In a perfect world, RTRA's E0 should be responding.

What about that bridge group on RTRA? Are you actually
bridging anywhere with this setup?

Why is the RP on a spoke? Put it at the hub and
see what happens. For the hell of it I would
make E0 sparse mode and not sparse-dense mode.
I like consistancy.

Is there a LAN interface configured for RTRC?

Do you get the same behavior when pinging from each
spoke?

Have you first tried a simpler arrangement like:

RTRA is RP
RTRB/C LAN interfaces join 224.1.2.3
extended ping to 224.1.2.3 from RTRA E0
