Re: PIM accept RP diff from RP Mapping?

Hi Kelvin,

Ip pim rp-address tells the router where to send joins/prunes and other
messages that need to get to the RP. Ip pim accept-rp is used to filter
joins/prune messages. The (*,G) join contains the RP address, so any routers
along the path may filter them based on RP or Group address.
