NimbostratusSend traffic to second wide ip if the first wide ip fails
Hello all. My question is this: I have two wide IPs on my GTM. VCC.test1.com and VCC.test2.com. What we want to be able to do is have all traffic go to VCC.test1.com. However, if any part of VCC.test...

CirrostratusGTM is about resolving domain names to IP addresses, so on it's own I don't think you can do what you are saying. However, what might meet your requirement is to configure a fallback IP in your GTM pool with the address of an LTM virtual which issues a redirect to vcc.test2.com
- Robert_Roman_14So if I am understanding you correctly, I could add a fallback ip on the VCC.test1.com pool that points to the virtual server of vcc.test2.com so that if all of the virtual servers that point to vcc.test1.com in the pool are unaccessible, it will be picked up by default an thus route to vcc.test2.com?
- uni_87886That's not what I meant, but if you only want to resolve to the addresses of test2, but don't care that they receive requests with the test2 host header, then the better way to do it is to have a pool of test1 servers and a pool of test2 servers. Configure the wideip with global availability with the preference to the test1 pool.
- Robert_Roman_14What they want is to have everyone go to vcc.test1.com. If at any point that is unreachable, they want people to automatically be routed to vcc.test2.com and like you said, it doesnt sound possible to accomplish on the wide ip level. I dont think that the fallback ip scenario is something that they will want to do, but it is an option at least. Thanks for the information!
