You also want to make sure the switch that router port is attached to supports a larger Ethernet MTU. Also, setting your MPLS MTU to at least 1526 (depending on whether you are doing vanilla MPLS or AToM as well, e.t.c.) would help. I faced the same issue with a box connected to a 2950 Catalyst switch (supports only 1500 bytes MTU) with MPLS enabled. Granted, I was running 12.3(20) at the time. Cheers, Mark.
