[ns] multicasting over unicast agent....

[Saravanan Balsubramaniyan <saro@cse.ucsc.edu>]

Hi all!
       I want to simulate a multicast routing protocol which operates over
unicast routing agent. My multicast routing protocol needs to have access
to the routing table and be capable of sending its packets to other nodes
- I want the underlying unicast routing protocol to be Distance Vector
based on Bellman Ford algo. Can anyone of you please suggest how to do
this - from where should I derive my multicast agent from? Since I need my
multicast agent to be capable of sending packets to other node and know
routing table I am confused from where I should derive my multicast agent
class from (Please note that I dont want to implement the unicast routing
myself - I want to use the already built in DV based on Bellman Ford in NS 
to be my underlying routing agent and then make my multicast agent operate
over it).

thanks,
saro.
