To enable both the receiving and sending routing, use the no passive-interfaceinterface command.To return all OSPF interfaces (current and future) to active, use the no passive-interface default command.Parameters default Enter the keyword default to make all OSPF interfaces (currentand future) passive.interface Enter the following keywords and slot/port or number information:• For a Gigabit Ethernet interface, enter the keywordGigabitEthernet followed by the slot/port information.• For Port Channel groups, enter the keywords port-channel followed by a number. For the C-Series and S-Series, the range is 1 to 128. For the E-Series, the range is 1 to32 for EtherScale and 1 to 255 for TeraScale.• For a SONET interface, enter the keyword sonet followed bythe slot/port information.• For a 10-Gigabit Ethernet interface, enter the keywordTenGigabitEthernet followed by the slot/portinformation.• For a VLAN, enter the keyword vlan followed by a numberfrom 1 to 4094.• For a 40-Gigabit Ethernet interface, enter the keywordfortyGigE followed by the slot/port information.Command Modes ROUTER OSPFCommand History Version 8.3.11.1 Introduced on the Z9000.Version 8.3.7.0 Introduced on the S4810.Version 7.8.1.0 Added support for Multi-Process OSPF.Version 7.6.1.0 Introduced on the S-Series.Version 7.5.1.0 Introduced on the C-Series.Version 7.4.1.0 Modified to include the keyword default.pre-Version6.1.1.1Introduced on the E-Series.UsageInformationAlthough the passive interface will neither send nor receive routing updates, the network onthat interface will still be included in OSPF updates sent using other interfaces.The default keyword sets all interfaces as passive. You can then configure individualinterfaces, where adjacencies are desired, using the no passive-interfaceinterface command. The no form of this command is inserted into the configuration forindividual interfaces when the no passive-interface interface command isissued while passive-interface default is configured.This command behavior has changed as follows:passive-interface interface1066
