This command behavior has changed as follows:
passive-interface interface
The previous no passive-interface interface is removed from the
running configuration.
The ABR status for the router is updated.
Save passive-interface interface into the running configuration.
passive-interface default
All present and future OSPF interfaces are marked as passive.
Any adjacency is explicitly terminated from all OSPF interfaces.
All previous passive-interface interface commands are removed from
the running configuration.
All previous no passive-interface interface commands are removed
from the running configuration.
no passive-interface interface
Remove the interface from the passive list.
The ABR status for the router is updated.
If passive-interface default is specified, then save no passive-
interface
interface into the running configuration.
No passive-interface default
Clear everything and revert to the default behavior.
All previously marked passive interfaces are removed.
May update ABR status.
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.
