11.3. Extended Community Flow Specification Actions (扩展社区流规范操作)
本文档中定义的 Extended Community Flow Specification Action 类型由两部分组成:
- Type (BGP Transitive Extended Community Type)
- Sub-Type
对于类型部分, IANA 维护一个名为 "BGP Transitive Extended Community Types" 的注册表。为了本工作的目的 (Section 7), IANA 已更新参考, 如下表所示。(注意: 本文档废弃了 [RFC7674] 和 [RFC5575], 对这些文档的所有引用已在注册表中删除。)
| 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
对于 Extended Community Traffic Filtering Actions 的子类型部分, IANA 维护以下注册表。IANA 已根据下表更新所有名称和参考, 并为 "Flow spec traffic-rate-packets" Sub-Type 分配一个新值。(注意: 本文档废弃了 [RFC7674] 和 [RFC5575], 对这些文档的所有引用已从下面的注册表中删除。)
| 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
此外, IANA 已将注册表 "Generic Transitive Experimental Use Extended Community Part 2 Sub-Types" 和 "Generic Transitive Experimental Use Extended Community Part 3 Sub-Types" 的参考更新为 RFC 8955。
本文档中定义的 "traffic-action" Extended Community (Section 7.3) 有 46 个未使用的位, 可用于传达附加含义。IANA 创建并维护一个名为 "Traffic Action Fields" 的注册表。IANA 已将此注册表的参考更新为 RFC 8955。此外, IANA 已根据下表更新参考。这些值应仅通过 IETF Review 规则分配。(注意: 本文档废弃了 [RFC7674] 和 [RFC5575], 对这些文档的所有引用已从注册表中删除。)
| Bit | Name | Reference |
|---|---|---|
| 47 | Terminal Action | RFC 8955 |
| 46 | Sample | RFC 8955 |
