Hello guys

I tried to run MN2 with ns-2.1b8 for like 3 weeks but got nothing done, so I 
decided to do it in ns-2.1b6
now.

I installed ns successfully and followed the install guide in MNS. After 
everything is done, I tried to run
a example file of mpls but still failed!!!

The system said:

    (_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)


This result is the same as the one I got when I use ns-2.1b8.
I am really confused, someone please help!!!

Jason Liu

P.S. I install ns-2.1b6 but I still have ns-2.1b8 in my unix computer, is 
this reason???
