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 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.
