cisco supports multiple subnets on each interface with the 

interface config command

IP ADDRESS <address><subnet-mask> SECONDARY

We've had up to 4 subnets off a single interface with no 

problems.  There's no mention in the docs as to what
the maximum number that cisco supports.

IP devices on different subnets on the same interface will
use the cisco to talk to one another even though they
are on the same physical cable.  This is consistant
with the various Laws of the Universe that deal with
IP.
