配置EVPN L3VPNv6 over SR-MPLS TE示例
配置EVPN L3VPNv6迭代SR-MPLS TE隧道承载业务的示例。
配置注意事项
在配置过程中，需注意以下事项：
同一VPN实例的Export VPN-Target列表与其它站点的Import VPN-Target列表有共同的VPN-Target，Import VPN-Target列表与其它站点的Export VPN-Target列表有共同的VPN-Target；
PE上配置的源地址建议为本地Loopback地址。
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IPv6 VPN实例以及接口绑定IPv6 VPN实例。
配置PE间的BGP EVPN对等体关系。
配置并应用隧道策略，使EVPN可以迭代SR-MPLS TE隧道。
配置PE与CE间的私网BGP邻居关系。
操作步骤
- 配置各个设备的接口地址
