I have recently acquired a Cisco 1601R router and I'm trying to configure ISDN dialup access to my ISP. It has an ISDN WIC card fitted and I am not using the Serial port at all.
My ISP provides dynamic IP addresses for dialups and it isn't possible to get a fixed IP. The IOS version on the router is 11.2 and it doesn't appear to support the IP ADDRESS NEGOTIATE command.
Does anybody have any idea how to set up the IP negotiation so that the router can pick up the IP address each time it dials the ISP?
