We have been noticing a strange issue in CCR-1036. PPPoE connections are getting dropped frequently and reconnect in the time span of 1-2 minutes. In same Mikrotik there are other PPPoE connections on same interface with uptime more than 20 hrs without any issue. We have checked L2 connectivity thoroughly and could not find any issue. After reading other posts, disabled encryption in PPPoE server and disabled MPLS package but still no luck.
RouterOS 6.33.1
Firmware 3.27
Connectivity from user to Mikrotik is stable. 0% packet loss.
