I have a strange issue after update to RouterOs version > 6.41
We have a Wisp network of 30 routers that works with pppoe over vpls tunnel, over mpls ospf routing.
At the edge we have ebgp with CCR1036.
In the network we have RB1100AHx2 and RB2011.
The isue is that on the RB2011 we have problem of strange packet loss over the clients, that affects voip and gaming. We think about packet loss and try and try and try a lot of troubleshooting.
We change for example all the values of MTU on the various devices but without success. The problem ends if you change the RB2011 with a CCR or a RB1100AHx2.
Have anyone idea of why?
Thanks a lot!
