Example
This example sets the proxy query interval for MVR6.
Console(config)#mvr6 proxy-query-interval 1000
Console(config)#
mvr6 proxy-switching This command enables MVR6 proxy switching, where the source port acts as a host,
and the receiver port acts as an MVR6 router with querier service enabled. Use the
no form to disable this function.
Syntax
[no] mvr6 proxy-switching
Default Setting
Enabled
Command Mode
Global Configuration
Command Usage
◆ When MVR6 proxy-switching is enabled, an MVR6 source port serves as the
upstream or host interface, and the MVR6 receiver port serves as the querier.
The source port performs only the host portion of MVR6 by sending
summarized membership reports, and automatically disables MVR6 router
functions.
◆ Receiver ports are known as downstream or router interfaces. These interfaces
perform the standard MVR router functions by maintaining a database of all
MVR6 subscriptions on the downstream interface. Receiver ports must
therefore be configured on all downstream interfaces which require MVR6
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 MVR6 proxy switching is disabled:
■
Any membership reports received from receiver/source ports are
forwarded to all source ports.
