Dear Polly Huang

Using Node allocaddr eliminated error of my first question - no target for slot
error.  However, it did not solve problem with getting multicast tree.
I am using "ns 2.1b4".  I notice that CtrMcastComp.tcl has routine for
computing multicast tree.  Is there any way to find out which nodes are in the
tree?  

Thanks
