Comment 1 for bug 1655204

Section of network-environment.yaml in question:

  # Uncomment if using the Management Network (see network-management.yaml)
  # ManagementNetCidr: 10.0.1.0/24
  # ManagementAllocationPools: [{'start': '10.0.1.10', 'end', '10.0.1.50'}]
  # Use either this parameter or ControlPlaneDefaultRoute in the NIC templates
  # ManagementInterfaceDefaultRoute: 10.0.1.1
  # Define the DNS servers (maximum 2) for the overcloud nodes

# ManagementAllocationPools: [{'start': '10.0.1.10', 'end', '10.0.1.50'}]

Should be:

# ManagementAllocationPools: [{'start': '10.0.1.10', 'end': '10.0.1.50'}]
