示例:配置多实例 LDP
主 LDP 实例在层次结构级别进行 [edit protocols]
配置。
您可以使用层次结构级别的语句[edit routing-instances routing-instance-name protocols]
来ldp
配置 LDP 的特定实例。这将为特定 VRF 路由实例创建 LDP 实例。您必须指定所有必需的 VRF 语句,并将导出和导入策略应用于 LDP 实例,才能正确提交配置。
主实例中可用的大多数 LDP 层次结构级别也可用于 LDP 的特定实例。但是,该 no-forwarding
选项在基于 VRF 的 LDP 实例中不起作用。
图 1 显示了载波网络的示例。CE3 和 CE4 是驻留在 AS 65010 中的最终客户客户边缘路由器。AS 65020 中的 VPN 提供商有三种类型的路由器:PE3 和 PE4 是连接到最终客户的 PE 路由器,CE1 和 CE2 充当中间运营商 客户边缘 路由器,P2 和 P3 是内部传输路由器。AS 65030 中的 PE1 和 PE2 是服务于中间 VPN 提供商的 PE 路由器,P0 和 P1 是顶级运营商的中转路由器。
若要使此配置正常工作,必须完成三个主要任务:
-
在 VPN 客户客户边缘和 VPN 提供商 PE 之间配置外部 BGP。
-
使用两对 PE 路由器之间的 VPN 系列配置内部 BGP(PE1 和 PE2 之间的一个 IBGP 连接,路由器 PE3 和路由器 PE4 之间的第二个 IBGP 连接)。
-
在所有剩余链路上建立 LDP 和内部网关协议 (IGP) 连接。此示例使用 OSPF 作为 IGP,但您可以使用自己选择的 IGP。

您的配置任务从路由器 CE3 开始,逐个路由器通过 VPN 提供商网络的第一部分,通过 AS 65020 的第二个 VPN 提供商集群进入运营商 AS,最后到第二个 VPN 客户路由器 CE4 结束。
由于路由器 CE3 是第一个客户路由器,因此请在路由器 CE3 和连接的 VPN 提供商路由器 PE3 之间配置 EBGP。您还必须使用路由策略将您的环路地址播发到 BGP 中,以允许路由器 CE4 的 IP 可访问性。

在路由器 PE3 上,配置任务更为复杂。您需要在 VRF 实例中完成与路由器 CE3 的 EBGP 连接,在指向 VPN 提供商路由器 CE1 的接口上启用 MPLS 和 LDP,并配置 IBGP 的主实例以访问位于 AS 65020 远端边缘的路由器 PE4。
最后,设置出站 VRF 策略,将所有 BGP 流量和直接连接的接口放入 BGP 社区,并设置入站 VRF 策略,接受来自路由器 PE4 的类似 BGP 社区流量。

在路由器 P2 上,启用 LDP 和用于传输标签的 IGP(在本例中为 OSPF)。您将在 VPN 提供商网络和核心运营商网络中的所有传输核心路由器上重复这些任务。

在核心运营商路由器 PE1 上,为 OSPF、LDP、MPLS 和 IBGP 配置主实例(带 family inet-vpn
选项),以将路由器连接到邻居路由器 PE2。接下来,通过建立辅助实例来实现多实例 LDP。在这种情况下,为路由器 PE1 启用 LDP 和 OSPF 以与路由器 CE1 通信。辅助实例中不需要 MPLS。
最后,设置一个出站 VRF 策略,用于将来自路由器 CE1 的所有 LDP 流量放入 BGP 社区,设置一个将此社区流量发送到路由器 PE2 的导出策略,以及一个接受来自路由器 PE2 的类似 BGP 社区流量的入站 VRF 策略。此步骤将 VPN 提供商的 LDP 流量通过隧道进入运营商的 BGP 会话。

验证您的工作
要验证多实例 LDP 配置是否正确运行,请使用以下命令:
-
show ldp database
-
show ldp interface
-
show ldp neighbor
-
show ldp path
-
show ldp route
-
show ldp session
-
show ldp statistics
这些命令的显示输出与以前的 Junos OS 版本中相同,但有一个区别。实例名称现在可以用作参数。
如果在这些命令中包含实例名称,则会显示指定 LDP 实例的信息。例如,该命令 show ldp neighbor instance crockett
显示名为 的 crockett
VRF 实例的所有 LDP 邻居。相反,如果没有实例名称, show ldp neighbor
则会显示与主实例关联的 LDP 邻居。
以下部分显示了与配置示例一起使用的这些命令的输出:
