Cisco – Redistribute OSPFv3 static route to RIPng

I have a IPv6 static route on a Cisco 2600 that is being redistributed to other Routers in the same OSPFv3 area. One of the routers (not the one with the static route) is also a participant in a RIPng group. The OSPF routes are set to redistribute connected routes to RIPng, but the static route is not included in the redistribution. The border router that is connected to both areas has the static route as type OE2. Is there a command that I'm missing?

EDIT : I've created a diagram that shows a (simplified) topology of what I'm working with. We have a 6to4 tunnel between R1 and R5 (to traverse an IPv4 section of our network). Unfortunately, this link is treated as NBMA, thus static routes are required to establish the link between these two routers. The static route is defined at R1 (with redistribute statc on), visible through OSPFv3 on R2, but not being redistributed on R3 (even though all other learned routes on R2 ARE being redistributed).
