Expected RP/Mapping Agent Behavior for Multicast

Hello:

Quick question for you all. I have tried to implement this on a lab, but
having trouble finding out exact expected behavior. When I want to
specifically assign a certain group to a certain RP, do I have to make that
specification with which of these commands?

1. ip pim rp-announce-filter rp-list 1 group-list 2 on the Mapping Agent
2. ip pim send-rp-announce l0 scope 16 group-list 1 on the Candidate RP

Or do I need to do it on both? Also, will only the RPs that are relevant to
groups the router is "participating" in (meaning the ip igmp join/static
group command was issued on it) show up in the "show ip mroute" output, or
will ALL RPs show up there? Thanks in advance for all your help.
