Create Edge Cluster

Warning: VMware Enterprise PKS v1.6 is no longer supported because it has reached the End of General Support (EOGS) phase as defined by the Support Lifecycle Policy. To stay up to date with the latest software and security updates, upgrade to a supported version.

This topic provides instructions for creating an NSX-T Edge Cluster for use with VMware Enterprise PKS.

Prerequisites

Make sure you have completed all preceding NSX-T installation tasks.

About Edge Clusters

In NSX-T Data Center, an Edge Cluster is a logical boundary for resourcing. Having a multi-node cluster of NSX-T Edge Nodes helps ensure that at least one NSX Edge is always available. To create a Tier-0 logical router or a Tier-1 router with stateful services such as NAT, a traffic load balancer, and other virtual network objects, you must associate them with an NSX Edge cluster.

An Edge Cluster can have a maximum of 10 Edge Nodes. If the provisioning requires more Edge Nodes than what a single Edge Cluster can support, multiple Edge Clusters must be deployed. An NSX-T Edge Transport Node can be added to only one NSX-T Edge cluster. After creating the NSX-T Edge cluster, you can later edit it to add additional NSX-T Edge Nodes. An NSX-T Edge cluster can be used to back multiple logical routers.

For more information, see Edge Clusters in the NSX-T Data Center documentation.

Create Edge Cluster

Create an NSX Edge Cluster and add each Edge Transport Node to the Edge Cluster by completing the following procedure:

  1. In NSX Manager, select System > Fabric > Nodes > Edge Clusters.

  2. Click Add.

  3. Configure the NSX Edge Cluster as follows:

    • Name: For example, edgecluster1.
    • Edge Cluster Profile: Select nsx-default-edge-high-availability-profile from the menu.
    • Transport Nodes > Member Type: Select Edge Node from the menu.
    • From the Available column, select both NSX-T Edge Nodes and click the right-arrow to move them to the Selected column.
    • Click Add.

Verify Edge Cluster Creation

To verify Edge Cluster creation, complete the following steps:

  1. In NSX-T Manager, select System > Fabric > Nodes > Edge Clusters.

  2. Verify that you see the new Edge Cluster.

  3. Select Edge Cluster > Related > Transport Nodes.

  4. Verify that both Edge Transport Nodes are members of the Edge Cluster.

  5. SSH to NSX Edge Node 1 and run the following commands to verify proper connectivity.

    nsx-edge-1> get vteps
    nsx-edge-1> get host-switches
    nsx-edge-1> get edge-cluster status
    nsx-edge-1> get controller sessions
    
  6. SSH to NSX Edge Node 2 and repeat the above commands to verify proper connectivity.

  7. Get the TEP IP addresses.

    • Navigate to System > Fabric > Nodes > Edge Transport Nodes.
    • Select the Edge Transport Node, such as nsx-edge-1-tn.
    • Select the Monitor tab.
  8. Verify Edge-TN1 to Edge-TN2 connectivity (TEP to TEP).

    nsx-edge-1> get logical-router
    nsx-edge-1> vrf 0
    nsx-edge-1(vrf)> ping TEP-IP-ADDRESS-EDGE-2
    

You should be able to ping Edge Transport Node 2 using the TEP address.

Next Step

Prepare ESXi Hosts in the Compute Cluster as Transport Nodes.
