problem working with manual routing

Hi all!!

I’m doing my Ends Career Proyect with Matlab and i need to use ns
to do some simple simulations. Unfortunately i’m new on it. I want
to work with Manual Routing, over wired networks. I’ve read the
Marc Greis’s tutorial and the NS for Beginners tutorial but they
don’t talk about it :(, and the Manual just includes a simple
paragraph and i don’t manage to run my simulation just with
it.

I’ve seen there exists two commands “add-route-to-adj-node $node”
and “add-route $node_dest $comm” to do it, and i manage to run a simple simulation using the first one, establishing default routes. But now i want to run a simple example, like this:

n0
|
|
n1

I want to send information from n0 to n2 and n3, , but i don’t find how to use the commands correctly to do it, neither in the documentation, nor at the ns mail list.

Can anyone help me please???

Thanks for any information you can give me :).

Pablo.
