It happened again, this time in a slightly more convoluted scenario
with bgpd adding and removing routes. I grabbed the output of route
monitor from the time the tap0 interface was started, so it's quite big
:(
I've uploaded two versions, one with IPv4-addresses removed [0], one
with the addresses still in, in case I messed something up [1]. The
routing table looks like this (routes added by bgpd disappeared because
the session died after the broken route was added):
$ route -n show -inet6

As before, if you need any more info or pcaps or anything, I'd be more
than happy to assist.
