The basic routing lookup is done through class Routelogic's lookup{}
call (~ns/tcl/lib/ns-route.tcl) which looks up routing tables (in
~ns/route.cc); lookup takes 2 node ids as args and returns the nexthop
for node 1 to reach node 2.

You may want to take a look at chp 14 (unicast routing) of ns
documentation for other routing mechanisms in ns.
