[ns] how to access rtPeer and dvr table class objects from c++ source code in creating new RPF check

[siva rupesh ss]

hi,
    I am trying to write a modified DVMRP protocol for multicasting

In order to do that i want to write a new RPF( Reverse Path Forwarding)
check
by adding additional field to the packet .

>From ns manual ,in chapter 29 there is a class rtPeer and RouteLogic to
access  all the neighbor addresses of a node  and DV routing
tables  in tcl code

But there is no information regarding how to  access those objects using
C++  source code

Can anyone help me regarding this...

Thank You
Rupesh
