 Hello,

 is it possible to do 'mpls l2transport route x.x.x.x yy' for ethernet
on two interfaces of the same PE?

Thanks

John

The feature you are looking for is called "Layer 2 Local Switching" and
is available in 12.0(27)S on c7200 and c7500 (see
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft
/120limit/120s/120s27/fslocal.htm). It is not available in 12.3
mainline.
