A bridge cluster is a collection of ESXi host transport nodes that can provide layer 2 bridging to a logical switch.

A bridge cluster can have a maximum of two ESXi host transport nodes as bridge nodes. With two bridge nodes, a bridge cluster will provide high availability in an active-standby mode. Even if you want to have one bridge node, you still must create a bridge cluster. After creating the bridge cluster, you can add an additional bridge node later.


  • Create at least one NSX-T Data Center transport node for use as a bridge node.
  • The transport node used as a bridge node must be an ESXi host. KVM is not supported for bridge nodes.
  • It is recommended that bridge nodes not have any hosted VMs.
  • A transport node can be added to only one bridge cluster. You cannot add the same transport node to multiple bridge clusters.


  1. Select Fabric > Nodes from the navigation panel.
  2. Click the ESXi Bridge Clusters tab.
  3. Click Add.
  4. Enter a name and optionally a description.
  5. Select a transport zone for the bridge cluster.
  6. From the Available column, select transport nodes and click the right arrow to move them to the Selected column.
  7. Click the Add button.

What to do next

You can now associate a logical switch with the bridge cluster.
