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. To avoid
unnecessary DF elections, HP recommends not configuring multiple RPs for BIDIR-PIM.
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. In a network with a static
RP, this configuration task is unnecessary.
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.
For C-BSRs interconnected through a GRE tunnel, configure static multicast routes to make sure the next
hop to a C-BSR is a tunnel interface. For more information about static multicast routes, see "Configuring
m
ulticast routing and forwarding."
C-BSRs should be configured on routers on the backbone network. The BSR election process is
summarized as follows:
