MIG-29A BVR - how to force enemy aircraft down low?

[The Gryphon]

Hi guys, I was watching this excellent video how sneak up on enemy aircraft 

But what if the enemy aircraft is really up high, perhaps at 20 000 - 30 000 feet, how do I force them down below 15 000 feet? Or how can I sneak up on a enemy aircraft operating at high altitude without being detected on his radar?

Sta low and come up behind him or from his 9 '0 clock where his radar can't see you?
