I think this http://www.gossamer-threads.com/lists/nsp/ipv6/13537 may answer some of the questions on how to make it work correctly. I like the fact the 6to4 gateway should be on a separate machine that BGP with the main router. If the gateway dies, the routes are withdrawn and clients go and look for another gateway somewhere else.... ----- Original Message ----- From: "Jeroen Massar" <jeroen () unfix org> To: "Mitchell Warden" <wardenm () wardenm net> Cc: nanog () nanog org Sent: Tuesday, 31 August, 2010 6:46:52 PM Subject: Re: Comcast enables 6to4 relays On 2010-08-31 08:22, Mitchell Warden wrote: [..]
Is there a reason not to advertise more specific prefixes from 2002::/16 to ensure that traffic for your v4 routes comes back to your own 6to4 router? If for example all my users have v4 addresses in 192.0.2.0/24, I could advertise 2002:C002:0000::/40 instead of or in addition to the full 2002::/16.
The RFC forbids that with a good reason, as then we'll end up importing the IPv4 BGP table into IPv6... not something we want to see (unless one loves to import 300k routes in there, I guess people will really start whining about that though ;). Greets, Jeroen
