Use the frame-relay map clns (dlci) if using a physical interface.
Verify that you don't have a hello mismatch (ex. physical at the Hub and
at the spoke). I have seen this error message CLNS: System ID
must not change when defining additional area addresses; and it stems from
a net incorrectly and then trying to readd it. The solution is to just
remove the
ISIS routing process and then readd the net correctly. (also check your
you should follow the Gosip Nsap format or the OSI address format)

Please post your configs. Additionally you might want to check and ensure
that the kind of intf match on both ends bcos ISIS does not have any kind
of cmd similar to 'ip ospf network <type> ' to match hellos. So if you
have point-to-pt intf on one end , the other end also has to be the same.

Check and email ur config.
