31.3.0.0.4 Manual Routing

Manual routing is not a route computation protocol (like the others), but simply a way for users to configure the routing table by hand, much as you would with the ``route'' command on a workstation.

To use manual routing, enable it with rtproto, then set each nodes routing tables with the add-route-to-adj-node command. For example:

$ns rtproto Manual
set n1 [$ns node]
set n2 [$ns node]
$ns duplex-link $n1 $n2 10Mb 100ms DropTail
$n1 add-route-to-adj-node -default $n2
$n2 add-route-to-adj-node -default $n1
