No. All machines connected to a network do simple routing and most do (or should) not be running a routing daemon. > This is needed in the experiment since I need to mimic a real > environment even though I only have three machines and only one acts > as a router.

That is, they change with time and they change without operator intervention. 2) There are other devices on your network that talk RIP and your machine needs to talk to them. Both of these are true. From your description, neither of these is true. You have no additional routes to add beyond the simple ones ifconfig(8) will do for you, and there are no other routers on the network for your machine to talk to. You don't need routed. -- Crist J.
