RE: ospf passive-interface

If you're trying to make the interface behave like a RIP passive interface, you can use the database-filter all out, but you'll need to remove the passive interface. The adjacency will still need to be formed for the routes to be received from your neighbor.

All,

When you define passive-interface under ospf you don't send hellos and pretty
much don't send any routes for the interface for which it is passive. This can
be changed with the "ip ospf database-filter all out" command which should
allow for to receive routes but not send routes. Right?

I was testing this but did not got the right results.

!
interface Ethernet0/0
 ip address 10.10.10.1 255.255.255.0
 ip ospf database-filter all out
!
router ospf 1
 log-adjacency-changes
 passive-interface Ethernet0/0
 network 1.1.1.1 0.0.0.0 area 0
 network 10.10.10.1 0.0.0.0 area 0
!

I did not see any ospf routes in the routing table,

R1#sh ip route ospf
