For DLSW Lite, apart from the "frame-relay map llc2" command that is needed if
"multipoint" sub-interface is used, is there any other trick to DLSW Lite:-
I have the following lab setup:-
WebCentrall11 -- RTA --- Frame-Relay Switch --- RTB -- HARDCAT-LAPTOP
When I initiate traffic by clicking on Network Neighborhood, I can see the MAC
addresses showing up from the "show bridge" command & "show dlsw reachability" & I
can also see the DLSW peers' states as Connect. Yet the circuit keeps on getting
to the CKT_START state, then the circuit will disappear, and I can't see the
other computer via Network Neighborhood.

But the DLSW circuit just stays at "CKT_START"...

And here's the config:-

It woluld be greatly appreciated if anyone can shed some light on this.
