That sounds like this: " When started (or when a network interface is later turned on), routed uses an AF_ROUTE address family facility to find those directly connected interfaces configured into the system and marked "up". It adds necessary routes for the interfaces to the kernel routing table. Soon after being first started, and provided there is at least one interface on which RIP has not been disabled, routed deletes all pre-existing non- static routes in kernel table. Static routes in the kernel table are preserved and included in RIP responses if they have a valid RIP metric (see route(8))." > And when should routed even be used? Do you have a need to perform dynamic routing? Most people don't...a static route to a default gateway works fine. -- -Chuck
