Important:
If you are using a one-armed topology, the load balancer does not need to be in place before installing and testing the Edge Servers. You can skip this step and proceed to Walkthrough: Configuring New Edge Servers.

If you are using a two-armed load balancer topology, you need to enable routing between the perimeter and edge networks. There are three distinct load balancer usages, but only two require routing. Depending on the type of load balancer, you may be able to use a single piece of hardware for all three usages. For details, check your model.

• Edge External.Connect the load balancer to the perimeter external and edge external networks and configure the appropriate IP addresses. Then, enable routing between these two networks. Do not configure any VIPs at this stage.
  
  
• Edge Internal.Connect the Load Balancer to the perimeter internal and edge internal networks and configure the appropriate IP addresses. Then enable routing between these two networks. (Do not configure any VIPs at this stage.)
  
  

After you have confirmed routing, you can move forward with installing and testing each Edge Server and reverse proxy server.
