I realise this is a possibility, but shouldn't there be a mention in the draft of recommended mechanisms to achieve this goal? >> In the case of getting address using DHCPv6, there is also no direct >> connection between the default route and the SA, as the DHCPv6 server >> might be different from the default-route gw? > > Does the DHCPv6 response contain any information about the DHCP-relay used? If the DHCPv6 server is just local to the network and doesn't use a relay? Afaik there has been a deliberate decoupling of stateful DHCPv6 and SLAAC so as to make DHCPv6 not able to hand out a default routes, so I don't really see how this coupling can be done again with the basic mechanisms available today? In v6ops I was pointed to BRDP <http://tools.ietf.org/html/draft-boot-brdp-based-routing-00> which is an expired draft, I believe a mechanism like this is needed to properly achieve the goal of correct default route for certain SA. I don't really see how it can be done otherwise. -- Mikael Abrahamsson email: swmike@swm.pp.se
