Mahesh,

I don't know how you came to the conclusion that routing is using
hop-count as metric (maybe the confusing code variable names ;) ?) but
no, routing is using link costs as metrics

In the patch I've just sent to the list there is a piece of code
(commented with //---- Cut here --  ) that will actually dump the
routing table (next hop to that destination and minimum cost to that
destination). IIRC there is a top-level procedure in ns that dumps the
routing table content (check the ns manual).


Cheers,

Florian
