Re: [ns] ns-2.1b8 & MNS v2

Hi Onno,
I tried your method but the "for{}" doesn't work in my ns-2.1b8 so
instead I just did something like this:

$ns node-config -MPLS ON
set LSR1  [$ns node]
$LSR1 color red

set LSR2  [$ns node]
$LSR2 color red
	:
	:
	:
set LSR9  [$ns node]
$LSR9 color red

$ns node-config -MPLS OFF

And it worked. But the system now complained about:
$ns configure-ldp-on-all-mpls-nodes

So I tried to comment out $ns configure-ldp-on-all-mpls-nodes, and then the 
system complained about:
$ns cfg-cbq-for-SBTS

So I am wondering if my ns was not "Configure" or "Make" properly.

What do you think?


Regards

Jason
