Hi Yusuke, Thanks your answer. I know MPLS header total 4 byte, but MPLS label just use 20bit. Could you tell me in the ver1.3.2 spec, which section have specify OFPXMT_OFB_MPLS_LABEL must be 4 byte? The Wireshark can dissector my pcap file. I need strong reason tell my vender change them code. If you have time, please help check. Thank you very much.
