介绍在EVPN组网中，EVPN路由通过迭代静态SR-MPLS TE Policy承载流量的配置过程。

组网需求

如图2-27所示，PE1、P1、P2和PE2属于同一自治系统，要求它们之间通过IS-IS协议达到网络互连的目的。在PE1和PE2上通过配置SR-MPLS TE Policy实现迭代SR隧道承载EVPN业务的目的。

图2-27 EVPN迭代静态SR-MPLS TE Policy组网图

本例中interface1、interface2、interface3分别代表GE0/1/0、GE0/2/0、GE0/3/0。

配置注意事项

在配置过程中，需注意以下事项：

PE与CE相连的接口绑定了VPN实例后，将删除该接口上已经配置的IP地址、路由协议等三层特性，如果需要应重新配置。

配置思路

采用如下的思路配置EVPN迭代静态SR-MPLS TE Policy：

在各个设备上配置接口IP地址。
在各个设备上配置IGP协议，实现骨干网PE和P的互通。本例中以IS-IS为例进行说明。
在各个设备上使能MPLS，配置Segment Routing和静态邻接标签。
在PE上配置SR-MPLS TE Policy，SR-MPLS TE Policy配置路径信息。
在PE上配置SBFD和HSB功能，增强SR-MPLS TE Policy可靠性。
在PE之间建立BGP EVPN对等体关系，同时应用入口策略，为路由添加扩展团体属性Color。
PE之间配置MP-IBGP交换路由信息。
PE上配置使能IPv4地址族VPN实例，并把与CE相连的接口和相应的VPN实例绑定。
在PE设备上配置隧道选择策略。
CE与PE之间配置EBGP交换路由信息。

数据准备

为完成此配置例，需准备如下的数据：

PE及P上的MPLS LSR-ID。
EVPN实例evrf1和L3VPN实例vpn1的VPN-Target和RD。

操作步骤

在各个设备上配置接口IP地址。
