华为运营商级路由器配置示例 | EVdPdNd VPLS over SRv6 BE（CE双归接入）
2024-06-04 06:57:11
组网需求
如图1所示，CE2和CE3同时双归接入到PE2和PE3。要求CE1发往CE2的流量采用负载分担方式进行传输，而CE1发往CE3的流量采用非负载分担方式进行传输。
为了实现上述需求，可以基于ESI粒度设置冗余模式，即，配置CE2接入PE的冗余模式为多活跃模式，配置CE3接入PE的冗余模式设置为单活跃模式。
图1 配置EVPN VPLS over SRv6 BE（CE双归接入）组网图
配置思路
- 使能PE各接口的IPv6转发能力，配置各接口的IPv6地址。
- 在各PE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
- 在PE设备之间建立BGP EVPN对等体关系。
- 在PE设备上配置SRv6 BE。
- 在PE设备上配置将相应的BD绑定到接入侧子接口。
- 在PE上配置基于ESI粒度设置冗余模式。
- 配置CE接入PE。
操作步骤
1.使能各接口的IPv6转发能力，配置IPv6地址

[*PE1-LoopBack1] quit
[*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。这里以PE1为例，其他设备的配置过程相同，详情可参考配置文件。
2.配置IS-IS

[*PE3-LoopBack1] commit
[~PE3-LoopBack1] quit配置完成后，可以执行display isis peer和display isis route命令检查IS-IS是否配置成功。以PE1为例：

GigabitEthernet3/0/0 Up 1 从显示信息可以看出，对于Eth-Trunk 10，PE2和PE3是双主状态；对于Eth-Trunk 20，PE2处于备状态，PE3处于主状态。
9.检查配置结果
在PE上通过配置命令display bgp evpn all routing-table，可以看到远端发来的EVPN路由。以PE1为例：
