Multicast VLAN Registration for IPv6
– 675 –
4.
For multicast streams that will run for a long term and be associated
with a stable set of hosts, you can statically bind the multicast
group to the participating interfaces (see "Assigning Static MVR6
Multicast Groups to Interfaces" on page 684 ).

ARAMETERS
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
