Use <strong>the</strong> show config command in CONFIGURATION INTERFACE mode (Figure 387)to view interface<br />

configurations. Use <strong>the</strong> show ip ospf interface command in EXEC mode to view interface status in <strong>the</strong><br />

OSPF process.<br />

Enable OSPF au<strong>the</strong>ntication<br />

Use <strong>the</strong> following commands in CONFIGURATION INTERFACE mode to enable or change various<br />

OSPF au<strong>the</strong>ntication parameters:<br />

Command Syntax Command Mode Usage<br />

ip ospf au<strong>the</strong>ntication-key key CONFIG-INTERFACE Set clear text au<strong>the</strong>ntication scheme on <strong>the</strong><br />

interface. Configure a key that is a text<br />

string no longer than eight characters.<br />

All neighboring routers must share <strong>the</strong> same<br />

password to exchange OSPF in<strong>for</strong>mation.<br />

ip ospf auth-change-wait-time<br />

seconds<br />

The change is made on <strong>the</strong><br />

interface and it is reflected in<br />

<strong>the</strong> OSPF<br />

CONFIG-INTERFACE Set <strong>the</strong> au<strong>the</strong>ntication change wait time in<br />

seconds between 0 and 300 <strong>for</strong> <strong>the</strong><br />

interface. This is <strong>the</strong> amount of time OSPF<br />

has available to change its interface<br />

au<strong>the</strong>ntication type. During <strong>the</strong><br />

auth-change-wait-time, OSPF sends out<br />

packets with both <strong>the</strong> new and old<br />

au<strong>the</strong>ntication schemes. This transmission<br />

stops when <strong>the</strong> period ends. The default is 0<br />

seconds.<br />
