Use <strong>the</strong> following command in <strong>the</strong> ROUTER OSPF mode to suppress <strong>the</strong> interface’s participation on an<br />

OSPF interface. This command stops <strong>the</strong> router from sending updates on that interface.<br />

Command Syntax Command Mode Usage<br />

passive-interface {default |<br />

interface}<br />

CONFIG-ROUTER-<br />

OSPF<br />

Specify whe<strong>the</strong>r all or some of <strong>the</strong> interfaces will be<br />

passive.<br />

Default enabled passive interfaces on ALL interfaces<br />

in <strong>the</strong> OSPF process.<br />

Entering <strong>the</strong> physical interface type, slot, and number<br />

enable passive interface on only <strong>the</strong> identified<br />

interface.<br />

• For a Gigabit E<strong>the</strong>rnet interface, enter <strong>the</strong> keyword<br />

GigabitE<strong>the</strong>rnet followed by <strong>the</strong> slot/port<br />

in<strong>for</strong>mation (e.g. passive-interface gi 2/1).<br />

• For a port channel, enter <strong>the</strong> keyword<br />

port-channel followed by a number from 1 to 255<br />

<strong>for</strong> TeraScale, 1 to 32 <strong>for</strong> E<strong>the</strong>rScale (e.g.<br />

passive-interface po 100)<br />

• For a SONET interface, enter <strong>the</strong> keyword sonet<br />

followed by <strong>the</strong> slot/port in<strong>for</strong>mation (e.g.<br />

passive-interface so 2/2).<br />

• For a 10-Gigabit E<strong>the</strong>rnet interface, enter <strong>the</strong><br />

keyword TenGigabitE<strong>the</strong>rnet followed by <strong>the</strong><br />

slot/port in<strong>for</strong>mation ( e.g. passive-interface ten 2/<br />

3).<br />

• For a VLAN, enter <strong>the</strong> keyword vlan followed by a<br />

number from 1 to 4094 (e.g. passive-interface<br />

vlan 2222).<br />

The default keyword sets all interfaces on this OSPF process as passive. The<br />

passive interface can be removed from select interfaces using <strong>the</strong> no<br />

passive-interface interface command while passive interface default is<br />

configured.<br />

To enable both receiving and sending routing updates, enter <strong>the</strong> no passive-interface interface<br />

command.<br />
