ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual 12. Use Authentication Type to select an authentication type other than none. You can select the authentication type from the pull-down menu. The choices are: • None: This is the initial interface state. If you select this option from the pull-down menu, no authentication protocols will be run. • Simple - If you select 'Simple' you will be prompted to enter an authentication key. This key will be included, in the clear, in the OSPF header of all packets sent on the network. All routers on the network must be configured with the same key. • Encrypt - If you select 'Encrypt' you will be prompted to enter both an authentication key and an authentication ID. Encryption uses the MD5 Message-Digest algorithm. All routers on the network must be configured with the same key and ID. 13. Use Authentication Key to enter the OSPF Authentication Key for the specified interface. If you do not choose to use authentication you will not be prompted to enter a key. If you choose 'simple' authentication you cannot use a key of more than eight octets. If you choose 'encrypt' the key may be up to 16 octets long. The key value will only be displayed if you are logged on with Read/Write privileges, otherwise it will be displayed as asterisks. 14. Use Authentication Key ID to enter the ID to be used for authentication. You will only be prompted to enter an ID when you select 'Encrypt' as the authentication type. The ID is a number between 0 ad 255, inclusive. 15. Use Metric Cost to enter the link cost. OSPF uses this value in computing shortest paths. The range is from 1 to 65,535. Table 32.
