Who Me Too'd this topic

I'm wondering where I can find official documentation about process of Internal Gateway Selection. There is only a broad documentation how does the external process looks like. Right now I'm testing a setup to have a redundant Internal Gateways to avoid single point of failure, and what I can see in my observation is that GP is connecting to every Internal Gateway on the list.

Further more depending on a dice roll I think, user-id to ip mapping is created on some of them. I saw already few situation:

- mapping created only on one gateway further away in terms of latency, redistributed to others

- mapping created on two gateways, one with low latency, one with high, redistributed to others

- mapping created on all four gateways

I'm just wondering how it was designed by Palo Alto, and if that's an expected result.
