Hi,

FreeBSD 8.0 Release send two MLDv2 Reports at reboot before performing DAD for its Link Local address,
One for the IPv6 Solicited-node multicase address(i.e FF02::1:FFDB:ACD5) and other is unknown (i.e FF02::2:21d:d024 ).
Could anyone please clarify me, why FreeBSD is send MLDv2 Report for FF02::2:21d:d024 multicast address?

Please fine the attached ifconfig output and tcpdump trace captures and reboot time.

Let me know if your need more info

Thanks in advance
Sitaramaraju
