sent in the IP source address field of the ping request. If this option is not specified,

(MTU).
You must configure MPLS at the
router or switch (the router or switch receiving the MPLS echo packets) to ping a Layer
2 circuit.
In asymmetric MTU scenarios, the echo response may be dropped. For example, if the
MTU from System A to System B is 1000 bytes, the MTU from System B to System A is
500 bytes, and the ping request packet size is 1000 bytes, the echo response is dropped
because the PAD TLV is included in the echo response, making it too large.
