I have 2 nodes nodeA and nodeB I'm using tinc 1.1pre11 -- nodeA(fd80:2015:2105:abcd::1) :
$ ip -6 route fd80:2015:2105:abcd::1 dev tun0 proto kernel metric 256 fd80:2015:2105:adcd::/64 dev tun0 metric 1024 fe80::/64 dev eth0 proto kernel metric 256 $ ping6 fd80:2015:2105:abcd::1 PING fd80:2015:2105:abcd::1(fd80:2015:2105:abcd::1) 56 data bytes 64 bytes from fd80:2015:2105:abcd::1: icmp_seq=1 ttl=64 time=0.020 ms $ ping6 fd80:2015:2105:abcd::2 connect: Network is unreachable -- nodeB(fd80:2015:2105:abcd::2): $ ip -6 route fd80:2015:2105:abcd::2 dev tun0 proto kernel metric 256 fd80:2015:2105:adcd::/64 dev tun0 metric 1024 fe80::/64 dev eth0 proto kernel metric 25 $ ping6 fd80:2015:2105:abcd::2 PING fd80:2015:2105:abcd::2(fd80:2015:2105:abcd::2) 56 data bytes 64 bytes from fd80:2015:2105:abcd::2: icmp_seq=1 ttl=64 time=0.019 ms $ ping6 fd80:2015:2105:abcd::1 connect: Network is unreachable I can see in the debug output that the tinc daemons on each node is talking to each other. I suspect kernel having some internal settings as I don't see any debug message when I do a ping6 to the other node. If I change the ip -6 route on both nodes to /48 it works fine.
