The Performance Routing - Link Groups feature introduces the ability to define a group of exit links as 
a preferred set of links, or a fallback set of links for Optimized Edge Routing (OER) to use when 
optimizing a specified traffic class. Primary and fallback link groups can be configured at the master 
controller. Link groups provide a method of grouping links such as high bandwidth links to be used, for 
example, by video traffic, by configuring an OER policy that specifies the best link is to be selected from 
the link group that consists of only high bandwidth links.

Configuration information is included in the “Configuring and Applying OER Policies” chapter of the
