Deploying a Load-Balanced Edge Server Pool
To deploy a load balanced Edge Server Pool, follow these steps:
1. Select Multiple Computer Pool, and click Next.
2. If a single public
IP address will be used for the Access Edge, Web Conferencing Edge, and
A/V Edge services, check the box Use a Single FQDN and IP Address. This
requires using ports other than 443 for two of the services.
3. If federation will be used, check the Enable Federation box.
4. If XMPP federation will be used, check the Enable XMPP Federation box, and then click Next.
5. Check valid IP
options as they relate to your deployment. If your deployment is using
IPv6, check the IPv6 boxes for the internal and external interface. If
not, ensure that only the IPv4 boxes are checked.
6. If the IP address
used for the A/V Edge uses NAT, check the box The External IP Address
of This Edge Pool Is Translated by NAT. Click Next when complete.
7. Under the Access Edge Service section, enter the external FQDN and port. Typically, this is similar to sip.companyabc.com and port 443.
Note
If you elected to use a single FQDN and IP
address for your public edge services, you will be permitted to enter
only a single FQDN, and the default ports will be set to 5061, 444, and
443.
8. Under the Web
Conferencing Edge Service section, enter the external server FQDN and
port. Typically, the name and port are similar to webconf.companyabc.com and port 443.
9. Under the A/V Edge Service section, enter the external server FQDN and port. Typically, the name and port are similar to av.companyabc.com and port 443. Click Next when complete.
10. Define each server in the Edge Server Pool. Click Add.
11. Enter the internal IP Address of the Edge Server and the Internal Server FQDN, and click Next.
Note
Each member of the Edge Server pool must have
a unique external IP address for each public service, as well as a
unique internal IP address. Your load-balancing method will distribute
traffic to each member on the designated IP addresses. In the wizard,
make sure you are entering the IP addresses assigned to the pool
member, not that of the pool.
12. Under the Access Edge Service section, enter the external IP address assigned to the Edge Server.
13. Under the Web Conferencing Edge Service section, enter the external IP address assigned to the Edge Server.
14. Under the A/V Edge Service section, enter the external IP address assigned to the Edge Server, and click Finish.
15. Repeat the previous steps for each pool member and then click Next.
16. Select a next-hop
pool to be used by the Edge Server pool and click Next. If a director
is deployed, you should select the director as the next-hop.
17. Select
any Front End Server pools or Mediation Server pools that will use this
Edge Server pool for external media traffic. Click Finish to complete
the wizard.
Publish the Topology
After the topology is modified to include the
Edge Server pool, the configuration can be published. This step
publishes the changes to the Central Management Store, and all existing
Lync Server servers will update their local configuration stores to
match.
1. Ensure that the Lync Server Topology Builder is open and contains the Edge Server pool that was recently added.
2. Click the top node of the Topology Builder, Lync Server 2013.
3. Click the Action
menu and select Publish Topology, or select Publish Topology from the
Actions pane on the right side of the console.
4. Click Next to begin publishing the topology.
5. When the log indicates a successful update, click Finish to complete the wizard.
