[ns] Routing table contents

["Prasad V. Boddupalli" <bprasad@sie.arizona.edu>]

Hello,
    Just before adding the (dest, nextHop) pair,--- which are just node
numbers-- to the routing table, the classifer does a
    (NsObject *)TclObject::lookup(nextHop node);
what exactly is the use of this ?

thanks,
Prasad.
