Cisco 1601R IOS11.2 IP Negotiation problem

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?

Thanks guys,

M

I haven't tried it on a BRI interface, but what about "ip address dhcp"?

Thought of that one but it's not listed. Presumably, it isn't supported under IOS 11.2

Hate to tell you Mike,
You are one revision to early:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios113ed/113ed_cr/dial_r/drprt11/drezip.pdf

"Usage Guidelines
This command first appeared in Cisco IOS Release 11.3.
Use the ip address negotiated interface command to enable a Cisco router to automatically
negotiate its own registered WAN interface Internet Protocol (IP) address from a central server (via
PPP/IPCP) and to enable all remote hosts to access the global Internet using this single registered IP
address."

This PDF is Cisco's "EasyIP" Dial solutions - it may give you some further insights/ideas.
You will need to upgrade the IOS. Sorry

Thanks a mil Whippy...

You've just confirmed what I suppose I've known all along. No big surprises there.

At this stage, I'm kinda resigned to the fact that I'll have to upgrade the IOS anyways - might as well go 12+ and I'll get NAT as well.

Any idea where IOS upgrades can be purchased from or do they have to come directly from Cisco?

Cheapest place to get IOS is from Ebay
you can get second hand cd's, other wise you have to goto Cisco / a reseller.
Good Luck.
