[c-nsp] Cisco ASR as BBRAS... ? (is this a sane solution)

I think, ASR quite good solutoin for your case because ERX is too big and too expensive for 2K subscribers.
Planing inmplementation you should remember that you need ISG for CoA support and your Radius servers should support Cisco AVPairs for service activation.
