OSPF adjacency over Token to Ether bridge

I am working on lab 5 in my make-shift lab. Most of my routers have token
ring, but a few are ethernet, to overcome this obsticle I have all the token
interfaces connected to a 7500 (R7) and all the ethernet interfaces
connected to a 2924 (SW0). The 7500 also has connections to the 2924. In
order to get the topology I need I am using the 7500 to bridge between token
and ethernet. I have that much working, I can ping from the ethernet to the
token interface, but I can't get OSPF to come adjacent. I suspect there is
an issue with translating multicast traffic from token to ether. Does
anyone know what might be the problem?
