Having multiple IPv6 subnets on the same wire is asking for trouble. For example, I believe an ICMP redirect still (in 9.1) does not create a temporary route: http://www.freebsd.org/cgi/query-pr.cgi?pr=152791 which beat us hard time (random unreachability between hosts), having to rearrange that legacy segment which happened to have two subnets on the same wire. The static routes destinations must be directly reachable (on-link). Either use a single /56 for the whole LAN, adjusting the prefix length on each interface, or provide a router within each subnet. Doing otherwise (like using static ndp/arp entries) is just a hack.
