Configuring DCC 709

Preparing to Configure

DCC

Determine the topology of DCC application

Determine which routers will provide DCC and the relevant communication parameters between the routers.

Determine the interfaces on the routers that provide DCC the functions carried out by each router.

Determine the transmission medium, PSTN or ISDN.

Prepare the data for DCC configuration

Identify the interface type (synchronous/asynchronous serial interface, ISDN BRI or PRI interface, AM interface, AUX interface) and configures the basic physical parameters on the interface.

Configure the link layer protocol (PPP, HDLC, Frame Relay or other modes) to be used on the dial interface.

Configure the network protocol (IP, IPX) to be used on the dial interface.

Configure the routing protocol (RIP, OSPF, or other protocols) to be supported on the dial interface.

Select a DCC configuration method (circular DCC or resource-shared DCC).

Configure the local parameters of DCC

Follow the configuration procedure to configure the basic DCC parameters according to the selected DCC configuration method, (circular DCC or resource-shared DCC) to enable the initial DCC implementation. Configure MP binding, PPP callback, ISDN caller identification callback, ISDN leased line, auto-dial, or a combination of these, in addition to the basic DCC configuration, if special applications are required. Alternatively, depending on the actual dialing link state the user can make an appropriate adjustments to the attribute parameters of the DCC dial interface.

Configuring DCC

Configuring DCC includes tasks that are described in the following sections:

 

Configuring DCC Prepared Parameters

 

Configuring Circular DCC

 

Configuring Resource-Shared DCC

 

Configuring MP Binding for DCC

 

Configuring PPP Callback

Configuring ISDN Caller Identification Callback

Configuring Special DCC Functions

Configuring Attributes of DCC Dial Interface

Configuring DCC Regardless of which method is used, circular DCC or resource-shared DCC, the Prepared Parameters following two basic DCC configuration tasks should be performed:

Configuring the mode of the physical interface

Configuring link layer and network and routing protocols on the interface
