Hi ,
the command show ip rpf x.x.x.x also check if the source is reachable from
interface running PIM , so x.x.x.x being in the routing table is not enough .

From the vrf table, there is a route for the destination 172.9.11.1. Just
don't know why it fail the RPF lookup.

prot=1, len=114(100), RPF lookup failed for source or RP
R8#show ip rpf vrf ABC 172.9.11.1
RPF information for ? (172.9.11.1) failed, no route exists
R8#
R8#show ip route vrf ABC
