not including a interface in ospf

Hi all

I have configured a link between 2 of my sites but I dont want any routes learnt over this link, so I have used the passive interface command.

However when I do a >show ip ospf interface, the interface shows in here.

I would of though the passive interface command would have stopped this ?

cheers

Carl

not including a interface in ospf

Hi Carl,

This is normal. The show ip ospf interface will show both active and passive interfaces in OSPF because the network that is directly connected to a passive interface will still be advertised in OSPF. Rest assured, a router will never form adjacencies over passive interfaces. Also, the show ip ospf interface should say something similar to:

Vlan128 is up, line protocol is up

[ ... cut for brevity ... ]

  Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

    oob-resync timeout 40

    No Hellos (Passive interface)

Check it out.

Best regards,

Peter
