Hi all

I have a new link I want to bring into my network, But I dont want OSPF neighbours to be formed on the link as it will most certianly be used as its a lower cost.

How would I achieve this ?

Would I just use the passive interface command? or just not include that interface IP in the network statement ?

cheers

But I agree with Inayath, if you don't have good reasons to use redistribution, the passive-interface is the better option.

Best regards

Hello Carl,

you can either use the passive-interface command (no Hellos will be sent on this interface and thus no adjacency formed) or -without a network statement for the prefix- redistribute connected networks with a route-map for the desired network(s), in this case the route type will be external.

The route type could play a role in regards of filtering/stub areas.

Hope that helps

hi

can you tell me how you would do it via a route map? can you pls give example ?

cheers

Hi Carl,

The best way is make the interface as passive interface. Or dont advertise this network into ospf domain hence there will not be ospf running for that particular interface.
