IPv6 routing question

I just noticed this in my /var/log/messages:

Oct  9 20:57:35 set dhcpcd[1193]: wm0: changing route to
fdc7:8cef:197:1::/64 Oct  9 20:57:35 set dhcpcd[1193]: wm0: expired

Deleting the route and then adding it back again every half hour? The
DHCP server is just a little old Linksys consumer router. Do I have
something misconfigured? Or do I just need a new router because this
one is buggy or obsolete?
