示例：使用 MLDP 点对多点提供商隧道在 BGP MVPN 中配置基于发送方的 RPF
此示例说明如何在 BGP 组播 VPN （MVPN） 中配置基于发送方的反向路径转发 （RPF）。基于发送方的 RPF 有助于防止多个提供商边缘 （PE） 路由器将流量发送到核心，从而防止向客户发送重复流量。
要求
配置此示例之前，不需要除设备初始化之外的特殊配置。
具有 MPC 线卡的 MX 系列平台支持基于发送方的 RPF。作为先决条件，路由器必须设置为 network-services enhanced-ip 模式。
只有具有 RSVP-TE 点对多点提供商隧道的 MPLS BGP MVPN 才支持基于发送方的 RPF。仅 SPT 和 SPT-RPT MVPN 模式均受支持。
当点对多点提供商隧道与标签交换接口 （LSI） 一起使用时，基于发送方的 RPF 不起作用。Junos OS 仅为每个 VRF 分配一个 LSI 标签，并将此标签用于所有点对多点隧道。因此，出口接收的标签不指示发送 PE 路由器。LSI 标签目前无法扩展以为每个点对多点隧道创建唯一的标签。因此，虚拟隧道接口 （vt） 必须用于通过点对多点提供商隧道实现基于发送方的 RPF 功能。
此示例要求在启用了基于发送方的 RPF 的 PE 路由器上安装 Junos OS 21.1R1 或更高版本。
概述
此示例显示单个自治系统（AS 内部场景），其中一个源将组播流量（组 224.1.1.1）发送到 VPN（VRF 实例 vpn-1）。两个接收器订阅该组。它们分别连接到设备 CE2 和设备 CE3。在 PE 路由器之间设置具有包容性提供商隧道的 MLDP 点对多点 LSP。PIM （C-PIM） 在 PE-CE 链路上配置。
对于 MPLS，此处使用的信令控制协议是 LDP。或者，您可以使用 RSVP 向点对点和点对点隧道发出信号。
OSPF 用于内部网关协议 （IGP） 连接，但 IS-IS 也是受支持的选项。如果使用 OSPF，则必须启用 OSPF 流量工程。
出于测试目的，路由器用于模拟源和接收器。设备 PE2 和设备 PE3 配置为使用命令静态 set protocols igmp interface interface-name static group 224.1.1.1 加入 224.1.1.1 组。如果真正的组播接收器主机不可用（如本例所示），此静态 IGMP 配置非常有用。在连接到接收方的 CE 设备上，要使它们侦听组播组地址，此示例使用 set protocols sap listen 224.1.1.1.ping 命令用于将组播流量发送到 BGP MBPN。
设备 PE2 上启用了基于发送方的 RPF，如下所示：
[routing-instances vpn-1 protocols mvpn] user@PE2# set sender-based-rpf
您可以选择使用 进行sender-based-rpf配置 hot-root-standby .

配置设备 PE2
程序
分步过程
以下示例要求您在配置层次结构中导航各个级别。有关导航 CLI 的信息，请参阅《Junos OS CLI 用户指南》中的在配置模式下使用 CLI 编辑器。
要配置设备 PE2：
-
启用增强型 IP 模式。
[edit chassis] user@PE2# set network-services enhanced-ip
-
配置设备接口。
[edit interfaces] user@PE2# set ge-1/2/12 unit 0 family inet address 10.1.1.10/30 user@PE2# set ge-1/2/12 unit 0 family mpls user@PE2# set ge-1/2/14 unit 0 family inet address 10.1.1.17/30 user@PE2# set ge-1/2/14 unit 0 family mpls user@PE2# set vt-1/2/10 unit 4 family inet user@PE2# set lo0 unit 0 family inet address 10.1.1.4/32 user@PE2# set lo0 unit 104 family inet address 10.100.1.4/32
-
在面向客户边缘的接口上配置 IGMP。
[edit protocols igmp] user@PE2# set interface ge-1/2/14.0
-
（可选）强制 PE 设备加入具有静态配置的组播组。
通常，这将在具有真实源和接收器的设置中动态发生。
[edit protocols igmp] user@PE2# set interface ge-1/2/14.0 static group 224.1.1.1
-
在面向提供商核心的接口上配置 RSVP。
[edit protocols rsvp] user@PE2# set interface ge-1/2/0.10
-
配置 MPLS。
[edit protocols mpls] user@PE2# set traffic-engineering bgp-igp-both-ribs user@PE2# set label-switched-path p2mp-template template user@PE2# set label-switched-path p2mp-template p2mp user@PE2# set interface ge-1/2/12.0
-
在 PE 路由器之间配置内部 BGP （IBGP）。
[edit protocols bgp group ibgp] user@PE2# set type internal user@PE2# set local-address 10.1.1.4 user@PE2# set family inet unicast user@PE2# set family inet-vpn any user@PE2# set family inet-mvpn signaling user@PE2# set neighbor 10.1.1.2 user@PE2# set neighbor 10.1.1.5
-
配置 OSPF 或 IS-IS。
[edit protocols ospf] user@PE2# set traffic-engineering user@PE2# set area 0.0.0.0 interface lo0.0 passive user@PE2# set area 0.0.0.0 interface ge-1/2/12.0
-
（可选）配置 LDP。
RSVP 可以用于 MPLS 信令。
[edit protocols bgp group ibgp] user@PE2# set interface ge-1/2/12.0 user@PE2# set p2mp
-
配置要在 VPN 中使用的路由策略。
该策略用于将 BGP 导出到 PE-CE IGP 会话中。
[edit policy-options policy-statement parent_vpn_routes] user@PE2# set from protocol bgp user@PE2# set then accept
-
配置路由实例。
[edit routing-instances vpn-1] user@PE2# set instance-type vrf user@PE2# set interface vt-1/2/10.4 user@PE2# set interface ge-1/2/14.0 user@PE2# set interface lo0.104
-
配置提供程序隧道。
[edit routing-instances vpn-1 provider-tunnel] user@PE2# set ldp-p2mp user@PE2# set selective group 225.0.1.0/24 source 0.0.0.0/0 ldp-p2mp user@PE2# set selective group 225.0.1.0/24 source 0.0.0.0/0 threshold-rate 0
-
配置 VRF 目标。
在单播 IPv4 路由的环境中，选择
vrf-target有两个含义。首先，VRF 上每个本地获知（在本例中为直接和静态）路由都导出到具有指定路由目标 （RT） 的 BGP。此外，每个已接收的具有该 RT 值的 inet-vpn BGP 路由都将导入到 VRF vpn-1 中。这样做的优点是配置更简单，但在选择和修改导出和导入的路由时灵活性较低。这也意味着 VPN 是全网状的，所有 PE 路由器都相互获取路由，因此中心辐射型或外联网等复杂配置不可行。如果需要这些功能中的任何一个，则必须使用vrf-import和vrf-export代替。[edit ] user@PE2# set routing-instances vpn-1 vrf-target target:100:10
-
配置 PE-CE OSPF 会话。
[edit routing-instances vpn-1 protocols ospf] user@PE2# set export parent_vpn_routes user@PE2# set area 0.0.0.0 interface lo0.104 passive user@PE2# set area 0.0.0.0 interface ge-1/2/14.0
-
配置 PE-CE PIM 会话。
[edit routing-instances vpn-1 protocols pim] user@PE2# set rp static address 10.100.1.2 user@PE2# set interface ge-1/2/14.0 mode sparse
-
启用 MVPN 模式。
rpt-spt基于发件人的 RPF 支持这两种方法spt-only。[edit routing-instances vpn-1 protocols mvpn] user@PE2# set mvpn-mode rpt-spt
-
启用基于发件人的 RPF。
[edit routing-instances vpn-1 protocols mvpn] user@PE2# set sender-based-rpf
-
配置路由器 ID、路由器识别符和 AS 编号。
[edit routing-options] user@PE2# set router-id 10.1.1.4 user@PE2# set route-distinguisher-id 10.1.1.4 user@PE2# set autonomous-system 65001

意义
设备 CE2 和设备 CE3 都将 C-Join 数据包上游发送到其相邻的 PE 路由器，即其单播下一跃点以到达 C 源。
C 联接状态指向 BGP 作为上游接口。实际上，PE 之间不存在 PIM 邻居关系。下游 PE 将 C-PIM （C-S， C-G） 状态转换为 7 类源树加入 BGP 路由，并将其发送到朝向 C 源的上游 PE 路由器。
检查组播路由
目的
确保 C 组播流已集成在 MVPN vpn-1 中，并由设备 PE1 发送到提供商隧道。

意义
输出显示，与其他 PE 设备不同，设备 PE2 使用的是基于发送方的 RPF。设备 PE2 上的输出包括上游 RPF 发送方。“发件人 ID”字段仅在启用基于发件人的 RPF 时显示。
