It's 1103 and this is us, surfnet. I contacted Itojun offline because
we are not announcing the prefix to 3274. We also do not see 2001::/16
in our routing table. We don't see the route, Itojun still does. Could
the other ASes in the path below have a check? I suspect it is a buggy
BGP implementation somewhere which is holding the route.
