Setting 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, do not configure 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.
