ip pim sparse on loopback?

Is there any reason why you need to enable ip pim sparse-mode on a loopback address? even if you point the RP to the loopback?

Re: ip pim sparse on loopback?

Hello Jeffrey,

when using auto RP, the mapping agent needs ip pim sparse-mode on its loopback interface to process advertisements from candidate RPs.

This is the only strict requirement I'm aware of.

Hope to help

Giuseppe
