DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Parameters area-id router-id authentication message-digest null hello-interval seconds dead-interval seconds authentication-key password message-digest-key keyid md5 key Specifies the identifier of the area to establish the virtual link. Specifies the Router ID of the virtual link neighbor. (Optional) Specifies authentication type. If the authentication type is not specified for the virtual-link, the simple password authentication type for the area will be used. (Optional) Specifies that MD5 authentication is used for the virtual link. (Optional) Specifies that no authentication is used. (Optional) Specifies the interval in seconds that the router sends the hello packet on the virtual link. The valid setting is 1-65535. (Optional) Specifies the interval in seconds that a neighbor is regarded as off-line if no hello packets are received within that time. The valid setting is 1-65535. (Optional) Specifies up to 8 bytes long password used for simple password authentication. (Optional) Specifies up to 16 bytes long digest key for MD5 authentication. The range of key-id is 1-255. Default Command Mode Command Default Level Usage Guideline By default no virtual-link is configured. Default authentication type is null. Default hello-interval is 10 seconds. Default dead-interval is 60 seconds. Router Configuration Mode. Level: 8. (EI Mode Only Command) In the OSPF routing domain, all areas must be connected with the backbone area. If an area disconnects from the backbone area, it requires establish a virtual link to connect the backbone area. Otherwise, the network communication will become abnormal. The virtual link requires a connection between two ABR. The area that belongs to both ABR is called the transition area. A stub Area or NSSA area cannot act as a transition area. The virtual link is a point to point link. The router will send the OSPF message to the neighbor router via unicast IP packet. The simple text authentication type and MD5 authentication type are mutually exclusive. The Dead interval must be larger than and multiple as Hello interval. Users can verify the settings by entering the show ip ospf or show ip ospf virtuallink command. Example This example shows how to configure a virtual link with neighbor 3.3.3.3 and set the authentication type to simple password with password "yourpass".
