John,
Doesn't the OSPF network types of the interfaces on the routers (as you
have them) come up as 'NON_BROADCAST' and they really should be
'POINT_TO_MULTIPOINT' OSPF interface types? I can't really tell from the
reading I have done so far but, it looks like they expect only one neighbor
in that mode.
Cure:
(config-if)#ip ospf network point-to-multipoint
on each interface?
I would also think that you would want Frame Map statements on the spokes
for the other spoke?
Thanks

I thought that I would change the subject since we have beat IPX to death.
Below is a setup for a multipoint Frame network. Why does router R2 loose
all OSPF routes when the PVC to R6 comes up? Why does R3 and R6 maintain
routes from OSPF?
