We need to implement a dual firewall (ASA’s) solution to provide some connectivity between 2 separate Networks that are in the same physical location. Each firewall will have an interface connected to a switch. The switch will be configured with two layer-2 VLAN’s, and each firewall interface will serve as the Layer-3 for the VLAN.
Just to give you an idea, clients on VLAN-20 will need access to resources on Network-B, but they will not have access to Network-A. Clients on VLAN-10 might need access to both Networks.
I just can’t figure out the best way to route the traffic between all of these networks. I will have to add static routes on Network-A Core since it doesn’t run any routing protocols, which is fine. I am just trying to figure a way to run a routing protocol for the rest of the setup. The switch where the firewalls are connected to is a Layer-3, and will be able to run BGP,OSPF, etc. I have the ability if I want to run BGP and neighbor the router on Network-B, but I just can’t figure out how to extend the routing to the ASA’s.
I know this sound confusing, but hopefully you get the idea.
Your input will be much appreciated.
