You can configure an OSPF interface as passive to prevent OSPF routing
traffic from exiting or entering that interface. No OSPF adjacency can be
formed if one of the interfaces involved is set to passive mode. The
specified interface will appear as a stub in the OSPF domain. Also, if you
configure an OSPF interface as passive where an adjacency already exists,
the adjacency will drop almost immediately.
