What is a Distributed Logical Router (DLR) ?

A Distributed Logical Router (or Logical Distributed Router) is typically used to route East/West traffic between Logical Switches.

In this example, we will create a new DLR with two Internal interfaces to connect the App_Tier and Data_Tier Logical Switches. FInally we’ll add an Uplink interface to connect the DLR to a “transit” logical switch.
