In this encapsulation, the source UDP port can be used as an entropy field for purposes of load balancing, while the protocol of the encapsulated packet in the GRE payload is identified by the GRE Protocol Type. This document specifies requirements for two applicability scenarios for this encapsulation: (1) General Internet and (2) well-managed operator networks; less restrictive requirements apply to the latter scenario by comparison to the former.}, }
