Error: aliasip: is already being used by another

Do you already have an issue opened with F5 support?

Not yet, it's not critical as I just tested the script for first time.

Description

When run gcloud deploy, i got error on aliasip as follows: When providing one value, the script errors on that one value. If providing two values (semicolon separator), got error on the second value. Result: only bigip1 is created.

ERROR: (gcloud.deployment-manager.deployments.create) Error in Operation [operation-1678698586130-5f6c478e948f3-93704f76-5de7a834]: errors:

Copied the aliasip in yaml file as below. My subnet1 is 10.0.2.0/24.

Same error if attempt to edit the big-ip instance and add alias IP range (smaller subnet) which is in same subnet1 as below screenshot.

Think I know the problem, when assigned 10.0.2.240/29, working fine. I forgot that google reserved .254 address .
