示例：为 OSPF 或 OSPF3 协议配置备份选择策略
此示例说明如何为 OSPF 或 OSPF3 协议配置备份选择策略，以便选择网络中的无环路备用 （LFA）。
启用备份选择策略时，Junos OS 允许根据网络中链路和节点的策略规则和属性选择 LFA。这些属性包括管理员组、srlg、带宽、保护类型、指标和节点。
要求
此示例使用以下硬件和软件组件：
八款路由器，可以是 M 系列多服务边缘路由器、MX 系列 5G 通用路由平台、PTX 系列数据包传输路由器和 T 系列核心路由器的组合
在所有设备上运行的 Junos OS 15.1 或更高版本
准备工作：
配置设备接口。
配置 OSPF。
概述
在 Junos OS 中，可以使用 LFA 策略覆盖默认的无环路备选 （LFA） 选择算法或标准。这些策略是针对每个目标（IPv4 和 IPv6）和下一跃点主接口配置的。这些备份策略根据备份路径的管理员组、srlg、带宽、保护类型、指标和节点属性强制执行 LFA 选择。在备份最短路径优先 （SPF） 计算期间，IGP 会累积备份路径的每个属性（节点和链路）（按备份下一跃点存储）。对于 IGP 在内部创建的路由，将根据为每个目标（IPv4 和 IPv6）和主下一跃点接口配置的策略评估每个备份路径的属性集。选择第一个或最佳备份路径并将其安装为路由表中的下一备份跃点。要配置备份选择策略，请在层次结构级别包含 配置语句 。backup-selection[edit routing-options] 该 命令显示为给定接口和目标配置的策略。show backup-selection 可以根据特定目标、前缀、接口或逻辑系统过滤显示内容。
配置
CLI 快速配置
要快速配置此示例，请复制以下命令，将其粘贴到文本文件中，删除所有换行符，更改详细信息，以便与网络配置匹配，将命令复制并粘贴到 [edit] 层级的 CLI 中，然后从配置模式进入 commit 。

配置路由器的 ID。
[edit routing-options] user@R3# set router-id 172.16.3.3
将路由策略应用于从路由表导出到转发表的所有等价多路径。
[edit routing-options] user@R3# set forwarding-table export ecmp
配置备份选择策略的属性。
[edit routing-options backup-selection] user@R3# set destination 10.1.1.0/30 interface xe-1/3/0.0 admin-group include-all c2 user@R3# set destination 10.1.1.0/30 interface all admin-group exclude c3 user@R3# set destination 10.1.1.0/30 interface all srlg strict user@R3# set destination 10.1.1.0/30 interface all protection-type node user@R3# set destination 10.1.1.0/30 interface all bandwidth-greater-equal-primary user@R3# set destination 10.1.1.0/30 interface all neighbor preference 172.16.7.7 user@R3# set destination 10.1.1.0/30 interface all root-metric lowest user@R3# set destination 10.1.1.0/30 interface all metric-order root user@R3# set destination 172.16.30.0/30 interface all admin-group exclude c5 user@R3# set destination 172.16.30.0/30 interface all srlg strict user@R3# set destination 172.16.30.0/30 interface all protection-type node user@R3# set destination 172.16.30.0/30 interface all bandwidth-greater-equal-primary user@R3# set destination 172.16.30.0/30 interface all neighbor preference 172.16.7.7 user@R3# set destination 172.16.30.0/30 interface all root-metric lowest user@R3# set destination 172.16.30.0/30 interface all metric-order root user@R3# set destination 192.168.45.0/30 interface all admin-group exclude c5 user@R3# set destination 192.168.45.0/30 interface all srlg strict user@R3# set destination 192.168.45.0/30 interface all protection-type node user@R3# set destination 192.168.45.0/30 interface all bandwidth-greater-equal-primary user@R3# set destination 192.168.45.0/30 interface all neighbor preference 172.16.7.7 user@R3# set destination 192.168.45.0/30 interface all root-metric lowest user@R3# set destination 192.168.45.0/30 interface all metric-order root
在所有接口上启用 RSVP。
[edit protocols] user@R3# set rsvp interface all
配置管理组。

在所有接口上启用 MPLS 并为接口配置管理组。
[edit protocols mpls] user@R3# set interface all user@R3# set interface ge-0/0/5.0 admin-group c0
在 OSPF 区域的所有接口上启用链路保护并配置指标值。
[edit protocols ospf] user@R3# set area 0.0.0.0 interface ge-0/0/5.0 link-protection user@R3# set area 0.0.0.0 interface ge-0/0/5.0 metric 10 user@R3# set area 0.0.0.0 interface xe-0/3/1.0 metric 21 user@R3# set area 0.0.0.0 interface ge-1/0/0.0 metric 13 user@R3# set area 0.0.0.0 interface ge-1/0/6.0 metric 15 user@R3# set area 0.0.0.0 interface xe-1/3/0.0 link-protection user@R3# set area 0.0.0.0 interface xe-1/3/0.0 metric 22
在 OSPF3 区域的所有接口上启用链路保护并配置衡量指标值。
[edit protocols ospf3] user@R3# set area 0.0.0.0 interface ge-0/0/5.0 link-protection user@R3# set area 0.0.0.0 interface ge-0/0/5.0 metric 10 user@R3# set area 0.0.0.0 interface xe-0/3/1.0 metric 21 user@R3# set area 0.0.0.0 interface ge-1/0/0.0 metric 13 user@R3# set area 0.0.0.0 interface ge-1/0/6.0 metric 15 user@R3# set area 0.0.0.0 interface xe-1/3/0.0 link-protection user@R3# set area 0.0.0.0 interface xe-1/3/0.0 metric 22
