MVR for IPv6
– 1249 –
◆ Receiver ports are known as downstream or router interfaces. These
interfaces perform the standard MVR router functions by maintaining a
database of all MVR subscriptions on the downstream interface.
Receiver ports must therefore be configured on all downstream
interfaces which require MVR proxy service.
◆ When the source port receives report and leave messages, it only
forwards them to other source ports.
◆ When receiver ports receive any query messages, they are dropped.
◆ When changes occurring in the downstream MVR groups are learned by
the receiver ports through report and leave messages, an MVR state
change report is created and sent to the upstream source port, which in
turn forwards this information upstream.
◆ When MVR proxy switching is disabled:
■
Any membership reports received from receiver/source ports are
forwarded to all source ports.
■
When a source port receives a query message, it will be forwarded
to all downstream receiver ports.
■
When a receiver port receives a query message, it will be dropped.
E XAMPLE
The following example enable MVR proxy switching.
Console(config)#mvr proxy-switching

This command configures the expected packet loss, and thereby the
number of times to generate report and group-specific queries. Use the no
form to restore the default setting.
