Prioritize BSR Candidates

LAN prune delay is disabled in the system by default. This example configures VLAN 5 as a BSR candidate with a preference value of 20. VLAN 5 is used as the BSR unless another router is identified as a BSR candidate with a higher bsr-candidate value.

1. Enable PIM globally.

   SEFOS# configure terminal
   SEFOS(config)# set ip pim enable
   

2. Enter Interface Configuration mode for the interface.

   SEFOS(config)# interface vlan 5
   

3. Associate the VLAN interface with the PIM component.

   SEFOS(config-if)# ip pim componentId 1
   

4. Specify how often (in seconds) the switch sends PIM messages to the interface.

   SEFOS(config-if)# ip pim query-interval 60
   

5. Configure the candidate preference for the PIM interface VLAN 5 as 20.

   SEFOS(config-if)# ip pim bsr-candidate 20
   SEFOS(config-if)# end
   

6. Ensure that the correct BSR preference is set.

   SEFOS# show ip pim bsr
