Comment (by markzzzsmith@…):
I don't think it should be necessary to create custom on-link routes. The
/64s on-link routes should be created automatically when then the address
is configured with a prefix length of /64. e.g,
root@OpenWrt:~# ip -6 addr add fd0f:f1b5:2af:ff00::1/64 dev br-lan
root@OpenWrt:~# ip -6 addr show dev br-lan | grep fd0f:f1b5:2af:ff
inet6 fd0f:f1b5:2af:ff00::1/64 scope global
root@OpenWrt:~# ip -6 route show | grep fd0f:f1b5:2af:ff
fd0f:f1b5:2af:ff00::/64 dev br-lan proto kernel metric 256
root@OpenWrt:~#
Not specifying the /64 on the address seems to make the 'ip' tool assume a
/128 (which I think is reasonable), could that be why people think
automatic creation of the corresponding /64 on-link route is broken in
prior versions of Linux?
