RE: DHCPv6 - does it have gateway option

2007-09-18 Thread Leino, Tammy
I had this same discussion with the DHCP working group a few weeks back. The end result was that there should always be an IPv6 router on-link configured to transmit RAs. They could not fathom why an IPv6 network would not have an IPv6 router on-link. That is why there is intentionally no DHCPv6

2007-09-18 Thread Ralph Droms
Well...I have to respectfully disagree about the reasoning behind the decision. There is no IPv6 default router option in DHCPv6 because that information is given to hosts in RAs. The assumption is that, if there is a router willing to act as a default router on a link, it's presence
