[TL]{网络}{ppp}{讨论}有关pppoe的问题,PPPoED阶段PADI后没回应，重启以后能连上(网线直连)

[Tomt]

情况是这样：
如果pppoe断线以后， 用wireshark抓包发现只有 PPPoED(Active Discovery Initiation(PADI) )

plog:
 pppd[3019]: Plugin rp-pppoe.so loaded.
 pppd[3020]: pppd 2.4.4 started by root, uid 0
 pppd[3020]: Timeout waiting for PADO packets
 pppd[3020]: Unable to complete PPPoE Discove

但是重起以后又可以，
这个是什么原因？

这是之前做的一些尝试，
    /etc/ppp/options:
    --- lcp-echo-failure 3
    +++ lcp-echo-failure 30
    +++ maxfail 0
