If you're using physical interfaces and there are two spokes in the
network then two frame relay map statements on each router should fix
this problem.  The issue is that RTRA can't ping the interface on RTRC
because it has no map for it.  If you turn on debug ip packet you'll see
'encapsulation failed'.  Warning:  Don't use that command in a
production network.  

Anyway, on each spoke, add a map statement for the IP address of the
other spoke.  I'm assuming you have one configured for the hub.  If not,
add one because you're relying on inverse ARP to map the address of the
hub.  Once you add an explicit frame relay map statement, inverse ARP is
disabled for that protocol.  Things will still work until you reboot
your router.  :-)

split horizon is NEVER an issue with OSPF. Nor with BGP

If you are using the physical interfaces in all cases, and you are
trying to
ping the directly connected interface of the other side, your pings
will
fail. This is true of all routing protocols. At least according to the
extensive experimentation and resulting observation when I did these
tests
last September. I've never brought it up as a topic of discussion
because I
could not come up with a conceptual framework that explained the
phenomenon.
I do have a note indicating that static maps must exist for all
directly
connected addresses to overcome this problem.

betcha if you use an extended ping, and use something other than the
directly connected interface as your source address it works fine.
