mlag 配完后，流量只走单边，成员口一个没选中，大神们，解释哈么

type1配置是否保持一致呢。05-DRNI配置-新华三集团-H3C

您好，请知：

检查下M-LAG的配置看下有没有问题。

以下是配置案例，请参考：

.22  DRNI典型配置举例

1.22.1  DRNI基本功能配置举例

1. 组网需求

·     由于用户对于业务的可靠性要求很高，如果Device C和接入设备（Device A和Device B）之间配置链路聚合只能保证链路级的可靠性，接入设备发生故障时则会导致业务中断。这时用户可以采用DRNI技术，正常工作时链路进行负载分担且任何一台设备故障对业务均没有影响，保证业务的高可靠性。

·     配置三层以太网接口为保留接口，在该三层以太网口上搭建Keepalive链路，保证Keepalive报文能够正常传输。
