Do you receive those prefixes over RA or manual config?
Is forwarding enabled? What does the ra_accept sysctl say?

Also 'ip -6 ro get <prefix>' can be very useful to check where the
routing table thinks packets are supposed to go.

In general on a Linux install from the last decade or so, avoid
'netstat' and 'ifconfig' and use iproute: 'ip ro sho' or 'ip -6 ro sho',
'ip -6 addr show'
