If a sender binds to a particular NIC (SO_BINDTODEVICE), the outgoing traffic is being sent via the first found. The bonded device is thus not taken into an account during the routing. From the ip6_route_output function: If the binding address is multicast, linklocal or loopback, the RT6_LOOKUP_F_IFACE bit is set, but not for global address. So binding global address will neglect SO_BINDTODEVICE-binded device, because the fib6_rule_lookup function path won't check for the flowi::oif field and take first route that fits.
