Configuring an interface to place calls to a remote end

In Figure 40, an interface at the local end places calls to a single remote end (the components in inverse color represent the routers irrelevant to the networking).

Figure 40: Network diagram

In this scenario, for interface if0 to place DCC calls to a single remote interface if1, you can configure a dial string with the dialer number or dialer route command. As calls are to be placed from a single interface, you can configure DCC by configuring a dialer circular group. In addition, you can configure PAP or CHAP authentication.

To configure an interface to place calls to a remote end:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter dialup interface (physical or dialer interface) view.	interface interface-type interface-number	N/A
3. Enable C-DCC.	dialer enable-circular	By default, C-DCC is disabled.
4. Configure a dial string for calling a remote end.	dialer number dial-number dialer route protocol next-hop-address [ mask network-mask-length ] [ user hostname \| broadcast ] * dial-number [ autodial \| interface interface-type interface-number ] *	Use either command.
