Network region links in Lync Server represent a bandwidth constraint between two network regions or central sites. Because network regions are generally geographically large, these links apply to a number of sites when communicating across regions. For example, a region link might be defined between North America and Europe for an organization. Region links are created between only two regions and can have a bandwidth policy profile associated. The bandwidth policy can be an existing policy or an administrator can create a new policy specifically for the region link.
To create a new network region link, follow these steps:
1. Open the Lync Server 2013 Control Panel.
2. Click Network Configuration.
3. Click Region Link.
