Dear ns2 experts:
I'm simulating a scenario of a sender and multiple receives. Suppose node A is
the sender, and there are two receivers: B and C.
I set 2 links: node A - node B, node A - node C.
And node A multicast packets to both node B and C.
With the following setting, from the .tr file, only node C get the packets.
What's wrong for the tcl configuration? Thanks
