A bridge cluster is a collection of transport nodes that do bridging and participate in high availability (HA). Only one transport node is active at a time. Having a multi-node cluster of NSX-T bridge nodes helps ensure that at least one NSX-T bridge node is always available. To create a bridge-backed logical switch, you must associate it with a bridge cluster. Therefore, even if you have only one bridge node, it must belong to a bridge cluster to be useful.

About this task

After creating the bridge cluster, you can later edit it to add additional bridge nodes.


  • Create at least one NSX-T 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. In the NSX Manager UI, navigate to Fabric > Configuration > Bridges.
  2. Give the bridge cluster a name.
  3. Select a transport zone for the bridge cluster.

    The transport zone must be of type overlay, not VLAN.

  4. From the Available column, select transport nodes and click the right arrow to move them to the Selected column.

What to do next

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