Interzone network communications

Hi Experts,

I've read: https://blogs.oracle.com/stw/solaris-10-zones-and-networking-common-considerations  - which is related to Solaris 10, but I assume is practical for Solaris 11.3.

I have a global Solaris 11.3 (SRU: 11.3.35.6.0) T7-2 server that has two local zones.

Zone-A is an application zone.

Zone-B is an database zone.

Zone-A communicates to Zone-B for database things.

It appears that this communication commences at Zone-A, goes out to the switch and then comes back to Zone-B to get the data. And then the data goes out of Zone-B to the switch and back to Zone-A.

Note:
Zone-A needs to communicate with another App zone Zone-A1 (There is Zone-A2, Zone-A3, Zone-A#, as well).
