F5 Disign for Gobal single IP
Hi all, I am designing solution for our internal application using F5. I am very new to F5 so just started learning about basic F5 concepts. I have a little complicated question related to F5 Design, please help to clarify
Idea of using F5 not for load sharing it’s for single IP, since traffic already shared at Network level (NE1 & NE2 will have equal amount of traffic) let me explain the call flow so that you can understand the F5 need here. UE (user traffic) will send only to single IP say 10.200.10.100 (BIGIP) , so that traffic will arrive at NE1 and NE2 (RR mode). Router 1 should send the traffic F5(1) 1st available path . Router 2 should send the traffic to F5 (2) 1st available path. i.e Region X F5 (1) configured with BIG IP 10.200.10.100 which is advised in Router 1 as 1st available path. Region Y F5 (2) configured with BIG IP 10.200.10.100 which is advised in Router2 as 1st available path . UE invoke 10.200.10.100 -> NE 1 -> Router 1 -> Switch 1 -> F5 (1) -> App 1 UE invoke 10.200.10.100 -> NE 2 -> Router 2 -> Switch 2 -> F5 (2) -> App 2 In case if F5 (1) is down then Router 1 will take secondary route available via router 2 to reach the application. (vice versa) i.e UE invoke 10.200.10.100 -> NE 1 -> Router 1 -> Router 2 -> Switch 2 -> F5 (2) -> App 2.
Is this design correct ? can F5 work in this mode ? as I know some part of job is done by router. Just want to check if any limitation at F5 side.
