When creating an Network Load Balancer (NLB) instance, you do not need to specify all zones forwarding. After the instance is created, the all zones forwarding feature is enabled by default, and you can modify it as needed.

Action description

After disabling all zones forwarding, the NLB instance can only forward access requests to backend servers within the same Availability Zone. For example, access requests from Availability Zone A can only be forwarded to backend servers in Availability Zone A for processing. For detailed information about all zones forwarding, see all zones forwarding.

Procedures

In the top menu bar, select the target project and region.

Click the target NLB instance name.

In the instance attribute zone, enable/disable the all zones forwarding feature.

Click OK to complete the action.
