组网需求
如图所示，为了实现通过骨干网使不同Site间相互通信，可以在网络中配置EVPN和VPN功能，实现二层流量及三层流量业务的传输。当Site之间为同一子网时，各个PE设备上创建EVPN实例，存储EVPN路由，匹配MAC信息进行二层转发；当Site之间为不同子网时，各个PE设备上创建VPN实例，存储VPN路由，终结二层流量，通过三层网关进行三层转发。本例中PE之间将使用SR-MPLS TE隧道承载业务流量的传输。
配置思路
采用如下的思路进行配置：
配置IGP实现PE1、 PE2以及P设备之间的互通。
配置骨干网上的SR-MPLS TE隧道。
配置PE上的EVPN和VPN实例。
配置PE上的源地址。
配置PE与CE相连的二层以太子接口。
配置PE上的Vbdif接口绑定VPN实例。
配置并应用隧道策略，使EVPN可以迭代SR-MPLS TE隧道。
配置PE间的BGP EVPN对等体关系。
配置CE与PE之间相互通信。
操作步骤
步骤1 按图配置PE和P设备之间的接口地址

[*PE2] commit配置完成后， PE1、 PE2和P之间应能建立IS-IS邻居关系，执行display isis peer命令可以看到邻居状态为Up。执行display ip routing-table命令可以看到PE之间学习到对方的Loopback1路由。
