Hi, I'm a new user of ns3, and i'm having some troubles with nsclick. I
started to create small networks to get familiar with nsclick, and after
this, i will try to create a data center network. Basically, i tried to
expand the example nsclick-routing.cc. I'm using 4 hosts and 2 routers, in
this way:
(10.0.k.x)
Host2 Host3
(2.2) (3.2)
(2.X)\ /(3.X)
(2.1) (3.1)
Router2
(4.2)
(4.X)|
(4.1)
Router1
(0.2) (1.2)
(0.x)/ \(1.X)
(0.1) (1.1)
Host0 Host1
The host 0 sends udps to host 3, and the host 3 should make an echo of the
udps. However, the router 1 isn't passing the udps.
If, anyone could help me, i would be very grateful.
