In Cisco language, this is called "Local Switching" (see
http://www.cisco.com/en/US/customer/docs/ios/12_0s/feature/guide/fslocal.html).

There is a vast number of restrictions on this feature. If it fit your
needs, you're a lucky one :) Personally, I'm very much miss "Vlan to
Vlan different interfaces" on GSR, but it's at least supported on IOS
XR (though undocumented).
