Usage Information

By default, no interfaces are passive. Routing updates are sent to all interfaces on which the routing protocol is enabled.

If you disable the sending of routing updates on an interface, the particular address prefix continues to be advertised to other interfaces, and updates from other routers on that interface continue to be received and processed.

OSPFv3 for IPv6 routing information is not sent or received through the specified router interface. The specified interface address appears as a stub network in the OSPFv3 for IPv6 domain.

On configuring suppression using the passive-interface command, the state of the OSPF neighbor does not change to INIT; instead, the state of the OSPF neighbor changes to DOWN after the dead-timer expires.
