Hi all,
Iam trying to implement multicasting over MPLS network with PIM-SM(source based tree)..I modified the classifier-addr-mpls.cc and classifier-addr-mpls.h files and recompiled using "make depend" , "make" commands to suppor MPLS multicasting in NS2.35.. But when I run the tcl file Iam getting the following errors: Error: while executing "proc attach-expoo-traffic { node sink size burst idle rate }" (file "multimpls.tcl" line 16) karthick@linux:~/ns-allinone-2.35$ ns proj2.tcl using backward compatible Agent/CBR; use Application/Traffic/CBR instead ns: _o35 routing-nochange 2 0.05410933552271: can't schedule command in past (_o5 cmd line 1) invoked from within "_o5 cmd at 0.05410933552271 {_o34 ldp-trigger-by-routing-table}" invoked from within "catch "$self cmd $args" ret" invoked from within "if [catch "$self cmd $args" ret] { set cls [$self info class] global errorInfo set savedInfo $errorInfo error "error when calling class $cls: $args" $..."
