Are there any options to modify this behavior? If R1 and R3 are announcing the same group, is there a way to modify the default behavior and make R1 the preferred RP without adding higher IP address on R1?

The Mapping Agents serve as the Rendezvous Point election agency by listening to the Cisco Announce group to receive Candidate-RP Announcements, selecting the highest IP address Candidate-RP for a group range and then multicast the election results to the 224.0.1.40 Cisco Discovery group. All Cisco routers in the network automatically join the 224.0.1.40 group so that they can learn the IP address of the elected Rendezvous Point for each group range.

If there are two RPs announcing the same group, how does the mapping agent decide which RP to announce for the group? What is the criteria for the election process? Thanks.

I’m still a bit unsure about tracking with multiple objects, and using the and/or boolean, so I was wondering if the above configuration would be considered correct or not?
