篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了华为运营商级路由器配置示例 | 公网IPv6 over SRv6 TE Policy相关的知识，希望对你有一定的参考价值。
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网络互连的目的。PE1、P和PE2属于IS-IS进程1，都是Level-1设备。PE1与PE2之间部署IBGP邻居，PE和Device之间部署EBGP邻居。
要求在PE1和PE2之间建立双向SRv6 TE Policy路径，承载公网IPv6业务。
图1 配置公网IPv6 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，指定网络实体名称。
- 在PE和Device之间建立EBGP对等体关系。
- 在PE之间建立MP-IBGP对等体关系。
- 在PE1和PE2上配置SRv6 TE Policy；配置IS-IS的SRv6能力。End.DT6 SID采用BGP动态分配。
操作步骤
1.使能各接口的IPv6能力，配置IPv6地址，以PE1为例，其他路由器的配置过程相同，不再赘述
