The IS-IS support has nothing to do with the ASICs, both IS-IS and OSPF
are done in software (the hardware just needs a suitable filter to punt
the interesting packets to up to the processor).

Business reasons - Cisco knows they can get away with charging more for
equipment which can switch packets in hardware and run IS-IS, so they do.
