Now Russia is essentially limited to operating internally along with international connections to the likes of China, DPRK and Cuba (though how they get to the latter without flying through airspace closed to them I can't readily see!) they ought to have plenty of grounded western equipment which they could cannibalise to keep a core fleet in the air, and that's before they start thinking about bringing 134s, 154s and IL62s back into service - supposing there are that many still extant that could be brought back to operational condition.
(OK I don't know if any of the former USSR nations - e.g. Kazakhstan, Turkmenistan, etc. have banned Russian airlines)
