Hello GS,

I have a doubt.
Is it possible redistribute a RIP default route into OSPF?
In my lab this configuration doesn't work.

R1 fa1/9<----OSPF----->fa1/15 R2 Vlan57<-----RIP----->e0/1 R3

Configuration of R1
-------------------

router ospf 1
  router-id 10.4.4.4
  log-adjacency-changes
  area 34 range 10.0.0.0 255.0.0.0
  network 10.4.4.4 0.0.0.0 area 34
  network 163.1.0.4 0.0.0.0 area 0
  network 163.1.0.134 0.0.0.0 area 0

R1# sh ip route ospf
      163.1.0.0/16 is variably subnetted, 5 subnets, 2 masks
O E2 163.1.57.0/24 [110/20] via 163.1.0.1, 01:35:28, FastEthernet1/9

      150.1.0.0/24 is subnetted, 1 subnets
O E2 150.1.7.0 [110/20] via 163.1.0.1, 01:35:28, FastEthernet1/9
