DHCPV6 Interface Issue with Solaris

Fri Aug 19 16:27:46 UTC 2011

I have a working DHCPv4 configuration on Solaris which I'm slowly trying
to replicate in a DHCPV6 environment.  I say slowly, because the

V4 conf file makes extensive use of classing using both V4 options 43
and 60.  Since neither classing (nor pools for that matter) are
supported

yet in Version 4.2, I've simplified the V6 conf file, approaching this
in "baby step" fashion.   I'm at the point where the DHCPv6 server just

cannot figure out that it should be listening on a interface I want it
to.   This interface has a Link Local address and a sub-interface I
configured

using what Solaris terms a "IPv6 Token".  The IPv6 token is just a user
specified 64 bit interface ID used during autoconfiguration.  Below are

the particulars.  Any insights to this issue would be greatly
appreciated.
