Static Routing and HA VIP Design – Edge Node on two VDS with four Physical NICs

This is the next post on a series of posts on NSX-T Edge Node design topologies.
In this blog post I will describe an Edge Node design topology hosting a Tier-0 Gateway with Static Routing with a HA VIP address configured.

With the Edge Node Virtual Appliances it is important to know on which vSphere Hosts the Edge Nodes are going to run, how many physical NICs are available and if the Edge Node is running on top of a VSS/VDS or N-VDS and how teaming is configured. In this design topology the Edge Nodes are running on hosts with two VDS with four Physical NICs.

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 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.
