R22.8.8固件PPPOE踢下线重拨号后获取IPV6失败导致断网

[sarabear]

PPPOE拨号每2天会踢下线，R68S重拨号后会大概率（超过50%）获取IPV6失败导致整体都断网了，重拨号日志如下（屏蔽了部分ip和mac信息）：
除8.8固件外，曾经试过7.22和7.23其实也一样，重拨号后超过50%的概率会获取IPV6失败导致断网的。
之前一直用6.15的固件运行1个月，重拨号超过15次未出现过这个情况

一般遇到这个问题就是重启R68S就好，也能再次获取IPV6

[sarabear]

这个现在怀疑了LAN口的使用内置IPV6和DHCPV6配置了服务器通告引起的，现在把这2个都禁了，WAN里面的使用内置IPV6也禁了。还能继续分配到v6地址的，再观察一段时间看看
