Dear all,
I am using the MPLS simulator for ns-2.1b8a-win
(win NT).
I'm trying to run the essai.tcl but I 'm getting
the following errors. I used exactly the same code from tutorial, it's not
running. The errors that I'm getting are :
(_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 LSR2 [$ns MPLSnode]" (file "essai.tcl" line 18.
Someone who know this problem,
Please help me.
Thanx.
