Information
Although the passive interface will neither send nor receive routing updates, the network on that
interface will still be included in OSPF updates sent via 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 interface are marked as passive.
• Any adjacency are 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.
default
Enter the keyword default to make all OSPF interfaces (current and future) passive.
