We have a few servers colocated at a hosting facility, behind a pair of ASA 5510s. The facility has advised us that we will be moved from a switched to a routed port, and we need to install our own switches between their new routers and our ASAs. The switches are to allow HSRP broadcasts between their redundant routers.
Our ASAs are active/standby pair. We're worried that by adding the new switches we'll introduce more points of failure than we'll remove. What's the optimal configuration in this setup? We have nothing fancy behind the ASAs, only a pair of switches and a few servers, all on a single subnet.
