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

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.
