What is the difference between Performance Routing and Cisco IOS Optimized Edge Routing (OER)?
A. Cisco Performance Routing takes advantage of the vast intelligence embedded in Cisco IOS Software to determine the optimal path based upon network and application policies. Cisco Performance Routing is an evolution of the Cisco IOS OER technology with a much broader scope. OER was originally designed to provide route control on a per destination prefix basis, but Performance Routing has expanded capabilities that facilitate intelligent route control on a per application basis. The expanded capabilities provide additional flexibility and more granular application optimization than OER.
Optimized Edge Routing was first introduced in Cisco IOS Releases 12.3(8)T, and 12.2(33)SRB. Performance Routing is an extension of OER. The leading keyword PfR syntax was introduced in Cisco IOS Release 15.1(2)T.
