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 .
• Any adjacency is explicitly terminated from all OSPF interfaces.
• All previous passive-interface interface commands are removed from the
running configuration.
