How to implement flooding for wired nodes (IP_BROADCAST usag

Hi Charles,
Thank You for the response.
Yes, I had seen it.

But what I am trying is to create my own protocol. I am trying to implement DVMRP(Distance Vector Multicast Routing).

Ofcourse there is example tcl script in ~ns2.32/tcl/ex for multicasting.
But inorder to modify the packet and embed some info into it and to test it,
I think this script is not sufficient!

So I am trying create my own own packet and first test for broadcasting(RPF) and then try multicasting based on the info in the packet…

To do this I have to start writing in C++ and define the packet first right?

But I am not able send a packet to other node by using Connector::send() and not able to receive the packet using recv()!!
I have posted the C++ source code and the errors in the previous post..

Can you please tell how to send a packet to other node using these predefined methods? Am I doing anything wrong in the code or the front end tcl script???

Thank You
