Configuring
ISDN If you have an ISDN BRI WAN module, configure the BRI port for
ISDN. This section explains typical ISDN configurations for one or
two B channels. In the examples, the BRI port is configured for IP
routing and Point-to-Point Protocol (PPP) encapsulation.
Complete these steps to configure the router for a basic ISDN PPP
connection on a single B channel or two B channels, substituting th
correct address and host names as appropriate for your network.
1. Enter enable mode:
Router> enable
Password: enable password
2. Enter the configure terminal command.
Router# config term
3. If you have not already done so, enter the isdn switch-type
command to configure the ISDN switch type:
router (config) # ISDN switth-type switch-type
4. Enter the BRI interface, encapsulation method (PPP), authentica
tion type, target router’s IP address and ISDN number to dial, and
the dialer group number:
Router (config) # interface bri 0
Router (config-if) # encapsulation ppp
Router (config-if) #ppp authentication chap
Router (config-if) # dial map ip targetrouter_ipaddress targetrouter_phonenumber
Router (config-if) # dialer-group groupnumber
Do not use periods or hyphens when you are entering dialing num-
bers.
Note: The ISDN/BRI interface provides dial backup for the
AI2524 card. When a connection is requested, the system
checks the username presented for validity, then dials
back the number associated with the username.
