From: Matteo Croce <mcroce@microsoft.com> commit ceed9038b2783d14e0422bdc6fd04f70580efb4c upstream. The multicast route ff00::/8 is created with type RTN_UNICAST: $ ip -6 -d route unicast ::1 dev lo proto kernel scope global metric 256 pref medium unicast fe80::/64 dev eth0 proto kernel scope global metric 256 pref medium unicast ff00::/8 dev eth0 proto kernel scope global metric 256 pref medium Set the type to RTN_MULTICAST which is more appropriate.
