Looking at it more closely,
I noticed that your R1 int s0.1 is a multipoint and the router on the other
side is R2 int s0.1 and it is point-to-point. When setting up this type of
network the serial interfaces on all sides of a p-to-m should be set to
multipoint. When both sides are set this way the routing characteristics
will be consistent among all participating routers. This is probably not
your problem, however.
On router R2, I don't see the frame map clns statement.
R1(hub)/R2(spoke)/?(spoke) are point-to-multipoint. Participating routers
based on the subnet of the int. It appears that there is only one spoke at
this time.
On router R3, there is a frame map clns statement and I don't think you need
one there. R3/R1 are point-to-point FR right?
