure a downstream interface, enable IGMP on that interface. To configure
IGMP proxy on the router, complete the following tasks:
1.
Enable IP multicast.
host1(config)#
ip multicast-routing
2.
Identify the interface that you want to act as the upstream interface.
3.
Enable IGMP proxy on that interface.
host1(config-if)#
ip igmp-proxy
4.
(Optional) Specify how often the router sends unsolicited reports to routers on
the upstream interface.
host1(config-if)#
ip igmp-proxy unsolicited-report-interval 600
5.
(Optional) Specify how long the router calculates an IGMPv1 querier router to
exists on the subnetwork after the router receives an IGMPv1 query on this
interface.
host1(config-if)#
ip igmp-proxy V1-router-present-time 600
ip igmp-proxy
■
Use to enable IGMP proxy on an interface.
■
The interface for which you enable IGMP proxy is the upstream interface.
NOTE:
You can enable only one upstream interface.
■
You can specify either IGMP proxy version 2 or 3. The default is version 2.
■
Example
host1(config)#
ip multicast-routing
host1(config-if)#
ip igmp-proxy
■
Use the
no
version to disable IGMP proxy on an interface.
■
See ip igmp-proxy.
ip igmp-proxy unsolicited-report-interval
