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
Prepared Parameters Regardless of which method is used, circular DCC or resource-shared DCC, the
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
