Re: [ns] Wired-cum-wireless-sim.tcl -> error when slightly modified

[Padmaparna Haldar <haldar@ISI.EDU>]

I'm not sure if there is any easy way of debugging this. You'd have to 
step thru a debugger to find out which node's classifier is complaining 
about not having the target which the route in the pkt header is
indicating. In other words, the routing table doesnot know the 
next-hop for the destination of the packet. 
Especially check the point where classifiers get populated. 
The tcl command $ns gen-map should help you map the tcl objects.
See ns-debugging page for hints on C++/OTcl debugging.

Hope this helps,
