Command Modes ROUTER OSPF Command History Version 7.8.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 7.4.1.0 pre-Version 6.1.1.1 Introduced support for Multi-Process OSPF. Introduced on S-Series Introduced on C-Series Modified to include the default keyword. Introduced on E-Series Usage Although the passive interface will neither send nor receive routing updates, the network on that Information 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.
