Users Guide

The default keyword sets all interfaces as passive. You can then configure individual
interfaces, where adjacencies are desired, using the no passive-interface
interface command. The no form of this command is inserted into the configuration
for individual interfaces when the no passive-interface interface command is
issued while
passive-interface default is configured.
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.
