I'm new to firewalls but have an FWSM configured (Visio and config attached). I would like to code OSPF between the FWSM and my internal network and wanted to make sure that this is doable from the FWSM viewpoint. Also, I would like to have the 'vendoroutside' connection be redistributed into my ospf so that i can route to a different firewall if their link goes down. They own the router within our network and they would install a 2nd router in one of our remote offices. Can you tell me if this will also work? Would they be able to use OSPF or would we need to use BGP?
Thanks for any help you can give (and forgive my ignorance)

FWSM and OSPF routing
