Re: [ns] cooperation between wired and wireless rp's

[Praveen Yalagandula <ypraveen@wins.hrl.com>]

Check out the Figure 16.3 in manual "Schematic of a baseStation
Node". The hierarchical classifiers in the node are responsible for the
routing and not the DSDV agent, if the address in a packet is of wired
nodes. These classifiers are populated with the routing information abt
the wired world and the wireless world is handled by the DSDV agent.. The
classifiers just forward the packets to DSDV agent which is the
default target.

If you would like to see the code about the classifiers, check the
ns-rtmodule.tcl and classifier-hier.cc.
