Wonder whether combination of auto-rp and static rp will work. Beside
configuration auto-rp, adding two static rp-address entries to each
router. If auto-rp works, it overrides the static rp-addresses. If
auto-rp fails, static rp-addresses will be effective. Kind of like a
floating routing for RP..

that is it :
" 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 ".
Can I use ip pim rp-candidate for both groups but with differente
priorities ? So I will have two RPs , one for half of the groups? If one
fail - by priorities the other can assume the entire function?
Can I user just AUTO-RP for this?
ps: the questions asks to use PIM V2.
Thanks Chris.

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?
