11. IANA Considerations​

This section complies with [RFC7153].

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.)

134L3VPN Dissemination of Flow Specification rulesRFC 8955

Table 9: Registry: SAFI Values

11.2. Flow Component Definitions​

A Flow Specification consists of a sequence of flow components, which are identified by an 8-bit component type. IANA has created and maintains a registry entitled "Flow Spec Component Types". IANA has updated the reference for this registry to RFC 8955.

11.3. Extended Community Flow Specification Actions​

The Extended Community Flow Specification Action types defined in this document consist of two parts: Type (BGP Transitive Extended Community Type) and Sub-Type.

For the type part, IANA maintains a registry entitled "BGP Transitive Extended Community Types". For the purpose of this work (Section 7), IANA has updated the references as shown in the table below.
