[Q:Rush]Upstream node.



Hi, all

I try to make a new multicast protocol.
So I've tested following topology.

Node0 ------- Node1 ---------- Node2 -------Node3
packet-------->1
                          ----------------->2
                         3 <----------------
                          ------------------->4

I want to send a packet in order 1->2->3->4.
But I cann't test 3 because I don't know how to send upstream node.

I must know upstream node.

Can you know how to? please, let' me know....
