Configuring MVR6 Global Settings
Use the Multicast > MVR6 (Configure Global) page to configure proxy switching and the robustness
variable.

Parameters
These parameters are displayed:
•
Proxy Switching – Configures MVR proxy switching, where the source port acts as a host, and
the receiver port acts as an MVR router with querier service enabled. (Default: Enabled)
•
When MVR proxy-switching is enabled, an MVR source port serves as the upstream or host
interface, and the MVR receiver port serves as the querier. 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.
•
Robustness Value – Configures the expected packet loss, and thereby the number of times to
generate report and group-specific queries. (Range: 1-10; Default: 1)
•
This parameter is used to set the number of times report messages are sent upstream
when changes are learned about downstream groups, and the number of times
group-specific queries are sent to downstream receiver ports.
•
This parameter only takes effect when MVR6 proxy switching is enabled.
Interface
