Perry noticed some routing problems recently, and on investigation, I
found several sites I was unable to reach, including www.netbsd.org,
www.ipv6.org, and several sites in Japan, as well as 6to4 (2002::/16)
sites in general. These aren't 6bone allocations, they're sites with
the newer 2001::/16 block allocations given to "real" IPv6 registries
(as opposed to the "test" allocations on the 6bone).
The guy maintaining MERIT's 6bone router says they're looking to
decommission it sometime soon; I've just replied asking if they've got
a specific timetable. At some point, we're going to have to switch the
limekiller tunnels over to the new address allocation we should be
receiving very soon. Exactly how that's going to work, and how much
SIPB and limekiller will be involved, I don't know right now.
Once the campus IPv6 upgrade is online, and until the transition is
done, I think it's safe to say we'll be trying to share routes between
limekiller's 6bone setup and the main campus routers, so that should
significantly improve our connectivity for a while.
In the meantime, I've reconfigured our BGP server to start exchanging
route information with VBNS, and that's filled in a lot of the gaps I
noticed while looking into Perry's problem, although we still don't
have a working route to 6to4 sites at the moment. If that's an urgent
problem for anyone (and I've heard no specific complaints on it so
far), I've got a couple of 6to4-capable machines off campus that I
could set up as routers fairly quickly, but I'd prefer to wait until
some of the hardware for the campus IPv6 upgrade is ready.
