OSPFv3 Instance ID Registry Update
OSPFv3实例ID注册表更新
Abstract
摘要
This document modifies the "Unassigned" number space in the IANA "OSPFv3 Instance ID Address Family Values" registry by dividing it in two halves -- one half Unassigned but managed via Standards Action, and the other Reserved for Private Use. It updates RFC 5838.
本文档通过将IANA“OSPFv3实例ID地址系列值”注册表中的“未分配”数字空间分成两半进行修改——一半未分配，但通过标准操作进行管理，另一半保留供私人使用。它更新了RFC5838。

[RFC5838] defined the "OSPFv3 Instance ID Address Family Values" registry for the purpose of mapping OSPFv3 Instance IDs to different address families. The following table lists the value ranges that were allocated for [RFC5838] and Unassigned.
[RFC5838]定义了“OSPFv3实例ID地址系列值”注册表，以便将OSPFv3实例ID映射到不同的地址系列。下表列出了分配给[RFC5838]和未分配的值范围。

In some networks, additional OSPFv3 instances may be required to operationally identify specific applications. This need requires a pool of Instance IDs that the operator may locally assign for that purpose.
在某些网络中，可能需要额外的OSPFv3实例来在操作上识别特定应用。这需要一个实例ID池，操作员可以为此在本地分配。
For example, [OSPF-EMBED] describes an application in which IPv4- embedded IPv6 addresses [RFC6052] are used to transport IPv4 packets over an IPv6 network. While the IPv4-embedded IPv6 addresses do in fact represent IPv6 destinations, it would be operationally beneficial to be able to easily identify the specific application by having a separate space to do so. This benefit is enabled by the allocation of a range of Private Use Instance IDs.
例如，[OSPF-EMBED]描述了一个应用程序，其中IPv4嵌入IPv6地址[RFC6052]用于通过IPv6网络传输IPv4数据包。虽然IPv4嵌入式IPv6地址实际上代表IPv6目的地，但如果能够通过单独的空间轻松识别特定的应用程序，这在操作上是有益的。这一好处是通过分配一系列专用实例ID实现的。
This document modifies the IANA "OSPFv3 Instance ID Address Family Values" registry by designating a range as Reserved for Private Use. For the remaining unassigned values, the registration procedure is Standards Action.
本文档修改IANA“OSPFv3实例ID地址系列值”注册表，将范围指定为专用范围。对于其余未分配的值，注册过程为标准操作。
The IANA "OSPFv3 Instance ID Address Family Values" registry has been updated so that Instance IDs from 192-255 are Reserved for Private Use [RFC5226]. For the remaining unassigned values (128-191), the registration procedure is Standards Action. The registry now shows:
IANA“OSPFv3实例ID地址系列值”注册表已更新，因此192-255的实例ID保留供私人使用[RFC5226]。对于剩余的未分配值（128-191），注册过程为标准操作。注册表现在显示：
+--------------------------+---------------+-----------------------+
| Value | Description | Reference |
+--------------------------+---------------+-----------------------+
| 128-191 | Unassigned | 192-255 |
| Reserved for Private Use | this document | Private Use [RFC5226] |
+--------------------------+---------------+-----------------------+
+--------------------------+---------------+-----------------------+
| Value | Description | Reference |
+--------------------------+---------------+-----------------------+
| 128-191 | Unassigned | 192-255 |
| Reserved for Private Use | this document | Private Use [RFC5226] |
+--------------------------+---------------+-----------------------+
This document requests the modification of the "OSPFv3 Instance ID Address Family Values" registry as described in Section 2. The reference to [RFC5838] has been removed from the registry for the modified ranges.
本文件要求修改第2节所述的“OSPFv3实例ID地址系列值”注册表。已从修改范围的注册表中删除对[RFC5838]的引用。
This document modifies an IANA registry defined in [RFC5838]. It does not introduce any new security issues.
本文件修改了[RFC5838]中定义的IANA注册表。它不会带来任何新的安全问题。
