suppose to have one network with OSPF as IGP and PIM-SM for multicast.
Suppose that a router (R0) is in a Stub area and know the RP and the Mcast Source with the same default route for RPF check.
After that Source start to send traffic, do you thik that RPT-> SPT transition should happens... actually we do not have a shorter tree... because R0 known RP and Mcast Source with the same cost...?!
I'd like to understand if R0 send prune message to RP or not.
