with the same seed hash will be mapped to the same RP. If the mask
length is less than 32, then only the first portion of the hash is used,
and a single RP will be defined for multiple groups. (Range: 0-32;
Default: 10)

Priority – Priority used by the candidate bootstrap router in the
election process. The BSR candidate with the largest priority is
preferred. If the priority values are the same, the candidate with the
larger IP address is elected to be the BSR. Setting the priority to zero
means that this router is not eligible to server as the BSR. At least one
router in the PIM-SM domain must be set to a value greater than zero.
(Range: 0-255; Default: 0)

The router will act as an RP for all multicast groups in the local PIM-SM
domain if no groups are specified. A static RP can either be configured
for the whole multicast group range 224/4, or for specific group ranges.
