华为运营商级路由器配置示例 | EVdPdNd VPLS over SRv6 TE Policy（静态配置）
2023-09-14 09:09:07 时间
组网需求
如图1所示：PE1、P和PE2属于同一自治系统，要求它们之间通过IS-IS协议达到IPv6网络互连。然后在PE1和PE2之间通过建立双向SRv6 TE Policy承载EVPN E-LAN业务。
图1 配置EVPN VPLS over SRv6 TE Policy组网图
配置思路
- 使能PE1、P和PE2各接口的IPv6转发能力，配置各接口的IPv6地址。
- 在PE1、P和PE2上使能IS-IS，配置Level级别，指定网络实体。
- 在PE设备上配置BD模式的EVPN实例，并将相应的BD绑定到接入侧子接口。
- 在PE设备之间建立BGP EVPN对等体关系。
- 在PE1、P和PE2上配置SRv6 SID，配置IS-IS的SRv6能力。同时在PE1和PE2上配置VPN私网路由携带SID属性。
- 在PE1和PE2上配置SRv6 TE Policy。
- 在PE1和PE2上配置隧道策略，引入私网流量。
操作步骤
1.使能各接口的IPv6转发能力，配置各接口的IPv6地址
# 配置PE1。P和PE2设备的配置过程与PE1类似，不再赘述，详情可参考配置文件。

[*PE1] commit由于需要为EVPN源地址准备IPv4地址，因此这里Loopback接口还需配置IPv4地址。
2.配置IS-IS
