[ns] Accessing agents in Tcl

["Madhan Mohan" <madhan80@eth.net>]

I want to access the routing agent (like DSDV ) in my Tcl code.
How do I do that?
The variable RoutingAgent_ in Simulator class just gives the name "DSDV" and
not the agent itself.
I find that there is no function like $node_  get-agent


Thank You
