CtrMcast

[Hugh Smith <smithh@cse.msu.edu>]

I am trying to use CtrMcast but am unable to get it to work.  If I just
do:

set ns [new Simulator -multicast ignored_flag 
set mproto CtrMcast
set mrthandle [$ns mrtproto $mproto {} ]

set scn [new Scenario]
.
.
.
$ns run


My simulation runs but I do not get many packets at the receivers.  I
cannot really tell why.  It's like they are not being routed at all.  I
do not get any errors.  When I use DM, it works fine.

Any ideas?  Hugh
