Dynamic routing alternative between ASA and edge routers?
This is the current setup between two edge routers and an ASA 5580. The edge routers carry approximately 9200 BGP routes with ISP A also supplying the default route. Is there a good, i.e. has been successfully implemented, dynamic routing situation between the edge routers and ASA such that the ASA can send traffic to the particular edge router that carries the best specific route?
Let's remember that the ASA was built as a High-Level Next Generation Firewall.
That does not mean it's not useful for routing but here we are talking about thousands of routes, I do not think there will be a performance issue on the FW because of that. I mean you have one of the greatest Cisco Firewalls (functionality and power speaking).
So if that's the case and you really want to do that you will need to implement either RIP,EIGRP,OSPF on the link and then do the redistribution on the routers.
