Correction - I am indeed seeing an issue. It shows up again with IGRP as
well. All routes are in the routing table with the appropriate next hop as
the hub interface address. But extending ping tests in conjunction with the
debug frame packet reveal that on the spokes there can be issues. it is
interesting how it occurs. Depending upon how I do things, pings will work
from router to router to router.
Hub
/ \
interface-spoke_1 spoke_2-interface
ping from spoke interface to spoke interface seem to be fine. Regular old
ping seems not to work.
more later, after I do some more testing

Subject: More Frame Relay stuff - EIGRP
After spending some time looking at OSPF / Frame relay interactions, I took
a cue from someone else on the list and looked at EIGRP. The basic setup is
that of bootcamp lab 1 - hub and spoke, but using inverse arp only. Recall
that in the bootcamp lab one must use local policy configs to solve the
routing problem that occurs.
Interesting. Here is what I observed:
Using inverse arp only, ( no manual frame map statement ), and once I
cleared all the ip local policy statements left over from my ospf configs on
all routers, I had a converged routing table. All eigrp routes showed the
next hop as the address of the hub router on the frame cloud. This is
definitely different than what occurs with OSPF, which shows the frame cloud
addresses of the originating router, as you recall from bootcamp.
Once I eliminated the ospf artifacts on all routers, and once I had disabled
eigrp split horizon on the hub interface, there were no issues at all with
routing.
I will be repeating this exercise with the other routing protocols, just to
see what happens.
