NimbostratusSticky Persistence across 3 VIPs different IPs and Ports
My clients want me to load balance with sticky three tiers of applications.
First would be the web-tier.
The webserver is set-up to with one IP address and two ports
First VIP1 -10.123.a.a
Pool
members (Does this have to be a wildcard VIP?)
10.b.b.b:80
10.b.b.b:90
The application will then push sticky to VIP2 - 10.123.c.c
Pool members
10.d.d.d:8080
10.d.d.d:8080
These will send sticky requests to the same 10.d.d.d IP addresses, different ports.
Pool members
10.d.d.d:5601
10.d.d.d:5601
The info will be sent sticky to VIP 3 - 10.123.e.e
Pool members
10.f.f.f:8080
10.f.f.f:8080
Can anyone lead me in the proper direction as to how to get this done?
I guess that I will have to write an iRule but I’m not sure. I watched Deb & Colin’s video on sticky persistence across VIPs but it seems their solution was helped by the fact that the second VIP used the same pool member IPs. Can check boxes be used for this solution? How many pools do I need on the 2 VIP?
The F5 that I would put this on, is currently already in production. Thanks

Hi EFFFIVE,
Thanks for detailing the virtual server and pool configurations. As the pool member IP and ports are almost all different across the three pools, I don't see any intuitive logic for persisting "client" requests. Can you clarify what logic you want to implement here?

EFFFIVE_26332Authentication. A session has to be kept alive across the three different tiers. In the past I have done active passive on something like this to avoid a messy irule.- EFFFIVE_26332As far as logic I can get our applications people speaking with F5 to see if we can streamline things more efficiently but right now I need two questions answered. Can we do this on the F5? How?
