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.
