www.dell.com | support.dell.com Use the following command in the ROUTER OSPF mode to suppress the interface's participation on an OSPF interface. This command stops the router from sending updates on that interface. Command Syntax passive-interface {default | interface} Command Mode Usage CONFIG-ROUTEROSPF-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 Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information (e.g. passive-interface gi 2/1). • For a port channel, enter the keyword port-channel followed by a number from 1 to 255 for TeraScale and ExaScale, 1 to 32 for EtherScale (e.g. passive-interface po 100) • For a SONET interface, enter the keyword sonet followed by the slot/port information (e.g. passive-interface so 2/2). • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information (e.g. passive-interface ten 2/3). • For a VLAN, enter the keyword vlan followed by a number from 1 to 4094 (e.g. 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. The passive interface can be removed from select interfaces using the no passive-interface interface command while passive interface default is configured. To enable both receiving and sending routing updates, enter the no passive-interface interface command. When you configure a passive interface, the show ip ospf process-id interface command (Figure 413) adds the words "passive interface" to indicate that hello packets are not transmitted on that interface. 706 | Open Shortest Path First (OSPFv2)
