Fwd: Re: [ns] ns-2.1b8 & MNS v2
Hi there!
I followed Christian Glomb's steps to run mns in ns-2.1b8 but in the end
still no luck.
The system kept saying the same thing when I run test-*.tcl files:
(_o3 cmd line 1)
invoked from within
"_o3 cmd MPLSnode"
invoked from within
"catch "$self cmd $args" ret"
(procedure "_o3" line 2)
(SplitObject unknown line 2)
invoked from within
"$ns MPLSnode"
invoked from within
"set LSR1 [$ns MPLSnode]"
(file "test-constraint-routing.tcl" line 94)
Can anyone give me some advice?
