I have one Cisco gear (7204-VXR NPE-300)used to terminate around 1500 PPPOA and PPPOE ADSL customers, but Decide to replace it by Cisco7206-VXR NPE-G1 for more bandwidth and sessions, but we faced a very weird behavior, the customers login and authenticated with the Radius but they assigned the same IP address!!!!! and there is nothing wrong appears on the Radius log, so any advice??
Note: i had change the IOS to different releases
