Narrative:

Climbing to our cruise altitude we were told to cross 13 mi north of alo at a specific altitude, which our airbus 320 computer said we would comply with. I was distracted within the cockpit and we crossed the point about 400 ft low and were advised by ATC of this and that opposite direction traffic was the reason for the restr. I won't trust the computer so much next time and will pay more attention!
