Dear Authors, In section 3.3.2.1 (LAG/ECMP), the change suggested below articulates the inference of entropy in a much better way.
>>The entropy information MAY be inferred from the NVO3 overlay header or >>underlay header. The entropy information should be ideally present in the overlay header e.g. Entropy Label for MPLS [RFC 6790], VXLAN - UDP source port. In case the overlay protocol does not support the necessary entropy information or the switches/routers in the underlay do not support parsing of the additional entropy information in the overlay header, the following support is needed in the underlay switches/routers. The underlay switches and routers should be programmable, i.e. select the appropriate fields in the underlay header for hash calculation based on the type of overlay header - the point to note is even the location of the underlay header in the packet will vary based on the type of overlay header. Thanks, Ramki
