After that, "ip -6 route flush cache" actually succeeds in removing the rou= te via default gateway, and I then get the proper route entry: root@neru:~# ip -6 route get fd39::100 fd39::100 from :: via fd39:20::39 dev tun-rm src fd39:20::3 metric 0=20 cache So I conclude that my issue is very similar to [1] mentioned in a Bugzilla entry [2] linked here just today.
