I just upgrade two of my 1760's with the c1700-y-mz.122-11.YV.bin ios. Roughly about the same time, both sites went down, but the interfaces said UP/UP and the PVC and DLCI's were active, but unable to pass any traffic. I called our service provider, and they were seeing the traffic coming in from the host, but no replay from the remote side ( being the 1760 ). After reloading the router 3 times, and unable to get the PVC to pass traffice, I down graded the IOS to 12.2.4.YN, and reloaded the router and was able to pass traffic. I am just wondering if any one else has had this problem, or is it a bug in the IOS. I do understand that this is still in development release.
