GTM/LTM persistence error.
Hi all, this is my first post here, been following the forum for a good while now.
As so, the first question already seems to be a tricky one (I searched for this but failed to find anything).
I have a 3dns pointing to 2 bigip instances. The 3dns has source address persistance. Bigip uses cookie persistance.
The 2 bigip instances are geographically separated. behind every bigip instance, I have a few servers.
The problem is, users are being redirected from one bigip instance to the other, even withing the allowed ttl (1800 seconds).
Either because they can "get out" through different proxies (external IPs will be different - just an assumption) or for some other reason, not entirely sure. I noticed the cookie is set to session too, without expiration date and even so, we end up with cookies for both bigip instances.
Can someone please provide some advice or just point me to where I should be searching for the answer?
I'm still learning this, so any help is appreciated.
Thanks a lot in advance!
