10. Comparison with RFC 2858

This document makes the use of the next hop information consistent with the information carried in the NEXT_HOP BGP path attribute.

This document removes the definition of SAFI 3 and deprecates SAFI 3.

This document changes partitioning of the SAFI space. Specifically, in RFC 2858 SAFI values 128 through 240 were part of the "private use" range. This document specifies that of this range, allocations that are currently in use are to be recognized by IANA, and that unused values, namely 130, 131, 135 through 139, and 141 through 240, should be considered reserved.

This document renames the Number of SNPAs field to Reserved and removes the rest of the SNPA-related information from the MP_REACH_NLRI attribute.
