Is this correct procedure?Nope. In their infinite(simal) wisdom the architects of IPv6 determined that a host configured with both a global scope IPv6 address and an IPv4 address will attempt IPv6 in preference to IPv4. If you configure IPv6 on a LAN without first installing your IPv6 Internet connection, that LAN will break horribly.
The default is to tune for IPv6 first but it been configurable for years now. Given one generally wants to use IPv6 over IPv4 to avoid having you packets going through CGN boxes this is a good thing for you and your ISP. As for "breaking" your LAN, if the applications take 60 seconds to fallback to the other address they were already broken. Go complain to your application vendor. Some vendors have already fixed this problem with their applications.
Work your way from the outside in: start with BGP, then the interior routers and configure the LAN last. Regards, Bill Herrin -- William D.
