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NE40E路由器实验配置示例 | 配置EVdPdNd L3VdPdNdv4 over SRv6 BE网络切片相关的知识，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。在PE1和PE2之间通过建立双向SRv6 BE承载EVPN L3VPNv4业务。此外，为了满足保障CE1和CE2之间VPN实例vpn1的业务SLA，可以在公网上创建网络切片20，专门承载vpn1的业务；为了满足保障CE3和CE4之间VPN实例vpn2的业务SLA，可以在公网上创建网络切片30，专门承载vpn2的业务。
图1 配置EVPN L3VPNv4 over SRv6 BE网络切片组网图
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PE1、P和PE2上创建网络切片实例，并指定基础接口和创建网络切片接口。
-
在PE设备上配置IPv4 L3VPN实例并将IPv4 L3VPN实例绑定到接入侧接口。
-
在PE和CE之间建立EBGP对等体关系。
-
在PE设备之间建立BGP EVPN对等体关系。
- 在PE设备上配置SRv6 BE。配置IS-IS的SRv6能力。
-
在PE1和PE2上配置Route-Policy，为VPN实例路由染色。
-
配置SRv6 BE路由颜色（Color）与Slice ID的映射关系。
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的配置过程与PE1类似，不再赘述，详情可参考配置文件。
