Configuring Demand-dial-Routing

Demand-dial routing is used most often when the expense of providing a dedicated link between two remote routers is prohibitive, or when the connection is not used frequently enough to justify the expense of a dedicated line.

Configuring Demand-Dial Interfaces 

• The first step in deploying demand-dial routing is to configure a demand-dial interface on each computer you want to function as a demand-dial router.         
• You can configure these interfaces by using the Demand-Dial Interface Wizard. You can run this wizard as an extension of the Routing And Remote Access Server Setup Wizard, or as an option after the Routing And Remote Access service has already been configured and enabled.
•          If you have previously configured and enabled the Routing And Remote Access service without demand-dial functionality, you must enable this functionality before you create any demand-dial interfaces.   
• You achieve this task by selecting the LAN And Demand-Dial Routing option on the General tab of the Routing And Remote Access service properties dialog box, as shown in Figure

• Once you have enabled demand-dial routing, you can launch the Demand-Dial Interface Wizard by right-clicking the Network Interfaces node in the Routing And Remote Access console tree and then clicking New Demand-Dial Interface. The wizard allows you to configure the basic features of the interface.

Shortcut Menu Commands

•  The shortcut menu commands for each demand-dial interface are those that appear when you right-click the interface in the details pane of the Routing And Remote Access console.

• The interfaces themselves appear in the details pane when you select the Network Interfaces node in the Routing And Remote Access console tree.

The following list describes the four commands that are unique to the demand-dial

interface shortcut menu:

■Set Credentials Allows you to configure the user name and password that the interface uses when it connects to a remote router.
