DGS-6604 m area virtual-link area virtual-link Use this command to configure a link between two backbone areas that are physically separated through other non-backbone area. Use the no area virtuallink command to remove a virtual link. area AREA-ID virtual-link ROUTER-ID [ authentication [ message-digest ] ] [ hello-interval SECONDS ] [ dead-interval SECONDS ] [ transmit-delay SECONDS ] [ retransmit-interval SECONDS ] [ [authentication-key PASSWORD ] | [ message-digest-key KEY-ID md5 KEY ] ] no area AREA-ID virtual-link ROUTER-ID [dead-interval|hello-interval|tansmitinterval|retransmitinterval|authentication|authentication-key|message-digest-key KEY-ID] Syntax Description AREA-ID Specifies the identifier of the transit area for the virtual link. The identifier can be specified as either an IP address or a decimal value. ROUTER-ID The Router ID of the virtual link neighbor. authentication (Optional) Specifies authentication type. If no authentication type is specified for the virtual-link, the authentication type for the area will be used. message-digest (Optional) Specifies that message-digest authentication be used. hello-interval SECONDS Specifies the interval in seconds, between the hello packets that the router sends on an interface. The valid setting is 1-65535. dead-interval SECONDS Specifies the interval in seconds, during which no packets are received and after which a neighbor is regarded as off-line. The valid setting is 1-65535. transmit-delay SECONDS The interval the router waits before it transmits a packet. The valid setting is 165535. retransmit-interval SECONDS The interval the router waits before it retransmits a packet. The valid setting is 165535. authentication-key PASSWORD (Optional) Password to be used by neighboring routers. The passsword is a continuous string of keyborad characters up to 8 bytes long. This password is a key to allow the authentication procedure to generate or verify the authentication field contained in the OSPF header. The authentication key is inserted directly into the OSPF header when originating routing protocol packets. Each network can be assigned a separate password on a per-interface basis. All neighboring routers on the same network must use the same password to be able to route OSPF traffic. message-digest-key KEY-ID md5 KEY (Optional) Key identifier and password to be used for Message Digest 5 (MD5) authentication by neighboring routers and this router. The KEY-ID argument is a number in the range from 1 to 255. The KEY consists of an alphanumeric string of up to 16 characters in length. All neighboring routers on the same network must have the identical key identifier and key, to be allowed to route OSPF traffic. There is no default value. CLI Reference Guide 47
