passive-interface

Suppress both receiving and sending routing updates on an interface.

Syntax

passive-interface {default | interface}

To enable both the receiving and sending routing, use the no passive-interface interface 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 (current and future) passive.
interface	Enter the following keywords and slot/port or number information: For Port Channel groups, enter the keywords `port-channel` then a number. The range is from 1 to 128. For a 10-Gigabit Ethernet interface, enter the keyword `TenGigabitEthernet` then the slot/port information. For a VLAN, enter the keyword `vlan` then a number from 1 to 4094.

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.
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.

No passive-interface default

Clear everything and revert to the default behavior.
All previously marked passive interfaces are removed.
May update ABR status.
