IANA Registry for P-Multicast Service Interface (PMSI) Tunnel Type Code Points
P-多播服务接口（PMSI）隧道类型代码点的IANA注册表
Abstract
摘要
RFC 6514 created a space of Tunnel Type code points for a new BGP attribute called the "P-Multicast Service Interface Tunnel (PMSI Tunnel) attribute". However, the RFC did not create a corresponding IANA registry.
RFC6514为新的BGP属性创建了一个隧道类型代码点空间，称为“P-多播服务接口隧道（PMSI隧道）属性”。但是，RFC没有创建相应的IANA注册表。
There now is need to make further code point allocations from this name space. This document serves to update RFC 6514 in that it creates an IANA registry for that purpose.
现在需要从这个名称空间进一步分配代码点。本文档用于更新RFC 6514，因为它为此创建了IANA注册表。

In 'BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs' [RFC6514], an optional transitive BGP attribute called the "P-Multicast Service Interface Tunnel (PMSI Tunnel) attribute" is specified. This BGP attribute uses an octet field to specify the PMSI tunnel type. RFC 6514 allocates the values 0-7.
在“MPLS/BGP IP VPN中多播的BGP编码和过程”[RFC6514]中，指定了一个可选的可传递BGP属性，称为“P-多播服务接口隧道（PMSI隧道）属性”。此BGP属性使用八位字段指定PMSI隧道类型。RFC 6514分配值0-7。
There is now a need to make further code point allocations from this name space. In particular, "Inter-Area P2MP Segmented LSPs" [SEAMLESS-MCAST] needs to make such an allocation. However, the RFC did not create an IANA registry for these code points.
现在需要从这个名称空间进一步分配代码点。特别是，“区域间P2MP分段LSP”[无缝-MCAST]需要进行这样的分配。但是，RFC没有为这些代码点创建IANA注册表。
This document creates a new IANA registry called "P-Multicast Service Interface Tunnel (PMSI Tunnel) Tunnel Types" for these code points. The registry is created in the "Border Gateway Protocol (BGP) Parameters" registry.
本文档为这些代码点创建了一个新的IANA注册表，名为“P-Multicast服务接口隧道（PMSI隧道）隧道类型”。注册表在“边界网关协议（BGP）参数”注册表中创建。
Creating this registry is an update of RFC 6514 [RFC6514].
创建此注册表是对RFC 6514[RFC6514]的更新。
This document simply creates an IANA registry from a table in RFC 6514. Thus, there are no security concerns.
本文档仅从RFC6514中的表创建IANA注册表。因此，不存在安全问题。
IANA has created a new registry called "P-Multicast Service Interface Tunnel (PMSI Tunnel) Tunnel Types" in the "Border Gateway Protocol (BGP) Parameters" registry.
IANA在“边界网关协议（BGP）参数”注册表中创建了一个名为“P-多播服务接口隧道（PMSI隧道）隧道类型”的新注册表。
The allocation policy for values 0x00 to 0xFA is IETF Review [RFC5226]. Values 0xFB to 0xFE are experimental and are not to be assigned. 0xFF is reserved, the status of 0xFF may only be changed through Standards Action [RFC5226].
值0x00到0xFA的分配策略是IETF评审[RFC5226]。0xFB到0xFE的值为实验值，不进行分配。0xFF是保留的，只能通过标准操作[RFC5226]更改0xFF的状态。
The initial registry should appear as:
