OSPFv3 Passive Interface

Like OSPFv2, OSPFv3 has the ability to set an interface as passive.

There are two modes in that passive-interface can be used, one will blacklist certain interfaces that are specified. The other will blacklist all interfaces by default and only interfaces that are explicitly specified will be whitelisted to participate in the OSPF process.

To blacklist only certain interfaces, for example FastEthernet0/0:

router ospfv3 1

passive-interface FastEthernet0/0

To blacklist all interfaces, and only allow certain ones to participate in OSPF, such as FastEthernet0/1:

router ospfv3 1

passive-interface default

no passive-interface FastEthernet0/1
