Hi:
	I`ve tried to use lanlink but I am not really happy
with the results.  I have tried both the lanlink from the 
latest ns release with is 2.1b3, and the latest daily snapshot,
which is 2.1b4, but there is not any improvement.  Please refer to the
attachment for the output of both releases.  
	With the ns release 2.1b3, it runs until stop time, but
for the other release, it stops before stop time.  I have
been adviced by Yuri not to source vlan.tcl because for the time being,
it is not stable yet.  So, I just source the ns-lan.tcl. 
	
Thank you.

harlisya
