R3 is going to use the Frame-relay map command under the physical
interface.
Next the configuration that was provided for the spokes (by Stephen)
will work fine, since you disabled inverse arp on the spokes the DLCI's
need to be specified.
Using that configuration doesn't configure L3 - L2 mapping on the
physical interface for the spokes.
Thanks

Stephen,
I don't see how this would help. All DLCI's are assigned to the physical
interface by default, so assigning the DLCI with that command here does
nothing. Also this is a multipoint interface, so without some layer 3 to
layer 2 mapping, no packets are going anywhere.
Arun, I believe the IE lab solution guide gives a working config, can't
you look at that? From memory I think the OSPF section gives a clue as
to how spoke to spoke connectivity is achieved. On the hub you can still
use map statements.
