What is the altitude separation minima between non-RVSM and all other aircraft at or above FL290?

RVSM airspace lets properly equipped aircraft keep 1,000 ft vertical separation between each other from FL290 to FL410. When one aircraft is non-RVSM (not meeting those standards), the safety buffer has to be larger, so the separation from any other aircraft at or above FL290 is increased to 2,000 ft. This compensates for the less precise altitude-keeping and equipment, maintaining safe spacing. So the minimum altitude separation between a non-RVSM aircraft and all other aircraft at or above FL290 is 2,000 ft.
