Applies To: Windows Server 2008 R2

A demand-dial interface is a logical interface that represents a point-to-point connection. The point-to-point connection is based on either a physical connection, such as two routers connected over an analog phone line that uses modems, or a logical connection, such as two routers connected over a virtual private network (VPN) connection that uses the Internet. Demand-dial connections are either on-demand (the point-to-point connection is only established when needed) or persistent (the point-to-point connection is established and then remains in a connected state). Demand-dial interfaces typically require an authentication process to become connected. The equipment required by a demand-dial interface is a port on a device.

Verify
If the calling router uses a dial-up connection to the local ISP, the local ISP assigns the router a temporary IP address. You can confirm that this IP address exists by typing ipconfig at a command prompt.
To perform the following procedure, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.
To check the status of the demand-dial interface:
- Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
- In the console tree, click Network Interfaces.
- In the details pane, in the Connection State column, verify that the demand-dial interface that matches the user name for the credentials of the calling router is connected.
