Hey, imagine I need to configure OSPF on a production device. Later some other peers will review config.
If I configure OSPF as:
router ospf 1
That means I would not establish neighbor relationships with routers yet. That means that I would avoid causing conflict in case routes I have advertise and later co-workers could access router config, see the OSPF config and if approved, then do later 'no passive-interface...' and the whole thing should work.
Is my understanding of the passive-interface default correct?
