2、文档假设您已了解NQA和VRRP特性。3配置举例3.1组网需求如图1所示，Host主机需要访问Router C，Host的缺省网关为172.32.20.1/24；Router A和Router B属于虚拟IP地址为172.32.20.99/24的备份组11；当Router A正常工作时，Host发送给Router C的报文通过Router A转发；当Router A出现故障时，Host发送给Router C的报文通过Router B转发。图1VRRP与NQA联动典型配置举例3.2配置思路为使能NQA，创建track项关联NQA和VRRP；为使RouterB作为备份，设置备份组的IP需与Rout

3、erA上的一致，且优先级较低。为使能PPPOE，配置RouterA上的PPPOE server和Router C上的PPPOE Client功能。3.3使用版本本举例是在Release 2207P14版本上进行配置和验证的。3.4配置注意事项在配置VRRP监视Track项之前，需要先在接口上创建备份组并配置虚拟IP地址。不允许对IP地址拥有者进行监视指定Track项的配置。被监视Track项的状态由Negative变为Positive后，对应的路由器优先级会自动恢复。被监视的Track项可以是未创建的Track项。可以通过vrrp vrid track命令指定监视的Track项后，再通过tra
