Configuring an A/S Tier-0 with a Tier-1 and 3-tier app topology with NSX-T Terraform Provider

This blog post and demo shows how you can use the Terraform NSX-T Provider to quickly configure an Active-Standby Tier-0 with a Tier-1 and a typical 3-tier app topology.


NSX-T Transport Node Profiles

Transport Node Profiles are introduced to automatically configure vCenter Clusters for NSX-T. Additionally a Transport Node Profile maintains Transport Node Configuration at the Cluster level to ensure that when a vSphere Host is added or removed from the cluster it will be automatically be configured or unconfigured. Creating a Transport Node profile has a lot of similarities with the Host Migration from VSS/VDS to N-VDS workflow, which is documented in the Host Migration to N-VDS blog post.


NSX-T Manager Clustering

In NSX-T 2.4 the NSX-T Manager is a Converged Appliance where Policy, Management and Control Roles are available on each NSX-T Manager Node and creating a Cluster of three NSX-T Managers. The NSX-T Managers in the Cluster also share a Distributed Persistent Datastore where the Desired State is stored. This feature brings the benefit of availability of all management services across the cluster, improves the install and upgrade process and makes operations easier with less systems to monitor and maintain.


NSX BGP Filters

In NSX BGP filters work like access lists for route advertisements (prefixes). The NSX BGP filters are prefix lists which work very similarly to firewall access lists. A prefix list contains one or more ordered entries which are processed sequentially. For each prefix entry you can specify inbound or outbound filters to allow certain routes to be advertised to or from the Edge Services Gateway/Distributed Logical Router.
For example you to want to prevent a route for 10.0.0.0/24 from being advertised in BGP from the NSX Edge Services Gateway.


Testing MAC Learning in the NSX L2 Bridge

One of our customers is preparing to migrate Virtual Machines from VLAN to VXLAN with the NSX L2 Bridge and asked me how to test the L2 Bridge and get confirmation that it is actually configured correctly and operational. All commands in this blog post are from the NSX Troubleshooting Documentation.

We can test if a bridge is functional by issuing a command on the NSX Manager.
