After a brief summary of the results, each response is listed. This document contains responses from three implementers who completed the survey (Cumulus Networks, Cisco Systems and Exa Networks). The editor did not use external means to verify the accuracy of the information submitted by the respondents. The respondents are considered experts on the products they reported on.},
