Configuring ISDN BRI WAN Interface Cards
You can configure the interfaces on your BRI WAN interface card manually by entering Cisco IOS
commands on the command line. This method, called configuration mode, provides the greatest power
and flexibility.
Timesaver
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall
process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN connection on
both ends and the router does not have a valid configuration file stored in nonvolatile random-access
memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the
router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet
Protocol (TCP/IP) host.
Before you begin configuring the BRI interface, make sure you:

Chapter 3 Configuring with the Command-Line Interface
Purpose
Enter the interface configuration mode and
specify the asynchronous interface to configure.
You have entered interface configuration mode
when the prompt changes to
Assign the IP address and subnet mask to the
interface.
Configure routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example,
AppleTalk and IPX are being configured on the
interface.
Configure asynchronous parameters according to
your needs.
Return to the global configuration mode and
repeat Step 4 through Step 7 if your router has
more than one interface that you need to
configure.
Return to enable mode.
