If NS received then send NA, and wait Echo Reply again 5. Receive Echo Reply 6. repeat from 1 to 5 (with increase Next Header value). last Unrecognized Next Header packet is: IPv6 Header Version = 6 Traffic Class = 0 FlowLabel = 0 PayloadLength = 8 NextHeader = 60 (Destination Options) HopLimit = 64 SourceAddress = Tester Link Local Address DestinationAddress = Target Link Local Address Destination Options NextHeader = 136 - 254 (be increased for each packets.)

FAIL : don't received ICMP Error message or Echo Reply. =cut # =head1 REFERENCE # # RFC2460 # # 4. IPv6 Extension Headers # # If, as a result of processing a header, a node is required to proceed # to the next header but the Next Header value in the current header is # unrecognized by the node, it should discard the packet and send an # ICMP Parameter Problem message to the source of the packet, with an # ICMP Code value of 1 ("unrecognized Next Header type encountered") # and the ICMP Pointer field containing the offset of the unrecognized # value within the original packet. The same action should be taken if # a node encounters a Next Header value of zero in any header other # than an IPv6 header. # =pod =head1 REFERENCE =begin html
