Hi, Xiaodong IXIA test RFC 2460 4.5section https://www.rfc-editor.org/rfc/rfc2460#section-4.5
the software will send two packet, software configure MTU is 1500, and it will send two 768 size icmpv6 request fragment packet it expect receive two reply packet centos7 can receive two packet, but when receive the first packet it will reply a packet (wireshark show "parameter problem erroneous header field encountered") so i think if centos7 no support this function IXIA show send two packet but not receive two expected packet If there has a ipv6 configure in system i dont know, thank you Best regards wanghe
