This document defines an extension to the Service Function Chain (SFC) Operation, Administration and Maintenance (OAM) that enables control of the Echo Reply return path directing it over a Reverse Service Function Path. Enforcing the specific return path can be used to verify the bidirectional connectivity of SFC and increase the robustness of SFC OAM.
