To suppress the interface's participation on an OSPF interface, use the following command in ROUTER OSPF mode. This command stops the router from sending updates on that interface. Command Syntax passive-interface {default | interface} Command Mode Usage CONFIG-ROUTER-OSPF-id Specify whether all or some of the interfaces will be passive. Default enabled passive interfaces on ALL interfaces in the OSPF process. Entering the physical interface type, slot, and number enable passive interface on only the identified interface. • For a port channel, enter the keyword port-channel followed by a number from 1 to 128 • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information (for example, passive-interface ten 2/3). • For a VLAN, enter the keyword vlan followed by a number from 1 to 4094 (for example, passive-interface vlan 2222). • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE followed by the slot/port information. The default keyword sets all interfaces on this OSPF process as passive. To remove the passive interface from select interfaces, use the no passive-interface interface command while passive interface default is configured. To enable both receiving and sending routing updates, use the no passive-interface interface command. When you configure a passive interface, the show ip ospf process-id interface command adds the words "passive interface" to indicate that hello packets are not transmitted on that interface (Figure 20-13).
