In my trace file (created by tcpdump -w), there is an ICMPv6 Echo Request sent
to the IPv6 multicast address FF02::FB contained in a conventional Ethernet
frame with destination MAC address 33:33:00:00:00:fb. Wireshark labels this
(incorrectly) as IPv6-Neighbor-Discovery_00:00:00:fb. The packet is indeed
IPv6/ICMPv6, but it is not a neighbor discovery (it is an Echo Request). The
URL associated with this report is the trace file.
