Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs - Dynamically Finding the RP Using BSR

3 important questions on Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs - Dynamically Finding the RP Using BSR

What is the difference between auto-rp and bsr?

-BSR router does not pick best RP for each multicast group, but send all group-to-RP mapping information
-PIM routers pick best RP for each multicast group by running the same has algorithm (on the information in the bootstrap message).

If two BSR are configured, which BSR will win? What happens if a preferred BSR fails?

-Highest-priority BSR wins
-If a tie highest BSR IP address wins

Redundant BSR can take over

What is the command to configure a router as a candidate RP?

(config)#ip pim rp-candidate loopback X
