Re: dwdm and routers

By a customer we had to put 2 ISL between 2 3900 linked with a 1 GB bandwidth DWDM, and the only way to do it was to to let the auto-speed. It never worked by setting the speed at 1 GB. But even now, each time the line are reset on the DWDM, it takes up to 10 minutes for the 2 ISL to come up... Don't know why... Much errors before the lines comes up, but then it works fine without errors.
