Command Usage
â—† 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.
â—† Receiver ports are known as downstream or router interfaces. These interfaces
perform the standard MVR6 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.
â—† When the source port receives report and leave messages, it only forwards
them to other source ports.
â—† When receiver ports receive any query messages, they are dropped.
â—† When changes occurring in the downstream MVR6 groups are learned by the
receiver ports through report and leave messages, an MVR6 state change
report is created and sent to the upstream source port, which in turn forwards
this information upstream.
â—† When MVR6 proxy switching is disabled:
â–
Any membership reports received from receiver/source ports are
forwarded to all source ports.
â–
When a source port receives a query message, it will be forwarded to all
downstream receiver ports.
â–
When a receiver port receives a query message, it will be dropped.
