21 号刚好我碰到重拨了，发现的时候看到是光猫重启了，更换的 7005tv3 。在爱快里面进行多拨设置，被断开后，爱快拨号失败，提示 lcp:timeout sending config-request 。更换 mac 即可重拨成功。
光猫 2.5 口直接连的爱快硬路由。爱快默认拨号会自己成功，混合 vlan 模式必须改 mac ，怀疑是不是默认 pppoe 是随机 mac 的

@djdifndk 2000m 的哥们可以加一下交流交流？

我最近重拨的比较厉害，朝阳区 2000m

@alpha9318 咨询了营业厅，正式发售后，只要有人办就会升级小区域的设备，现在的 10gpon 肯定不行

@cpxjaz 老哥你的 2000m 换猫后重拨的厉害吗？

@spacezip 你也是 2000m 吗。1000m 没任何问题

有木有联通 2000m 交流下呀，近期准备升万兆

@trepwq 桥接后测速上行 200 多，下行上不去不知道为啥

移动的光宽带现在还能开吗？

@zzz2021zzz 都可以

@bella0727 感谢，那估计差不多都是这样的。动态公网好像坚持不了几天就重拨了

@wcloudme 都开了的，就很神奇，这个 KVM 机器 ping 外界时 tcpdump 没有反应，但是当从外界 ping 进来居然有反应，但是 ping 网关和其它同个内网的 ip 都是不通的。
