Symptoms:
- Creating or Editing a Segment fails with the error
"IP address A.B.C.D/X overlaps with LbVirtualServer <> that has IP address A.B.C.D."
- The segment and the LB Virtual Server are configured on separate Tier 1 Gateways
- The LB VIP is an IP in the range of the Segment IP subnet
- Note: if the Segment and Virtual Server are configured on the same Tier 1 Gateway, this error is expected.
- On the NSX manager "get log-file policy.log" may have a log entry like this example
