8320 passive interface default

Hi,

On my 8320 I can see under the router OSPF commands an option to enter passive interface default.

I couldn’t see an option to turn off this command one interface at a time (no passive interface 1/1/1)

How do you allow for certain ports ... or is the switch smart enough to see which ports you have configured for OSPF under this command?

Thanks

You can configure individual interfaces as passive OSPF ports from the interface context:

 

switch(config)# interface 1/1/1
switch(config-if)# ip ospf passive

Simply no ip ospf passive on the interface.

Here is an example of SVI with ospf:

 

interface vlan251
vrf attach prod
ip address 10.1.251.2/29
ip ospf 10 area 0.0.0.0
no ip ospf passive
ip ospf cost 100

Re: 8320 passive interface default

If I may, FYI, a best practice applied I saw on many large ITs, is to passive all interface and activate only the one that should be active.

Re: 8320 passive interface default

Would that look like

Router OSPF 1
Passive interface default

Interface 1/1/1
IP OSPF 1 area 0 - this bit here is what I’m unsure about?

Does this command override the passive interface default?
