Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

we got 4 new crs317 as replacement (they have been tested at our supplier) but they show the same behaviour.... the recommended crs309 and 312 do not work as a replacement for us since we need the port density in that specific usecase. Has anyone given the new MikroTik CRS326-24S+2Q+RM a try? in an ...

Re: Ring of switches and Vlans

I think I am having the same issue. I have 2 CRS317 and 2 CRS328 connected in a ring. one of the 328 sees 1 interface as root port and one as alternate port - so everything works as expected but it throws those loop warnings in the log exactly once a minute. also I have connected 2 ccr1009 to those ...

Re: ospf losing route

It looks like the problem dissapeared after setting the type of the interface from "broadcast" to "point2point". However i am not sure if that is really a solution. I do not fully understand what broadcast vs. point2point has to do with this particular issue.

Re: OVPN client certificate checking

Thanks for your answer.

is there any reason for not checking server certificate? even with client certificates enabled this opens the door for some attack vectors. To me this is rather disappointing.
Thanks anyway for the SSTP alternative recommendation.
