Juniper JUNOSE 11.1.X MULTICAST ROUTING, Configuration Manual

Page: 232 / 270

As described in “Overview” on page 184, hosts interact with the router through the
exchange of MLD messages. Similarly, when you configure MLD proxy, the router
interacts with the router on its upstream interface through the exchange of MLD
messages. However, when acting as the proxy, the router performs the host portion
of the MLD task on the upstream interface as follows:
■
When queried, sends multicast listener reports to the group.
■
When one of its hosts joins a multicast address group to which none of its other
hosts belong, sends unsolicited multicast listener reports to that group.
■
When the last of its hosts in a particular multicast group leaves, the group sends
either an unsolicited multicast listener done report to the all-routers address
(FF02::2) for MLDv1 or an MLDv2 multicast listener report to the all-MLDv2
routers address (FF02::16).
Configuring MLD Proxy
To configure a downstream interface, enable MLD on that interface. To configure
MLD proxy on the router, complete the following tasks:
1.
Enable IPv6 multicast.
2.
Identify the interface that you want to act as the upstream interface.
3.
Enable MLD proxy on that interface.
4.
(Optional) Specify how often the router should send unsolicited reports to routers
on the upstream interface.
ipv6 mld-proxy
■
Use to enable MLD proxy on an interface.
■
The interface for which you enable MLD proxy is the upstream interface.
NOTE: You can enable only one upstream interface.
■
You can specify either MLD proxy version 1 or 2. The default is version 2.
■
Example
host1(config-if)# ipv6 mld-proxy
■
Use the no version to disable MLD proxy on an interface.
■
See ipv6 mld-proxy.
