Clarification w.r.t MDLv2 reports send at reboot in FreeBSD 8.0 Release

[SitaRamaRaju Kunparaju]

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
