快速分段 LSP 配置
使用快速分段建立端到端分段路由路径
了解快速分段在多域网络中建立端到端分段路由路径的优势、用例和概述。
快速航段的好处
-
快速分段是底层路径的分段路由 （SR） 抽象。快速网段有助于使用任何底层技术建立端到端 SR 路径。 目前支持的底层技术是 RSVP-TE 和 SR-TE。下面介绍了通过 RSVP-TE 底层的快递段。
在 中 图 1，域 2 利用其 RSVP-TE 底层 LSP 进行流量工程管理，并将这些底层 RSVP-TE LSP 作为快速分段呈现到相邻域（域 1 和域 3），从而实现端到端 SR-TE 路径建立。
图 1： 带 RSVP 底层的多域端到端 SR-TE
-
Express 段通过将 SR 段列表（区段列表）压缩为每个域至少一个段 ID （SID）/标签，隐式减小了 SR 段列表的大小。当端到端流量工程约束会导致分段列表超出入口路由器的标签施加能力时，此功能非常有用。当一个或多个域已经在实施 SR-TE 进行流量工程路径管理时，这也变得有益。
在 中 图 2，您可以看到域 2 正在使用 SR-TE，以及快速分段的使用如何使 PE1 设备使用三个标签（而不是五个）遍历多域网络。
图 2： 标签堆栈减少的多域端到端 SR-TE
-
Express 段允许运营商向相邻域和/或更高层系统呈现网络的抽象。
要通过一系列互连域或多域网络建立流量工程路径，需要对每个网络域具有一定数量的流量工程信息。拓扑抽象允许使用策略进行跨域连接。拓扑抽象不一定提供所有可能的连接选项，而是根据确定需要使用域资源的策略提供潜在连接的视图。该域可以构造为边界节点到边界节点快速段的网格。
使用 ，PE2 图 2的端到端流量工程系统的视图在其本地流量工程数据库中表示，如 所示 图 3。
图 3： 抽象流量工程域
用例
本节介绍建立端到端 SR-TE 连接的几个用例。RFC7926 引入了一套全面的术语和用例，以及一个架构，以促进域之间的流量工程链路和节点信息交换。随着服务提供商的网络因持续增长而不断扩展，多域网络变得越来越普遍。在这些多域网络中，需要在一个或多个域之间建立从源到目标的端到端流量工程路径
使用 Express 分段的域内和域间 SR-TE 连接
Express 分段能够在域之间发生路由信息交换时抽象流量工程信息。用作路径选择标准的流量工程信息是与流量工程节点和链路相关的数据。流量工程信息可以是 IGP、流量工程、延迟等链路指标，也可以是关联性等管理链路属性。最好将快速分段描述为虚拟流量工程链路，以促进底层 LSP 的抽象。
增强型按需下一跃点
增强型按需下一跃点 （EODN）（也称为 BGP 触发的 SR 策略）有助于在服务路由到达时动态配置端到端 SR-TE 策略，但有限制。在拥有数百台 PE 设备的大型网络中，为每个出口 PE 在任何入口 PE 上创建和维护流量工程策略是一项挑战。考虑特定于颜色的服务（每个 VPN 或每个前缀组）会使事情变得更加复杂，更难维护和故障排除。BGP 触发的 SR-TE 通过基于预配置模板自动创建动态 SR 隧道来解决任务。无需为每个出口 PE 配置入口 PE。
快递网段如何运作？
Express 分段可用于在互连的流量工程网络之间建立端到端流量工程路径。Express 分段（也称为虚拟流量工程链路）通过与底层 LSP 匹配的策略动态生成。使用策略生成快速分段和相应的抽象拓扑（ RFC7926 需要）。
要应用策略，请在 [edit protocols express-segment traffic-engineering] 层次结构级别包含policy policy-name配置语句。
注：
这是 policy-name 可选的。如果未定义策略名称，则该策略会将所有快速段隐式导入到本地流量工程数据库中。快速段模板会自动创建快速链接的一对一映射。
要配置快速分段，请在 [edit protocols] 层次结构级别下包含express-segment配置语句。
让我们参考 图 1 并使用在 C1 和 C4 边界节点之间显示的一对 RSVP-TE LSP，以及如何生成表示底层 LSP 的快速段。在 中 图 4，将创建一个策略以将两个 RSVP-TE（黄金和液金）LSP 表示为单个快递段。
图 4： 一对表示为快速分段的 RSVP-TE LSP
下面是一个示例策略，其中的策略名称通过正则表达式和 RSVP-TE LSP 的端点进行匹配：
protocols {
express-segment-set gold-exp-seg {
policy gold;
}
}
policy-options {
policy-statement gold {
from {
route-filter 10/8 {
install-next-hop lsp-regex *gold;
}
}
then accept;
}
}
在以下示例输出中，您可以看到新创建的快速分段 （Gold-Exp-Set-192.168.1.4） 以及信息流工程属性继承自底层 RSVP-TE 隧道：
user@C1#show express-segments name gold-exp-seg-192.168.1.4 detail

RSVP-LSP C1_to_C4_liquid_gold
TE-Metric: 30, IGP-Metric: 30

您可以在输出中观察到以下内容：
-
快速段的自动命名 （
Gold-Exp-Set-192.168.1.4）。 -
底层 RSVP-LSP 的信息流工程属性（带宽、指标、管理员组、SRLG）由快速分段继承。
-
Express 段是一个未编号的流量工程链路，已添加到流量工程数据库中。
-
标签 19 已分配并安装在
mpls.0转发表中，作为 SR 虚拟流量工程链路的邻接 SID。
以下是 SR-TE LSP 目标匹配的示例：
protocols {
express-segments {
segment-set set1sr {
membership-policy expresspolsr1;
}
traffic-engineering;
}
policy-options {
policy-statement expresspolsr1 {
from {
protocol spring-te;
route-filter 3.3.3.3/32 exact;
}
then accept;在以下示例输出中，您可以看到从未着色的 SR-TE 底层隧道新创建的快速分段 （set1sr-3.3.3.3）：
user@C1show express-segments detail Name: set1sr-3.3.3.3 To: 3.3.3.3, Type: Dynamic (Set: set1sr) Label: 16 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 5d 20:37:08) LinkAttributes: LocalID: 2147483649 TE-Metric: 20, IGP-Metric: 20 BW: 0bps UnderlayPaths: 1 SRTE LSP: lsp1to3_sr TE-Metric: 0, IGP-Metric: 0 BW: 0bps
如何宣传快递段？
Express 分段会使用 BGP 链路状态跨域边界或通告到更高级别的控制器和路径计算元素 （PCE）。通过 BGP 链路状态交换信息时，BGP 链路状态的扩展用于将快速分段通告为流量工程链路。快速分段流量工程链路和其他正常流量工程链路出现在网络中任何 LSR 的流量工程链路状态数据库中，用于计算端到端流量工程路径。通过 BGP 链路状态，使用以量工程数据库导入和导出配置，从表 f或通告导入lsdist.0和导出快速分段流量工程数据库条目：
protocols {
mpls {
traffic-engineering {
database {
import {
l3-unicast-topology {
bgp-link-state;
}
policy es_2_bgpls;
}
export {
policy bgpls_2_ted;
}
}
}
}
bgp {
group te-peers {
family traffic-engineering {
unicast;
}
export abstract-topo;
}
}
}
图 5 直观地表示了流量工程链路和节点在本地流量工程数据库与 lsdist.0 BGP-LS 用于播发的 RIB 之间的镜像方式。如图所示，有几个策略连接点。
图 5： 广告快递段
路径计算元素如何使用快速段？
BGP 链路状态导出策略是创建抽象或自定义拓扑以播发至流量工程对等方的有效位置。例如，您可能只想将快速分段和域 3 的 TE 链路和节点播发到 PE2，以便抽象化流量工程拓扑，如 中 图 6所示。然后，PE2 使用抽象视图进行端到端路径计算。
图 6： 使用快速分段抽象流量工程域 2
以下是 C1 上的 BGP 链路状态导出策略的示例配置：
policy-options {
policy-statement abstract-topo {
from {
traffic-engineering {
protocol express-segment;
ipv4-prefix {
as 3;
}
}
}
then accept;
}
}
以下是 PE2 路由器上用于建立从 PE2 到 PE3 的端到端多域路径的 SR 策略配置示例：
protocols {
source-packet-routing {
source-routing-path pe2-to-pe3 {
to 192.168.70.1;
color 10;
primary {
sl1 {
compute {
profile_any-path;
}
}
}
}
}
}
生成的端到端路径在 中 图 7表示。您可以看到 SR 分段列表中使用了快速分段的邻接 SID（标签 19），从而在域 2 中的黄金和液金 RSVP-TE LSP 上对流量进行了负载平衡。

概述
以下拓扑 （图 8） 显示了通过 RSVP-TE （AS200） 域互连运行 EBGP-LS 的两个 SR-TE 域（AS100 和 AS300）：
拓扑学
图 8： 使用 Express 分段的域间 SR-TE 连接
在此拓扑中，在 PE1 路由器到 PE2 路由器之间建立了端到端 SR-TE 路径。出口对等工程 （EPE） 分段在 PE1 和 PE2 路由器上定义，以分别将流量引导至其直接连接的边界节点 BN1/BN2 和 BN3/BN4。在边界节点上定义的 EPE 分段通过 BGP 链路状态在内部播发。这两个 SR-TE 域通过利用 RSVP-TE LSP 建立内部路径的域 （AS200） 互连。
AS200 域的边界节点便于在域之间抽象 SR-TE 信息。在边界节点（BN1、BN2、BN3 和 BN4）上创建快速段。将以与底层 RSVP-TE LSP 一对一的关系创建快速分段，并将所有快速分段插入到边界节点的本地 TE 数据库中，以供后续 BGP 链路状态通告使用。AS200 域利用 RSVP-TE LSP 底层进行 TE 管理，并将这些底层 RSVP-TE LSP 作为快速网段呈现给 AS100 和 AS300 域，使域能够实现端到端的 SR-TE LSP 连接。

验证
要确认配置工作正常，请执行以下任务：
验证快速网段
目的
验证是否正确创建了快速段。
操作
在操作模式下，运行以下命令：
-
show express-segments detail- 验证是否已创建快速段。 -
show ted database topology-type express-segments detail- 验证新创建的快速段是否已插入到 TE 数据库中。 -
show route table mpls.0 protocol express-segments- 验证是否已创建转发条目。
user@R1>show express-segments detail Name: r1-exp-set1-10.6.6.6 To: 10.6.6.6, Type: Dynamic (Set: r1-exp-set1) Label: 25 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 09:32:00) LinkAttributes: LocalID: 2147483686 TE-Metric: 200*, IGP-Metric: 100* BW: 0bps AdminGroups: red* UnderlayPaths: 1 RSVP LSP: lsp1to6_a TE-Metric: 29, IGP-Metric: 20 BW: 0bps AdminGroups: brown red Name: r1-exp-set2-10.3.3.3 To: 10.3.3.3, Type: Dynamic (Set: r1-exp-set2) Label: 24 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 09:32:00) LinkAttributes: LocalID: 2147483685 TE-Metric: 19, IGP-Metric: 20 BW: 0bps AdminGroups: brown red UnderlayPaths: 1 RSVP LSP: lsp1to3_a TE-Metric: 19, IGP-Metric: 20 BW: 0bps AdminGroups: brown red
在 R1 上
user@R1>show ted database topology-type express-segments detail TED database: 0 ISIS nodes 4 INET nodes 0 INET6 nodes NodeID: 10.1.1.1 Type: Rtr, Age: 119174 secs, LinkIn: 0, LinkOut: 3 Protocol: EXPRESS-SEG(0) To: 10.3.3.3, Local: 10.1.1.1, Remote: 10.3.3.3 Local interface index: 2147483685, Remote interface index: 0 Link name: r1-exp-set2-10.3.3.3 To: 10.6.6.6, Local: 10.1.1.1, Remote: 10.6.6.6 Local interface index: 2147483686, Remote interface index: 0 Link name: r1-exp-set1-10.6.6.6 NodeID: 10.3.3.3 Type: Rtr, Age: 34364 secs, LinkIn: 1, LinkOut: 0 Protocol: EXPRESS-SEG(0) NodeID: 10.6.6.6 Type: Rtr, Age: 34364 secs, LinkIn: 1, LinkOut: 0 Protocol: EXPRESS-SEG(0)
在 R1 上
user@R1>show route table mpls.0 protocol express-segments mpls.0: 13 destinations, 13 routes (13 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 24 *[EXPRESS-SEG/6] 09:33:24, metric 1 > to 192.168.3.2 via ge-0/0/2.0, Swap 33 25 *[EXPRESS-SEG/6] 09:33:24, metric 1 > to 192.168.3.2 via ge-0/0/2.0, Swap 34
意义
-
在输出中
show express-segments detail，您可以看到快速段 （r1-exp-set1-10.6.6.6, r1-exp-set2-10.3.3.3）、快速段标签 （25, 24） 和底层 LSP （lsp1to6_a, lsp1to3_a） 的名称。 -
在输出中
show ted database topology-type express-segments detail，您可以看到快速段条目已插入到 TE 数据库中。快速网段（虚拟 TE 链路）是动态创建的。使用的协议是 EXPRESS-SEG(0)。 -
在输出中
show route table mpls.0 protocol express-segments，您可以看到快速段标签 （24,25）。由于快速分段是依赖于底层 LSP 的构造，因此快速分段标签将交换到底层 LSP 标签 （33,34），即 RSVP-LSP。
验证快速网段播发
目的
验证始发节点是否将快速分段通告至其 eBGP/iBGP LS 邻接方。
操作
在操作模式下，运行以下命令：
-
show route table lsdist.0- 验证 RIB BGP-LS 中的快速段是否正在播发。 -
show route advertising-protocol bgp neighbor— 验证快速分段是否已发送到 eBGP/iBGP LS 邻居。
user@R1>show route table lsdist.0
lsdist.0: 25 destinations, 37 routes (25 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

意义
-
在输出中
show route table lsdist.0，BGP 通告路由表中的路由。路由表是从 TE 数据库创建的。您可以看到快速段 （EXPRESS-SEG/6） 链接和 EPE 链接 （BGP-LS-EPE:0 }/1216）。 -
在输出中
show route advertising-protocol bgp 10.2.2.2，您可以看到 R1 播发的目标。快速段入到 TE 数据库中，该数据库被复制到 RIB。BGP-LS 将 RIB 播发至对等路由器。在对等体上，收到的 RIB 信息被复制到本地数据库中。此示例中的策略仅播发快速网段和 EPE 网段。
验证 TE 拓扑信息
目的
验证入口节点是否通过 eBGP/iBGP LS 接收 TE 拓扑信息。
操作
在操作模式下，运行以下命令：
-
show route receive-protocol bgp neighbor— 验证是否从 eBGP/iBGP LS 邻居接收了快速分段。 -
show route table lsdist.0- 验证快速段是否在 BGP-LS RIB 中。 -
show ted database topology-type l3-unicast detail— 验证快速分段是否已导入入口路由器的 TE 数据库。 -
show spring-traffic-engineering lsp— 验证是否已成功计算并安装端到端 SR 策略。

概述
以下拓扑 （图 9） 显示了运行 EBGP-LS 的两个 SR-TE 域（AS100 和 AS300）通过另一个 SR-TE （AS200） 域互连：
拓扑学
图 9： 通过 SR-TE 底层使用 快速分段的域间 SR-TE 连接
在此拓扑中，在 PE1 路由器到 PE2 路由器之间建立了端到端 SR-TE 路径。出口对等工程 （EPE） 分段在 PE1 和 PE2 路由器上定义，以分别将流量引导至其直接连接的边界节点 BN1/BN2 和 BN3/BN4。在边界节点上定义的 EPE 分段通过 BGP 链路状态在内部播发。这两个 SR-TE 域通过利用 SR-TE LSP 建立内部路径的域 （AS200） 互连。
AS200 域的边界节点便于在域之间抽象 SR-TE 信息。在边界节点（BN1、BN2、BN3 和 BN4）上创建快速段。在与底层 SR-TE LSP 一对一的关系中创建快速分段，并将所有快速分段插入到边界节点的本地 TE 数据库中，以供后续 BGP 链路状态通告使用。AS200 域利用 SR-TE LSP 底层进行 TE 管理，并将这些底层 SR-TE LSP 作为快速网段呈现给 AS100 和 AS300 域，使域能够实现端到端 SR-TE LSP 连接。

配置 R0（PE1 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R0：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R0#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-
配置接口以启用 IP、MPLS 和 ISO 传输。

配置 R1（BN1 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R1：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R1#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-
配置接口以启用 IP、MPLS 和 ISO 传输。

配置 R4（BN2 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R4：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R4#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-
配置接口以启用 IP、MPLS 和 ISO 传输。

配置 R5（中间路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R5：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R5#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。

配置 R3（BN3 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R3：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R3#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-
配置接口以启用 IP、MPLS 和 ISO 传输。

配置 R6（BN4 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R6：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R6#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-
配置接口以启用 IP、MPLS 和 ISO 传输。

配置 R7（PE2 路由器）
分步过程
下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置设备 R7：
-
将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。
[edit] user@R7#set chassis network-services enhanced-ip
配置
enhanced-ip语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
重新启动将显示路由器上的 FPC。
-

验证
要确认配置工作正常，请执行以下任务：
验证快速网段
目的
验证是否正确创建了快速段。
操作
在操作模式下，运行以下命令：
-
show express-segments detail- 验证是否已创建快速段。 -
show ted database topology-type express-segments detail- 验证新创建的快速段是否已插入到 TE 数据库中。 -
show route table mpls.0 protocol express-segments- 验证是否已创建转发条目。
user@R1>show express-segments detail Name: set1sr-10.3.3.3 To: 10.3.3.3, Type: Dynamic (Set: set1sr) Label: 16 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 5d 20:37:08) LinkAttributes: LocalID: 2147483649 TE-Metric: 20, IGP-Metric: 20 BW: 0bps UnderlayPaths: 1 SRTE LSP: lsp1to3_sr TE-Metric: 0, IGP-Metric: 0 BW: 0bps
在 R1 上
user@R1>show ted database topology-type express-segments detail TED database: 18 ISIS nodes 7 INET nodes 0 INET6 nodes NodeID: R1.00(10.1.1.1) Type: Rtr, Age: 774 secs, LinkIn: 4, LinkOut: 6 Protocol: EXPRESS-SEG(0) To: R3.00(10.3.3.3), Local: 10.1.1.1, Remote: 10.3.3.3 Local interface index: 2147483649, Remote interface index: 0 Link name: set1sr-10.3.3.3 NodeID: R3.00(10.3.3.3) Type: Rtr, Age: 580 secs, LinkIn: 4, LinkOut: 3 Protocol: EXPRESS-SEG(0)
在 R1 上
user@R1>show route table mpls.0 protocol express-segments
mpls.0: 33 destinations, 33 routes (33 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
16 *[EXPRESS-SEG/6] 5d 14:13:37, metric 1
> to 192.168.3.2 via ge-0/0/2.0, Swap 801003
to 192.168.21.2 via ge-0/0/2.1, Swap 801003意义
-
在输出中
show express-segments detail，您可以看到快速段 （set1sr-10.3.3.3）、快速段标签 （16） 和底层 LSP （lsp1to3_sr） 的名称。 -
在输出中
show ted database topology-type express-segments detail，您可以看到快速段条目已插入到 TE 数据库中。快速网段（虚拟 TE 链路）是动态创建的。使用的协议是 EXPRESS-SEG(0)。 -
在输出中
show route table mpls.0 protocol express-segments，您可以看到快速段标签 （16）。由于快速分段是依赖于底层 LSP 的构造，因此快速分段标签将交换到底层 SR-TE 标签 （801003）。
验证快速网段播发
目的
验证始发节点是否将快速分段通告至其 eBGP/iBGP LS 邻接方。
操作
在操作模式下，运行以下命令：
-
show route table lsdist.0- 验证 RIB BGP-LS 中的快速段是否正在播发。 -
show route advertising-protocol bgp neighbor— 验证快速分段是否已发送到 eBGP/iBGP LS 邻居。
user@R1>show route table lsdist.0
lsdist.0: 23 destinations, 40 routes (23 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

意义
-
在输出中
show route table lsdist.0，BGP 通告路由表中的路由。路由表是从 TE 数据库创建的。您可以看到快速段 （EXPRESS-SEG/6） 链接和 EPE 链接 （BGP-LS-EPE:0 }/1216）。 -
在输出中
show route advertising-protocol bgp 10.2.2.2，您可以看到 R1 播发的目标。快速段入到 TE 数据库中，该数据库被复制到 RIB。BGP-LS 将 RIB 播发至对等路由器。在对等体上，收到的 RIB 信息被复制到本地数据库中。此示例中的策略仅播发快速网段和 EPE 网段。
验证 TE 拓扑信息
目的
验证入口节点是否通过 eBGP/iBGP LS 接收 TE 拓扑信息。
操作
在操作模式下，运行以下命令：
-
show route receive-protocol bgp neighbor— 验证是否从 eBGP/iBGP LS 邻居接收了快速分段。 -
show route table lsdist.0- 验证快速段是否在 BGP-LS RIB 中。 -
show ted database topology-type l3-unicast detail— 验证快速分段是否已导入入口路由器的 TE 数据库。 -
show spring-traffic-engineering lsp— 验证是否已成功计算并安装端到端 SR 策略。
