RE: preferring one route over the other

Thanks, I might do this using metric on the default-info orig point, and
possibly route-map it only to the routers that I want to alter the metric
for

As you stated R3 is OSPF neighbored with R1/R2 you can

You can do any of these to effect which default route R3 chooses (towards R2
over R1)

1. Set the metric on R1's to higher than the default (20)

2. Set the metric on R2's to LOWER than the default (20)

3. Set metric type to E1 on R2's redistribution (E1 is preferred over E2)

I'm sure there are other ways...

I have 3 routers..

R1 and R2 both have internet connections and learn 0/0 via bgp from upstream
isp

R3 connects and ospf neighbors with R1 and R2 over a single vlan. R1 and R2
send 0/0 to R3 via default info-orig

R3 learns dual def route (2) 0/0's...equal cost, and thus adds (2) 0/0's to
routing table

I want to now change this

I want R3 to prefer one of those 0/0's over the over 0/0

I want R3 to prefer R2's def route.

How would you suggest I do this?
