Add static routing support:
# Turn on manual routing. $ns rtproto Manual # Set manual routes $nodeA add-route $nodeC $nodeB $nodeC add-route $nodeA $nodeB results in this information being returned from the tmcd routing command: ROUTERTYPE=manual ROUTE DEST=192.168.2.3 DESTTYPE=host DESTMASK=255.255.255.0 \ NEXTHOP=192.168.3.2 COST=0 The reason for DESTTYPE and DESTMASK is so that we can also support routing to links and lans, since doing it on a per host basis if not only hugely tedious, but plain impossible if the destination node has multiple links; the add-route syntax takes a node, but we need the IP of the relevant link in order to run the route add commands on the nodes. So, I've "extended" the syntax of add-route so that you can give it a Link or a Lan as the dest: $nodeA add-route $link0 $nodeB $nodeA add-route [$ns link $nodeB $nodeC] $nodeB In this case, the DESTTYPE=net, and the netmask is no longer ignored; it is used in the route add command. Currently, the mask is hardwired in the DB to 255.255.255.0, but by providing it in the tmcd command, we change it later if needed. I did not implement add-route-to-adj-node since that is not really useful in our context, and we definitely do not want the user to change the default routes on his nodes. But, its easy to add if we need to. The client side stuff is not done yet.
