DRNI是一种跨设备链路聚合技术，将两台物理设备在聚合层面虚拟成一台设备来实现跨设备链路聚合，从而提供设备级冗余保护和流量负载分担。
组网需求
如图1所示，Device A和Device B为接入设备，Device C和Device D为网关设备。现要求使用DRNI技术实现接入设备的冗余保护和流量负载分担功能。具体要求如下：
· 在Device A和Device B上部署DRNI，实现接入设备的冗余备份和流量负载分担。
· 分别在Device A和Device B上配置保留接口，用于DRNI主备设备间Keepalive报文的传输，检测Device A和Device B是否故障。
· 在Device C和Device D上部署VRRP，当网关设备工作正常时，区域A用户通过网关设备Device C进行数据转发；区域B用户通过网关设备Device D进行数据转发，实现流量的负载分担。
· 当Device C或者Device C的上行接口发生故障后，Device D能够迅速承担区域A内主机流量的转发任务；Device C故障恢复后，继续承担VRRP备份组1的网关功能。
· 当Device D或者Device D的上行接口发生故障后，Device C能够迅速承担区域B内主机流量的转发任务；Device D故障恢复后，继续承担VRRP备份组2的网关功能。
· 在Device C、Device D和Device E上搭建OSPF网络，Device C和Device D通过OSPF发布区域A和区域B内的主机所在网段的路由，以实现区域A和区域B内的主机与外部网络的三层互通。
