3. Set the interfaces that will join the MVR as source ports or receiver ports
(see “Configuring MVR6 Interface Status” on page 608).
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 610).
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.
