hi Jeff,
  Can you give me an example for number 3. Don't know
how to do it.
Thanks,
Angelo

I'm thinking about this config.

int loopback 0
 ip address 10.1.1.1 255.255.255.0

router ospf 10
  redistribute connected metric-20 subnets route-map
loop1

route-map loop1 permit 10
   match interface loopback 0

or

access-list 1 permit 10.1.1.0 0.0.0.255

route-map loop1 permit 10
   match ip address 1
