Disaster Recovery (DR) for F5 Devices in Bypass Restoration

lttarvina In the unlikely event that both F5 devices fail at the exact same time in your HA cluster and they are configured to be in path the only device that can realistically be swapped to just allow routed traffic to get back and forth would be a router or an L3 switch configured to route traffic between the two or more subnets that the F5 was routing traffic between. If you had a router in front of and behind the F5s already I would imagine you could have an additional path that goes around the F5s and utilize SLA monitors to change routes to the bypass if the F5 floating IP doesn't respond to the SLA. This seems like an edge case that you are attempting to solve for because any device in HA that would have both devices fail simultaniously is most likely having a larger issue in that region or would require 1 of the 2 failed devices that failed to be replaced anyway. You might consider having a single F5 for each device type as a backup so that you can restore the configuration and put that extra device into production and wait on an RMA for the failed devices.
