- 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.

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. Open Shortest Path First (OSPFv2 and OSPFv3) 647
