qxwd123:

Using LEDE Reboot 17.01.0 r3205-59508e3 on Lenovo Y1.
After setting the Inactivity timeout to something not 0 in luci (option demand '5' in the config file),the dial procedure will be stopping at some stage,can't establish a connect.
And the log will be like this:
May 7 08:48:52 OpenWrt daemon.info pppd[9714]: Plugin rp-pppoe.so loaded.
May 7 08:48:52 OpenWrt daemon.info pppd[9714]: RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5
May 7 08:48:52 OpenWrt daemon.notice pppd[9714]: pppd 2.4.5 started by root, uid 0

May 7 08:48:52 OpenWrt daemon.notice pppd[9714]: remote IP address 10.112.112.112

Without the demand option everything works fine:
May 7 09:08:43 OpenWrt daemon.info pppd[2712]: Plugin rp-pppoe.so loaded.
May 7 09:08:43 OpenWrt daemon.info pppd[2712]: RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5

(these logs is copy from the openwrt bug ticket[[https://dev.openwrt.org/ticket/13474|External Link]] because my log for this part had be override by massive "ieee80211 phy1: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2",sincere apology,smile)
It seems to be a historied legacy bug from Openwrt BB (or AA),and there is a solution by changing 2 files to make pppd disconnect when inactivity but can't re-dial:
1./etc/config/network, disable IPv6
config interface 'wan'
option ipv6 0

2./lib/netifd/proto/ppp.sh: change nodefaultroute to defaultroute in the function of ppp_generic_setup()
proto_run_command "$config" /usr/sbin/pppd
nodetach ipparam "$config"
ifname "$pppname"
${keepalive:+lcp-echo-interval $interval lcp-echo-failure ${keepalive%%[, ]*}}
${ipv6:++ipv6}
defaultroute </code>
Hope this stinking bug can be terminated in LEDE
