[ns] how to invocate IGMP to use "leave-group" in multicast

[jaime venzala]

Hello, I`m working in Fedora Core5 with ns-allinone.2.29.I try to cancelled 
the comunicaton with one of the receivers of the group but not using 
"leave-group" directly. Can I invocate IGMP from NS to use "leave-group"?

Thanks a lot
