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.


VMware NSX and BGP Design and Configuration

Introduction

In this blog post I would like to share how BGP is configured on VMware NSX to automatically update routing information with the physical network.

Design

Recently I was involved in a project where we used BGP to peer the NSX environment with the physical network. The design we did was challenging because of scale. The NSX environment we deployed meant for a multi-tenant Cloud platform scaled for several hundreds of tenants.
