Configuring Igmp Proxy - Juniper JUNOSE 11.1.X MULTICAST ROUTING Configuration Manual

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:

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.
2.
3.
4.
5.
ip igmp-proxy
NOTE: You can enable only one upstream interface.
ip igmp-proxy unsolicited-report-interval
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).
Enable IP multicast.
host1(config)#ip multicast-routing
Identify the interface that you want to act as the upstream interface.
Enable IGMP proxy on that interface.
host1(config-if)#ip igmp-proxy
(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
(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
Use to enable IGMP proxy on an interface.
The interface for which you enable IGMP proxy is the 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.
