11.1. AFI/SAFI Definitions

11.1. AFI/SAFI Definitions​

IANA maintains a registry entitled "SAFI Values". For the purpose of this work, IANA has updated the following SAFIs as shown in the table below. (Note: This document obsoletes both [RFC7674] and [RFC5575], and all references to those documents have been deleted from the registry.)

ValueNameReference
133Dissemination of Flow Specification rulesRFC 8955
134L3VPN Dissemination of Flow Specification rulesRFC 8955

Table 9: Registry: SAFI Values

The above textual changes generalize the definition of the SAFIs rather than change its underlying meaning. Therefore, based on "The YANG 1.1 Data Modeling Language" [RFC7950], the above text means that the following YANG enums from "Common YANG Data Types for the Routing Area" [RFC8294] have had their names and descriptions at https://www.iana.org/assignments/iana-routing-types changed to:

   enum flow-spec-safi {
          value 133;
          description
            "Dissemination of Flow Specification rules SAFI.";
        }
   enum l3vpn-flow-spec-safi {
          value 134;
          description
            "L3VPN Dissemination of Flow Specification rules SAFI.";
        }

A new revision statement has been added to the module as follows:

   revision 2020-12-31 {
     description "Non-backwards-compatible change of SAFI names
                  (SAFI values 133, 134).";
     reference
       "RFC 8955: Dissemination of Flow Specification Rules.";
  }
