Hi,

The BSR constructs the RP-set from the received C-RP-set depending on the values of the RP Priority and RP Holdtime. The BSR chooses the RP from a set of C-RP for a specific multicast group based on the lower value of the RP priority (i.e., the RP having lowest value of RP priority among the C-RP-set for a specific multicast group, is chosen as the RP for that group).
If the holdtime for a RP in the C-RP-Adv message is zero, the RP is removed from the RP-set, if it is there.
Also when the CGET for a RP in the elected RP-set is expired, the RP is removed from the set.

Rgds,
Sumanta

Hi,
 
I have one confusion about RP-set construction at BSR in draft "draft-ietf-pim-sm-bsr-09".
In Section 3.3 page 19 it says
"The BSR constructs the RP-Set from the C-RP-Set.  It may apply a local
policy to limit the number of Candidate-RPs included in the RP-Set."
 
But what is the method to select RPs from the C-RP-set?
 
Please reply me if anyone knows the answer.
 
Thanks and Regards,
