I donot think my test is wrong
when I test in icmpv6(RFC4443), I get failure in " Request send to
loopback address" section.
but I check the tcpdump message, I don't think my test is wrong. so who
can help me to get correct answer for the question:my link-local sent echo request to localhost,
and get echo reply. but TAHI need that echo request donot need get echo reply. please tell me why?
my tcpdump message:
