[ns] Using multicast

[Jos� Santiago <jcbs@mafalda.inesc.pt>]

Hi everybody,

When I added multicast instructions to cbr-TSW3CM.tcl example, I got the
error message written below. I can't understand it because I don't have any
node with a handle like _o15 in my topology, and how procedure "_o15" can
appear here. I think that it is more than a simple coincidence. Worst than
this, I can't imagine how ns gets an index equated to " -1".  Can anybody
help?


 ns: _o15 new-group 0 -2147483648 -1 wrong-iif: can't read "inLink_(-1)": no
such element in array
while executing
"subst $[subst $var"
    (procedure "_o10" line 5)
