Hi, Ah the problem seems to be that for some reason Linux elects a link-local address for the ping, which is of course due to the fact, that there is no global address assigned to the interface and that the hop limit seems to be set to short (it is 1). So I did the following
sudo ip route add ff1e::/16 dev tap0 table local # add routing entry for ff1e::1 sudo ip addr add affe::dc53:7dff:fe99:516e/64 dev tap0 # add global unicast address for tap0 ping6 -t 2 ff1e::1 # ping with hop limit 2 Now I get one reply back, and if you add affe::/64 to the fib of the border router the ethos interface (wasn't able to test that) it should work.
