Abstract

In this post we'll see how to connect an Edge Router to a physical LAN.

Introduction

In the previous post an Edge router has been deployed and configured with OSPF.

Configuring the Edge router

Now the edge router must be connected to external networks:

NSX OSPF Topology

An uplink interface needs to be bound to a PortGroup not configured for NSX. In other words a PortGroup named 172.31.30./27 has been manually added to the same Distributed vSwitch used for NSX:

Standard PortGroup

Now go to Networking & Security -> NSX Edges, double click on the edge and go to Manage -> Settings -> Interfaces. Select an available interface and configure it as Uplink, bound to the distributed PortGroup created above:

Edit NSX Edge Interface

Go now to Routing -> Global Configuration and press the Edit button to set the default gateway:

Edit NSX Edge default gateway

Now the edge router can reach the external network 172.31.30.0/27 and will use the 172.31.30.2 as a default gateway. The default gateway will now be redistributed via OSPF.

See the next post for configuring firewall and bidirectional NAT.
