– seconds: the range is from 1 to 65535 (the default is 1 second).
The transmit delay must be the same on all routers in the OSPF network.
Example of Changing and Verifying the cost Parameter and Viewing Interface Status
To view interface configurations, use the show config command in CONFIGURATION INTERFACE mode.
To view interface status in the OSPF process, use the show ip ospf interface command in EXEC mode.
The bold lines in the example show the change on the interface. The change is reflected in the OSPF configuration.

Enabling OSPFv2 Authentication
To enable or change various OSPF authentication parameters, use the following commands.
• Set a clear text authentication scheme on the interface.
CONFIG-INTERFACE mode
ip ospf authentication-key key
Configure a key that is a text string no longer than eight characters.
All neighboring routers must share password to exchange OSPF information.
• Set the authentication change wait time in seconds between 0 and 300 for the interface.
CONFIG-INTERFACE mode
ip ospf auth-change-wait-time seconds
This setting is the amount of time OSPF has available to change its interface authentication type.
When you configure the auth-change-wait-time, OSPF sends out only the old authentication scheme until the wait timer
expires. After the wait timer expires, OSPF sends only the new authentication scheme. However, the new authentication scheme
does not take effect immediately after the authentication change wait timer expires; OSPF accepts both the old as well as new
authentication schemes for a time period that is equal to two times the configured authentication change wait timer. After this
time period, OSPF accepts only the new authentication scheme.
This transmission stops when the period ends.
The default is 0 seconds.
