In addition,... I think CtrMcast does not support LANs (since it is 
centralized)... you can confirm this from Polly Huang 
(huang@catarain.usc.edu)... you may want to try a detailed mulitcast 
routing agent (like detailedDM) and see what happens (to make things work 
you'd probably have to set the mac dest address of the multicast packets 
to 0 so that it gets broadcast over the LAN)... 

As Giao pointed out, we are working on this,..
