How do I configure an ISDN connection on my Cisco router for Internet connection?
How do I configure an ISDN connection on my Cisco router for Internet connection? What information do I need to know from my ISDN provider? Could you give me a detailed configuration?
From your service provider, you need to get the switch-type, ISDN number, IP address, subnet mask and default gateway for your router. Also ask them if you need to configure the static route on your router.
A generic BRI configuration is detailed below. But use it with caution until you understand each of the commands.
IP address negotiated (can give the static one also)
ISDN switch-type basic-net3 (check with ISP)
no CDP enable
dialer remote-name ISP
dialer idle-timeout 180
dialer string 1234 (check the string)
PPP authentication chap pap calling
