Enabling Auto-RP listening
This feature enables the switch to receive Auto-RP announcement and discovery messages
destined for 224.0.1.39 and 224.0.1.40 respectively and to learn the RP for each multicast group.
To enable Auto-RP listening:

Configuring the maximum number of BIDIR-PIM RPs
In a BIDIR-PIM domain, one DF election per RP is implemented on all PIM-enabled interfaces. As a
best practice to avoid unnecessary DF elections, do not configure multiple RPs.
This configuration sets a limit on the number of BIDIR-PIM RPs. If the number of RPs exceeds the
limit, excess RPs do not take effect and can be used only for DF election rather than multicast data
forwarding. The system does not delete the excess RPs. They must be deleted manually.

Configuring a BSR

You must configure a BSR if C-RPs are configured to dynamically select the RP. You do not need to
configure a BSR when you have configured only a static RP but no C-RPs.
A BIDIR-PIM domain can have only one BSR, but must have at least one C-BSR. Any router can be
configured as a C-BSR. Elected from C-BSRs, the BSR is responsible for collecting and advertising
RP information in the BIDIR-PIM domain.
Configuring a C-BSR
IMPORTANT:
Because the BSR and other devices exchange a large amount of information in the BIDIR-PIM
domain, reserve a large bandwidth between the C-BSR and other devices.
