Usage Information
Although the passive interface does not send or receive routing updates, the network on that interface is still
included in OSPF updates sent using other interfaces.
The default keyword sets all interfaces as passive. You can then congure individual interfaces, where
adjacencies are desired, using the no passive-interface interface command. The no form of this
command is inserted into the conguration for individual interfaces when the
no passive-interface
interface command is issued while passive-interface default is congured.
This command behavior has changed as follows:
passive-interface interface
• The previous no passive-interface interface is removed from the running conguration.
• The ABR status for the router is updated.
• Save passive-interface interface into the running conguration.
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 conguration.
• All previous no passive-interface interface commands are removed from the running
conguration.
no passive-interface interface
• Remove the interface from the passive list.
• The ABR status for the router is updated.
