I have problem with disappearing dinamic default route on SXT. It’s happening randomly, after few hours and after few days…no rule. SXT works in client (station) mode, connected via pppoe-client to AP. On various version of ROS (5.x) is same problem. Anyone with same siptoms ?!
Did you check the pppoe interface on that time? connected or disconnected?
It might be the provider problem, if you use “add default route” when ever the interface goes connected it got the default route from PPPoE server.
pppoe-client remains connected but no default route when I do MAC telnet to SXT from AP and see routes in ip route table.
Yes, add default route is checked.
