Configuring DCC 717

By default, circular DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other interfaces (serial, asynchronous, AUX, etc.) and the user should manually configure the dialer enable-circularcommand. In addition, when no dialer interface is created, the physical interface does not belong to any dialer circular group, and the default priority is assigned to physical interface 1, and this is added to a dialer circular group.

Configuring multiple interfaces to receive calls from multiple remote ends

Perform the following configuration steps after the basic DCC configuration is implemented. As shown in Figure 231, multiple local interfaces receive calls from multiple remote ends (the picture components of inverse color represent the routers irrelevant with the networking):

Figure 231 Multiple interfaces receiving calls from multiple remote ends

		if1	Remote end A
			Single/Multiple interface(s)
	if0	Router
		if2	Remote end B
Local end	if1
(Multiple interface) Router		if3 Router	Single/Multiple interface(s)
	if2
		if4	Remote end C
		Router	Single/Multiple interface(s)

As shown in Figure 231, the local interfaces interface1 (if0), if1, and if2 receive DCC calls from the remote interfaces if1, if2 and if3. Since the local end is multiple interfaces, the dialer circular group must be used to configure DCC. The user can select to configure either PAP or CHAP authentication.

Use the local-user password command to configure the user name and password permitted to dial in system view, and perform other configurations in dial interface (physical or dialer interface) view.

By default, circular DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other interfaces (serial, asynchronous, AUX, etc.) and the user should manually configure the dialer enable-circularcommand. If no dialer interface is created then by default, the physical interfaces do not belong to any dialer circular group.
