Create your Edge topology for Skype for Business Server 2015

Summary: Learn how to build, publish, and export your Edge Server topology in Skype for Business Server 2015.

Topology Builder is the tool you need to use to build your Edge Server topology, just as it's used for any topology component for Skype for Business Server 2015. Before following the steps below, you will need to have set up at least one Front End pool or a Standard Edition server.

We cover the following topics in this article:

  • Build your Edge Server topology

  • Publish your Edge Server topology

  • Export your Edge Server topology

    Note

    To follow the steps below, you're going to need to log into the domain servers mentioned below as a user who's a member of the following domain groups:

  • RTCUniversalServerAdmins

  • Domain Admins

Build your Edge Server topology

The first deployment step is building your Skype for Business Server 2015 Edge Server topology, which consists of one of three options:

  • A single Edge Server

  • A DNS load balanced Edge pool (one or more servers)

  • A hardware load balanced Edge pool (one or more servers)

If you aren't sure what you need, then before you start following these steps, it's a good time to go over the Planning documentation. Otherwise, let's begin.

Defining the topology for a single Edge Server

  1. Log onto your Skype for Business Server 2015 Standard Edition server, or a Skype for Business Server 2015 Front End pool.

  2. Once there, open Skype for Business Server 2015 Topology Builder.

  3. In the console tree, expand the site you're going to deploy the Edge Server to.

  4. Right-click Edge pools, and then click New Edge pool.

  5. You'll click Next on the Define New Edge pool screen.

  6. On the Define the Edge pool FQDN screen, type the internal fully qualified domain name (FQDN) that the Edge Server is going to use, and select Single computer pool, clicking Next when done.

  7. On the Select features screen, you have a choice:

    • You may intend to use the same FQDN and IP address for your SIP Access service, your Skype for Business Server 2015 Web Conferencing service, and your A/V Edge service. If so, you need to choose the Use a single FQDN and IP address checkbox (and keep this in mind for Step 9 below)

    • If you're planning to enable federation, choose the Enable federation for this Edge pool (Port 5061) check box.

  8. Once you've clicked Next, you'll find yourself on the IP Options screen. Your options are as follows:

    • Enable IPv4 on the internal interface

    • Enable IPv6 on the internal interface

    • Enable IPv4 on the external interface

    • Enable IPv6 on the external interface

    These are pretty self-explanatory, whether you're using IPv4 or IPv6 addresses, and you're applying those addresses on your Edge Server internally or externally (you'll need to keep this in mind for Step 10). You also have the option of configuring your Edge Server or your Edge pool to use a network address translation (NAT) address for the external IP address. You can do this by choosing The external IP address of this Edge pool is translated by NAT check box . Click Next when ready.

  9. On the External FQDNs screen, your choices depend on the selection you made in Step 7 above.

    • If you checked the Use a single FQDN and IP Address check box, you need to enter your single external FQDN in the SIP Access box. Then you'll need to enter different port numbers for each edge service to allow them all to connect independently. We recommend 5061 for the SIP Access Edge service, 444 for the Web Conferencing Edge service, and 443 for the A/V Edge service. Click Next when done.

    • If you didn't check the Use a single FQDN and IP Address check box, you'll now need to enter the three external FQDNs for the SIP Access Edge service, the Web Conferencing Edge service, and the A/V Edge service. Click Next when done.

  10. You're now on the Define the Internal IP address screen. Here you'll type the IP address of your Edge Server in the Internal IPv4 address and Internal IPv6 address text boxes, depending on the choices you made back in Step 8. Click Next when ready.

  11. On the Define the External IP address screen, you have a few options depending on your previous choices:

    • You may be using a single FQDN for all services. If so, type your external IPv4 or IPv6 address (whichever you're using) into the SIP Access text box, and then click Next.

    • You may have chosen to use three separate FQDNs and IP addresses for the services. If that's the case, enter your external IPv4 or IPv6 addresses for the SIP Access Edge service, the Web Conferencing Edge service, and the A/V Edge service, and then click Next.

    Note

    If you didn't previously choose to enable and assign IPv6 addressing, you won't see this dialog box. That's normal, just go to the next step.

  12. If you chose to use NAT back in Step 8, you'll now get a screen with a Public IP address textbox. You'll need to enter the public IPv4 and/or IPv6 address you've set for the A/V Edge service, to be translated by NAT. Then click Next.

  13. Next screen up is Define the next hop. In the Next hop pool box, select the name of your internal pool, which might be a Front End pool or a Standalone pool. If you have a Director in your environment, you should choose the Director. Then click Next.

  14. On the Associate Front End pools screen, you'll need to specify one or more internal pools, including Front End pools and Standard Edition servers, to associate with this Edge Server. Just choose the names of the internal pools you want using this Edge Server to communicate with supported external users. Click Next.

    Note

    Something to keep in mind here is, if your internal pools or standalone servers are already using a different Skype for Business Server 2015 Edge Server, they can't have multiple associations. If you choose an internal pool or standalone server that's in that situation, you'll see a warning appear telling you about the other Edge Server, and you can decide whether you want to continue or not. If you go ahead with this new association, the connection to the other Edge Server will stop.

  15. Click Finish on the next screen.

  16. Now you'll be able to publish this updated technology, and follow the instructions in Deploy Edge Servers in Skype for Business Server 2015 to deploy to your Edge Server from here.

    Note

    If you didn't previously choose to enable and assign IPv6 addressing, you won't see this dialog box. That's normal, just go to the next step.

  13. Click Finish. The Edge Server you just created should now be listed in the Define the computers in this pool dialog box.

  14. While still on the Define the computers in this pool screen, click the Add button again and repeat steps 11 through 13 until you've added all the Edge Servers you intend to have in this pool. When this is complete, click Next.

  15. If you chose to use NAT back in Step 8, you'll now get a screen with a Public IP address textbox. You'll need to enter the public IPv4 and/or IPv6 address you've set for the A/V Edge service, to be translated by NAT. Then click Next.

Publish your Edge Server topology

Once you've finished the steps above, it's time to publish this new topology, which will also allow you to export it to your Skype for Business Server 2015 Edge Server or Edge pool. Follow these steps:

  1. Start Topology Builder (if it's not started already from the previous procedure).

  2. In Topology Builder, in the console tree, right-click Skype for Business Server 2015 and then click Skype for Business Server Topology Builder.

  3. On the Welcome page of the wizard, click Next.

  4. On the Create other databases page, click Next.

  5. When the status indicates that the database creation succeeded, do the following:

    • To view the log, click View log.

    • To close the wizard, click Finish.

Export your Edge Server topology

To deploy successfully, the Skype for Business Server 2015 Deployment Wizard needs access to the Central Management store data. For internal servers in your domain or forest, this typically is straightforward. Edge Servers are outside of the domain, and so it's necessary to manually export the topology file to the Edge Server location, usually on a physical media. This export is done via PowerShell:

  1. Start the Skype for Business Server Management Shell.

  2. In the Skype for Business Server Management Shell, run the following:

    Export-CsConfiguration -FileName <ConfigurationFilePath.zip>
    
  3. Copy the exported file to external media (for example, a USB drive or network share that you can reach from the Edge Server's location).
