11.3. Extended Community Flow Specification Actions
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)
- 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. (Note: This document obsoletes both [RFC7674] and [RFC5575], and all references to those documents have been deleted in the registry.)
| Type Value | Name | Reference |
|---|---|---|
| 0x81 | Generic Transitive Experimental Use Extended Community Part 2 (Sub-Types are defined in the "Generic Transitive Experimental Use Extended Community Part 2 Sub-Types" Registry) | RFC 8955 |
| 0x82 | Generic Transitive Experimental Use Extended Community Part 3 (Sub-Types are defined in the "Generic Transitive Experimental Use Extended Community Part 3 Sub-Types" Registry) | RFC 8955 |
Table 12: Registry: BGP Transitive Extended Community Types
For the sub-type part of the Extended Community Traffic Filtering Actions, IANA maintains the following registries. IANA has updated all names and references according to the tables below and assign a new value for the "Flow spec traffic-rate-packets" Sub-Type. (Note: This document obsoletes both [RFC7674] and [RFC5575], and all references to those documents have been deleted from the registries below.)
| Sub-Type Value | Name | Reference |
|---|---|---|
| 0x06 | Flow spec traffic-rate-bytes | RFC 8955 |
| 0x0c | Flow spec traffic-rate-packets | RFC 8955 |
| 0x07 | Flow spec traffic-action (Use of the "Value" field is defined in the "Traffic Action Fields" registry) | RFC 8955 |
| 0x08 | Flow spec rt-redirect AS-2octet format | RFC 8955 |
| 0x09 | Flow spec traffic-remarking | RFC 8955 |
Table 13: Registry: Generic Transitive Experimental Use Extended Community Sub-Types
| Sub-Type Value | Name | Reference |
|---|---|---|
| 0x08 | Flow spec rt-redirect IPv4 format | RFC 8955 |
Table 14: Registry: Generic Transitive Experimental Use Extended Community Part 2 Sub-Types
| Sub-Type Value | Name | Reference |
|---|---|---|
| 0x08 | Flow spec rt-redirect AS-4octet format | RFC 8955 |
Table 15: Registry: Generic Transitive Experimental Use Extended Community Part 3 Sub-Types
Furthermore, IANA has updated the reference for the registries "Generic Transitive Experimental Use Extended Community Part 2 Sub-Types" and "Generic Transitive Experimental Use Extended Community Part 3 Sub-Types" to RFC 8955.
The "traffic-action" Extended Community (Section 7.3) defined in this document has 46 unused bits, which can be used to convey additional meaning. IANA created and maintains a registry entitled "Traffic Action Fields". IANA has updated the reference for this registry to RFC 8955. Furthermore, IANA has updated the references according to the table below. These values should be assigned via IETF Review rules only. (Note: This document obsoletes both [RFC7674] and [RFC5575], and all references to those documents have been deleted from the registry.)
| Bit | Name | Reference |
|---|---|---|
| 47 | Terminal Action | RFC 8955 |
| 46 | Sample | RFC 8955 |
