In a switched environment, you run into the problem of a source MAC coming
from more than router, so you need to have different local MACs mapped to
the destination MAC.
I suggest you read:
http://www.cisco.com/en/US/products/sw/iosswrel/ps1830/products_feature_guide09186a00800c75bd.html
to understand more about this as not knowing what you are configuring is a
hazard.
