Thank you John.
Has your working group considered adding this as a DHCPv6 option?
If the on-link router is not configured to transmit RAs, a DHCPv6
option advertising the default gateway would be helpful in
populating the routing table.

Hello Hemant,
There is no DHCPv6 mechabism to explicitly transmit router/gateway
information.

Subject: prefix length determination for DHCPv6
Hello,
In implementing RFC 3315, I see no option or field in the IA_NA option
for a prefix length associated with an assigned IPv6 address. How
does
the client determine the prefix length of the IPv6 address the
server is
assigning?
<hs> One way to to send a Prefix Information Option (PIO) for the
assigned address prefix in RA to the client. PIO includes prefix
length.
</hs>
Furthermore, in the absence of a configured IPv6 router on the
link, can
the client use the DHCPv6 server to find a default gateway out of the
local network?
<hs> I don't believe so. I'll let the DHCPv6 RFC authors like Ralph
Droms and Bernie Volz verify this one.
</hs>
Hemant
If so, what RFC specifies this option?
Any help or referrals to additional RFCs would be much appreciated.
Best Regards,
Tammy Leino
