CLIThis section covers the configuration steps for topology policy to select the GSLB Service pool using
NSX Advanced Load Balancer
CLI.To configure the topology policy to select the GSLB service pool:
- Enable topology policy at GSLB Service level by setting the topology_policy_enabled knob to True.[admin:ctrl]: > configure gslbservice GS-1 Updating an existing object.
