PASSIVE-INTERFACE

Syntax

passive-interface INTERFACENAME A.B.C.D

Parameter

INTERFACENAME

Specifies the name of the interface.

A.B.C.D

Specifies the IP address of the interface.

Description

Use the PASSIVE-INTERFACE command to suppress routing updates on
the specified interface.

This command is used to configure OSPF on simplex Ethernet interfaces.
Since the simplex interfaces represent only one network segment
between two devices, configure the transmitting interface as a passive
interface. This ensures that OSPF does not send hello packets for the
transmitting interface. Both of the devices can see each other via the hello
packet generated for the receiving interface.

Command Mode

Router mode

Example

The following commands suppress hello packets on interface 7:

switch#configure terminal

switch(config)#router ospf 100

switch(config-router)# passive-interface xe7
