Hi,
Running the “Bugfix Only” software stream - currently 6.40.8 - on model 2011iL, as my firewall/router on a UK FTTC line with Andrews & Arnold (TalkTalk wholesale last mile). Using the BT OpenReach supplied FTTC modem as the WAN side.
Problem: If the FTTC line blips (or I simulate a blip by pulling out the FTTC cable for a few seconds), the PPPoE session does not restart unless the Watchdog option is enabled.
With watchdog feature enabled, the line comes back up every time, but of course it takes around 90 seconds because the whole RouterOS machine has to reboot.
Is there anything I can change in my config to make the FTTC PPPoE link recover automatically without relying on the watchdog? Config attached
Many thanks
Martin

Hello,
/interface pppoe-client
add add-default-route=yes default-route-distance=0 disabled=no interface=eth1_WAN keepalive-timeout=disabled max-mru=1500 max-mtu=1500 name=pppoe-out1 password=xxx profile=aaisp user=xxx
Your problem is that keepalive-timeout is disabled. Set this to what is usually the default of 10 (seconds) and you shouldn’t have this problem.
I use the same setup on both my plusnet, my mothers BT and some 2000+ clients using pppoe and nobody has to reboot to regain ppp sessions.
Thanks Steve, much better now!
Just for testing, I set 5 seconds at my end, and 10 seconds at the ISP end. Now recovers quickly if I pull the modem ethernet cable out for 5 to 15 seconds.
Annoyingly, if instead I pull the BT modem phone cable out for a few seconds, it still takes around 40 seconds to recover (though this is still quick enough to avoid the watchdog kicking in and rebooting RouterOS.) I wonder if all FTTC modems take a similar amount of time to negotiate a link?
Cheers
Martin
Did you set up the PPPoE client with WebFig? I did this too and assumed that it would set the keepalive timeout to the default but it doesn’t, it sets it to disabled. Very annoying!
