Do you have the ability to see the DWDM stats? Is the 10G interface configured to drop when wavelength goes down?
We need to figure out if the DWDM equipment, the actual fiber connection, or the router interfaces is the issue here. I'll bank initially on a problem with the DWDM based connection - any other wavelengths going down or can you tell us?

DOWN to UP state takes 5 second most of the time, just wondering what could be causing this.
