Hi,
   
  Could you be a little more specific in the question please?
   
  Are you looking for a multicast source and receiver to be able to find each other even if the RP for the group being used is down? If so I believe dense mode fallback is on by default and should work. Or is it the case of wanting one RP to be primary for half the groups and secondary RP for the other half and be able to become the RP for all groups if the other RP fails?

  Hi , let see , If I configure 2 routers for sparse-dense mode.
r1 is rp for half of the administrately scope ,
r2 is the rp for the second half.
r3 send the discovery.
everybody uses auto-rp.

But if one RP fails routers must try to learn the multicast groups dynamically .
How could I resolve this?
