mvr proxy-switching
This command enables MVR proxy switching, where the source port acts as a host, and the receiver
port acts as an MVR router with querier service enabled. Use the no form to disable this function.

Command Usage
•
When MVR proxy-switching is enabled, an MVR source port serves as the upstream or host
interface. The source port performs only the host portion of MVR by sending summarized
membership reports, and automatically disables MVR 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 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.
