[Babel-users] VPN Bridging with Babel

[Juliusz Chroboczek]

Is there an IPv6 link-local address on the tun0 interface?  Please show us
the output of

    ip addr show dev tun0

If there's no link-local address (Linux kernel bug), then you should add
one manually:

    ip addr add fe80::1/64 dev tun0

You should use different link-locals on the two sides of the tunnel
(e.g. fe80::1 on one side and fe80::2 on the other).
