Using CCR 1036-12G-4S [v6.39.2]
There’s two of my CCRs where the PPPoE connections are dropping at random intervals. I’m checking if there is some issues with MTU, MRU. Both are set on “1492”.
Using pppoe debug, I cannot find out if the MTU/MRU are reaching the limit: Actually, Is kinda a difficult understand this.

Sniffing one of interfaces that PPPoE connections dropped. Using the terminal to extract and copy the information, it doesn’t show what the interface winbox says:
Example: Protocol 34916 (pppoe-session) - Size = 1502.. (bellow is the information from terminal)

Anyone has ideas for help to debug this problem?
