I work in a very small software development team where we (just about) manage a couple of Cisco ASAs (model 5510, version 8.4). None of us are Cisco experts.
We are attempting to increase our redundancy and during our discussions the following question came up.
Can an ASA 5510 be configured to inspect a packets destination IP address, detect if the target machine is up and re-direct to a different IP address if it isn't?
My understanding was that this was a server farm management software function rather than a router function but one of our team thought that perhaps the ASA can do it as it's more than just a router.
If so, would anyone be able to tell me the name of the protocol/technology so I can do some research and learn how it works?
I turn to Stack Exchange because my research so far has only uncovered articles about failover and alternative links between routers.
Any nudge in the correct general direction would be greatly appreciated.
Thank you for taking the time to read my question.
