single B channel or two B channels, substituting the correct addresses and host names as
appropriate for your network:
Enter privileged EXEC mode:
Step 1
Router> enable
password: enablepassword
Enter the configure terminal command to enter global configuration mode.
Step 2
Then enter the host name of the current router, the user name of the target router
(the router to which packets will be sent), and the password that the routers will
use for CHAP caller identification. The user name and password are case
sensitive and must match the host name and password of the target router (even
if it is not a Cisco router):
Router# configure terminal
Router (config)# hostname currentrouter
Router (config)# username targetrouter password abc
Enter the isdn switch-type command to configure the ISDN switch type (such
Step 3
as basic-5ess, basic-dms100, or basic-ni1). Refer to Table 4-1, earlier in this
chapter, for a list of ISDN switch types supported.
Router (config)# isdn switch-type switch-type
Step 4 Configure the IP address and subnet mask for the LAN interface:
Router (config)# interface type port_number
Router (config-if)# ip address ipaddress subnetmask
Configure the IP address and subnet mask for the BRI interface:
Step 5
Router (config-if)# interface bri port_number
Router (config-if)# ip address ipaddress subnetmask
