We have two 6509 on the inside network hooked to our two asa fiewalls configured as primary and back up. Then both of them are hooked to a cheap network switch and then connected to our ISP's router. Is this best-practice or what is the best way to do this? Could we create a non-routed vlan on our cores 6509's and hook one up to one asa to one 6509 and the other asa to the other asa? Then hook the ISP router to one of the 6509's. The problem I see with this is that if the 6509 that the ISP router is hooked to goes down then the internet is down. Looking for suggestions and ideas to make our current design better. thanks in advance
I have this problem too.
