Use this command to define a virtual link. To remove a virtual link, use the no form with no optional keywords. To restore the default value for an attribute, use the no form with the required keyword.

no area area-id

•area-id- Identifies the transit area for the virtual link. (The area ID must be in the form of an IP address.)

•router-id- Router ID of the virtual link neighbor. This must be an Area Border Router (ABR) that is adjacent to both the backbone and the transit area at the other end of the virtual link.

•authentication - Specifies the authentication mode. If no optional parameters follow this keyword, then plain text authentication is used along with the password specified by the authentication-key. If message-digestauthentication is specified, then the message-digest-keyand md5 parameters must also be specified. If the null option is specified, then no authentication is performed on any OSPF routing protocol messages.

•message-digest- Specifies message-digest (MD5) authentication.

•null - Indicates that no authentication is used.

•hello-intervalseconds - Specifies the transmit delay between sending hello packets. Setting the hello interval to a smaller value can reduce the delay in detecting topological changes, but will increase the routing traffic. This value must be the same for all routers attached
