UDP transport works!

I setup two routing instances, well basically two subdirectories, with the program and IOS in the parent.

r1

..\dynamips.exe -P 7200 -X --sparse-mem -T 7200 -t npe-200 ..\C7200-IS.BIN -p 0:C7200-IO-FE -s 0:0:udp:10000:127.0.0.1:10001

r2

..\dynamips.exe -P 7200 -X --sparse-mem -T 7201 -t npe-200 ..\C7200-IS.BIN -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10000

And I've been running an extended ping, with the sweep size.
