Chapter 3 Configuring with the Command-Line Interface
Configuring ISDN BRI WAN Interface Cards
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:
Connect a console to the router.
Power on the router.
Command Purpose
Step 1
Router> enable
Password: password
Router#
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
Router#.
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router(config)# isdn switch-type basic-5ess
Enter an ISDN switch type. See Table 3-5 for a list
of ISDN switch types.
Note Switch types configured in interface
configuration mode override this setting
for the configured interface.
Step 4
Router(config)# ip routing
Router(config)# appletalk routing
Router(config)# ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 5
Router(config)# interface bri 0/0
Router(config-if)#
Enter the interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 6
Router(config-if)# ip address 172.16.74.2
255.255.255.0
Router(config-if)# isdn switch-type
basic-5ess
Assign the IP address and subnet mask to the
interface.
If you are configuring this interface for voice,
enter the switch type instead of an IP address.
Step 7
Router(config-if)# appletalk static
cable-range 5-5
Router(config-if)# appletalk zone ZZBRI
Router(config-if)# ipx network B004
Router(config-if)# isdn incoming-voice modem
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.
If you are configuring this router for voice, use the
isdn incoming-voice modem command.
