Edge Router Reconnect¶
Occasionally the Edge Router will loose the PPPoE connection, and won't automatically get it back.
Login via SSH and run the following:
disconnect interface pppoe0 connect interface pppoe0
Inspecting the logs can help to identify the issue.
I suspect that LCP ConfReq
lines are relevant - see the repeats before pppoe0
is disconnected in the sample output below.
show interfaces pppoe pppoe0 log
