WDS Dynamic mesh - loop

Thu Mar 25, 2021 10:30 pm

Hi !
I would like to ask you for help about our problem with WDS dynamic mesh. We are using mikrotik routers rb912g-5hpnd in electro vehicles moving in city. The system is sending short periodically UDP broadcast (60B/s) between connected nodes and UDP unicast 1kB/s.

Our problem is:
two times per day is system maybe in the loop and the network is flooded by ARP, UDP packets (~5000 p/s) from random nodes(sometimes old not connected nodes).

Ethernet is connected to vehicle ECU and WLAN is used only for mikrotik wds mesh. Firmware ver. is 6.48

Thank you !
There is our configuration: 
# model = 912UAG-5HPnD
# serial number = 77C9060C8947
