PIM BSR RP-Candidate Versus BSR RP-Candidate Election Process
Configuration for N7K-1:
interface loopback0
ip address 192.168.1.1/32
ip pim sparse-mode
ip pim bsr bsr-candidate loopback0
ip pim bsr rp-candidate loopback0 group-list 224.1.1.0/24
ip pim bsr forward listen
Configuration for N7K-2:
interface loopback0
ip address 192.168.2.1/32
ip pim sparse-mode
ip pim bsr bsr-candidate loopback0
ip pim bsr rp-candidate loopback0 group-list 224.0.0.0/4
ip pim bsr forward listen
Verification for N7K-1:
show ip pim group 224.1.1.0
PIM Group-Range Configuration for VRF "default"

224.0.0.0/4
Verification for N7K-2:
show ip pim group 224.1.1.0
PIM Group-Range Configuration for VRF "default"
Group-range
224.1.1.0/24
show ip pim group 224.3.0.0
PIM Group-Range Configuration for VRF "default"
Group-range
224.0.0.0/4
•
• When multiple BSR RP-candidates advertise the same group list (for example, 224.0.0.0/4), the system
elects the BSR RP-candidate with the highest priority (lowest numerical value) as the RP for any multicast
address specified in its group list (see configuration example 2).
• Configuration example 2—Identical group list with different RP priorities: In this example, the

system elects the device labeled N7K-1 as the RP for all multicast addresses specified in the
224.0.0.0/4 group list because it has the lowest RP-candidate priority. The device labeled N7K-2
has a default priority of 192.
