My WAN connection is going through a private MPLS network. My layer 3 core switch is BGP peering with my ISP CE router. My core is also connecting to a FW for the backup internet. I am using 2 floating static default routes with higher AD route next-hop to the FW.
Now I am in the process of adding a router to the setup. So the router will take the function of the WAN router. BGP peering from the core will be moving to the WAN router. I am thinking of configuring OSPF between my WAN router and my core switch. So my questions are:
- Should I redistribute BGP into OSPF on the WAN router? My WAN is using MPLS VPN so I only see the routes from my remote sites via BGP.
- If redistribution is necessary, will my failover with the floating static default routes still work?
- If I don't redistribute, how will this whole thing work? Will it work?
