问题描述
RBM切换测试中主设备DOWN掉上行接口后，主设备vrrp状态切换为Initialize状态，备设备仍然保持Backup状态不进行切换。
过程分析
1、组网：标准组网，主备设备上行口均为1/0/1
2、主设备DOWN掉1/0/1接口后vrrp变化：
===============display vrrp verbose===============
IPv4 Virtual Router Information:
Running mode : Standard
RBM control channel is established
VRRP active group status : Master
VRRP standby group status: Master
Total number of virtual routers : 9

此时备设备vrrp状态：
===============display vrrp verbose===============

3、故障时主设备隧道情况查看如下，且测试两端HA通道互通：

4、此时注意到现场组网，现场配置了多组RBM+VRRP，检查备机其他组VRRP状态是异常的，其他组备机VRRP状态异常相当于备机的状态是异常的。
解决方法
现场配置了多组VRRP+RBM，一组VRRP状态异常的话会影响整个设备的RBM状态，检查时需要检查所有VRRP组状态。现场这组VRRP状态异常的原因是因为未接网线，接好网线后切换测试恢复正常。
