To prevent such configuration to be pushed and realized on the edge nodes, a validation workflow has been introduced from 3.2.2 onwards which will throw an error on that specific segment and the segment will be in 'Failed' state on the NSX-T Manager UI when such configuration are made to a segment.
Example error would be: 'There already exists a BridgeEndpoint on same edgeNodes [TransportNode/cd82cf10-9485-4aef-a46b-aef24ad18f09] with same vlan-transportzone PolicyTransportZone/f4a35306-d9fd-43e7-a729-748492aec0c2 and vlanId 3265'
This will prevent such configuration to be pushed and get realized on the edge nodes.
The is resolved in NSX-T 3.2.2 and 4.0.0 available at
VMware Downloads.
Workaround:
Create a bridge profile and move all segments (except those with duplicate VLANs) from the existing bridge profile to the new bridge profile.
