We have a 4 router network that looks like a baseball diamond, with a router at home (R0), first (R1), second (R2) and third (R3) bases.
They are connected as a single area0. There are no cross connections across the diamond.
The internet is connected to the outward facing interface on R0 at home base.
There are presently static default routes at R2 second base pointing to R1 at first base, and a default at R1 pointing to R0 at Home. Home of course has a default route pointing to the internet.
In the same manner R3 at third base also has a default route pointing to R0 at home.
Let's say the link between R2 and R1 goes down. Now i want the traffic to automagically go from R2 to R3 to R0, but the static default route at R2 still points to R1 which now goes nowhere.
How do I set up ospf to allow my default routes to 'float' and rearrange themselves to the best configuration so
nothing goes down during this outage?
