To configure a router to be an RP candidate, I originally thought that you would need to enter the "ip pim rp-address <interface ip>" command.
But what if we're running the RP candidate on a network with sparse-dense mode? If we enter "ip pim rp-address <interface ip>", will IOS interpret that to mean that we have defined an RP for all multicast group addresses (224.0.0.0/4)?
Can we run a router as an RP candidate in sparse-dense mode without entering the "ip pim rp-address <interface ip>" command so that multicast traffic can be dense mode flooded?
