The RTA_SRC attriute matches on sutrees in the ipv6 routing table:

ip -6 r a default via fe80::1 dev eth0 from 2000::/64
ip -6 r a default via fe80::2 dev eth0 from 2000:1:/64

ip -6 r g :: from 2000::
ip -6 r g :: from 2000:1::

...should return different routes. The from parameter is the RTA_SRC
attribute.

Greetings,

  Hannes
