authentication (Protocols OSPF)

Configures a simple authentication password string, defined by key.

Configure an MD5 password.

• key-identifier—MD5 key identifier. Range is from 0 through 255. Default is 0.

• key key-values—One or more MD5 key strings. The MD5 key values can be from 1 through 16 characters long. You can specify more than one key value within the list. Characters can include ASCII strings. If you include spaces, enclose all characters in quotation marks (“ ”).

• start-time time—MD5 start date and time, in the format YYYY-MM-DD.hh:mm.

Configure authentication type MD5 with multi active keys

• key-identifier—multi active MD5 key identifier. Range is from 0 through 255. Default is 0.

• key key-valuesOne or more MD5 key strings. The MD5 key values can be from 1 through 16 characters long. You can specify more than one key value within the list. Characters can include ASCII strings. If you include spaces, enclose all characters in quotation marks (“ ”).

• delete-if-not-inuse—Delete this key if not in use. This option added under multi-active-md5 for an OSPF interface marks the key as old. If a new key is available on an OSPFv2 interface and once all the neighbors on the OSPFv2 interface use the new key, then OSPFv2 stops sending OSPFv2 packets with key that is marked as delete-if-not-inuse.

For each keychain, you must specify a name. For example, ospf_auth. You can have multiple keychains on a routing device. For example, you can have a keychain for OSPF, a keychain for BGP, and a keychain for LDP.
