[ns]Quick ques - prompt response will be appreciated

Hi,

I'd appreciate to have some of my questions cleared ASAP.

#1. If a simple network with two paths to the destination, can I force the 
packets to follow an explicit route. If yes, how can I implement this?

#2. I have a topology where in i am using DV routing. I try the experiment 
with different traffic sources(CBR, Exponential UDP, TCP). The first two 
works fine but TCP doesn't. Yes my immediate reaction was to change the 
window size (default is 20 which i changed to 500). Even after doing so I 
see nothing in the trace except for the routing information exchanged 
between the routers. The script neither gives any errors when executed. Any 
suggestions?

My topology is,

  10 - 11 - 12 - 13
/                 \
0 - 1 - 2 - 3 - 4 - 5
         \	   /
	  6 - 7 - 8

#3. I understand that in the ns-2.1b7, mpls is incorporated. But when I 
execute an example, fail-reroute.tcl it gives an error
"_o3: unable to dispatch method MPLSnode". I went through the bugs need to 
be fixed and it seems okay. Am I missing here anything?

I'd appreciate your prompt response.

Thanks,
Arun
