Issue/Introduction
On the NSX UI, clicking on Networking -> Segments shows a Segment configured for bridging with a Failed status
Realization Error: There already exists a BridgeEndpoint on same edgeNodes [TN UUIDs] with same vlan-transportzone PolicyTransportZone/<UUID> and vlanid <VLANID>
Traffic that traverse the Bridge datapath is not working
The Bridge configuration is not realised on the Edge node, admin cli "get bridge summary" shows no Bridge configuration is present.
Environment
VMware NSX 4.x VMware NSX-T 3.x
Cause
Configuring multiple Bridges on the same Edge Nodes, using the same VLAN ID and VLAN Transport Zone is not supported.
Resolution
A Bridge configuration involves 3 components i.e. Edge Nodes, VLAN Transport Zone and VLAN ID. All 3 cannot be identical in 2 or more separate bridge configurations, at least 1 of them must be different.
Validate the Bridging configuration as follows:
On the NSX UI navigate to Networking -> Segments -> Profiles -> Edge Bridge Profiles
Identify if multiple edge Bridge profiles are configured on the same Edges
On Networking -> Segments, select the segments where Bridge Profile is applied
Validate the Transport Zone and VLAN ID of each segment to identify duplicate configuration
