Thanks! I was under the impression that, when you export an external route (OSPF) into level 1 only (to level 1) on L1/2 routers - this route will not be installed back into these routers - a sort of failsafe mechanism in ISIS for routes which do not have up/down bit set. But it looks like this is only when this same route is advertised to BOTH level1 and level2.
Setting up/down bit manually does make it easier...
