Dear shima Manual routing is an option for wired routing, you can do it by firstly typing $ns rtproto Manual and then adding your disired route by add-rout-to-adj-node like below: $ns duplex-link $n1 $n2 10Mb 100ms DropTail $n1 add-route-to-adj-node -default $n2 $n2 add-route-to-adj-node -default $n1 I should tell you if you search for it in list there are many error, not solved yet.
