Disaster Recovery (DR) for F5 Devices in Bypass Restoration

What are the steps to take in case of an unforeseen 'disaster' to F5 devices? What can we do if, for example, the F5 device (F5 i5800 or C2400) and its peer are damaged at the same time? Is bypassi...

Hello, and thanks for your feedback. 

What external appliances that can act like a "bypass" and monitor links to F5 devices are you referring to? (i.e. switches, routers, firewalls)

Can an F5 L3 switch or router be used to replace both of the damaged F5 devices?

Or could you suggest any other way to solve the issue aside from RMA?

Thanks.

I'm referring to TAP bypass appliances, for example like Garland.

This will work pretty good when there is no NAT and your F5 is proxying something using the same IP address of the service, for example if you run a WAF. In this case when F5 is down TAP will forward traffic downlink and your routing processes will forward it to destination without packet loss. 

 

Again, I think we need better context, for example if you rely on NAT and if virtual address IP's only exist on F5 TAP won't really do much and you still need to plan where to send this traffic when a disaster manifests.
