   I went through the change history and noticed I made the
   following changelist for IPv4,=20

http://svn.freebsd.org/viewvc/base/head/sys/netinet/in.c?r1=3D201811&r2=3D=
20
3401

   Maybe related and something similar needs to be done for IPv6 ...

  Nothing obvious comes to mind at the moment.

  That explains the errno =3D 47, EAFNOSUPPORT.

  I also noticed in your routing table output that all of entries
  that have junk are related to the ng interface.
