If doing tag1 to tag2 translation as suggested, only need to do it on one interface. Whatever is specified on an interface will be performed on input while the opposite will be performed on output. Using pop on both interfaces, as suggested in my other reply, is more straightforward but is less efficient as VTR operation is performed on each packet twice.

Hi, I have a L2 cross-connect configuration where packets arrive on a sub-if1 (with vlan id 500) and go out on sub-if2 (with a vlan stack 200, 150). When I send packets on sub-if1, it is getting out on sub-if2, but the vlan tags are not getting re-written. Is there anything else that should be done or is this the standard behavior? Thanks, -nagp
