Re: BGP ECMP (multipathing)

as a workaround, ECMP works perfectly with OSPF instead of BGP, assuming your setup allows for it. alternatively, the tip provided by heribertos using routing filters forcing the "Next-Hop-in" to your desired multipath gateways might work, though you'll lose the fully dynamic aspect of BGP by essent...

Re: How to Copy dynamic Route to another route table

i've required this feature several times already. i understand i could use a route reflector to give all my routes back to me and put then with a different routing mark, but that would require a separate router with extra physical connections, which makes no sense as it should be very easy to do a c...

Don't know if it's already been mentioned, but I can no longer change the name of a user in /user
It's not only the default user, it applies even to newly created users.

Re: CCR 0.3%+ packet loss whenever above 5% CPU

Do you have connection tracking turned on? how big is your connection tracking table? I found previously that port scanning created many connections to port 445 filling up connection tracking table and causing CPU spikes. Not sure if this is exposed to the Internet or not and whether you are blocki...

Re: CCR 0.3%+ packet loss whenever above 5% CPU

Re: CCR 0.3%+ packet loss whenever above 5% CPU

OK.. also, good idea to check for certain bad settings that can kill your performance, for instance turning on "Use IP firewall" in the bridge settings kills the CPU, good to identify whether there might be some issue like that.
Good one.
In my case it was already disabled in all routers.

Re: CCR 0.3%+ packet loss whenever above 5% CPU

OK.. also BTW I think you misunderstand fastpath - fastpath is automatically active when it is enabled and you have no firewall rules. Fasttrack is kindof a 'fastpath-lite' where you can fastpath some traffic in situations where you need to have firewall rules and other such things. It is not as ef...

Re: CCR 0.3%+ packet loss whenever above 5% CPU

Can you paste your config with the hide sensitive option? What did you learn from the profiler? You should be able to see when a CPU is maxed what process is maxing out that CPU. I need to update RouterOS, the current version in that CCR doesn't support per-core profiling. Will do that later tonigh...

Hello.

CCR 0.3%+ packet loss whenever above 5% CPU

We have several CCRs and noticed small levels of packet loss (anywhere from 0.3% upwards of 2%) whenever CPU utilization is above 5%. One thing we noticed is the only scenario the packet loss doesn't happen is when the CCR is using Fast Path for all its traffic. If Fast Path is disabled (firewall ru...

Re: Queue priority of IPs within network

Thanks!

I didn't test it under load but the queues at least seem to be working.
Another question, is it possible to only limit the /32 host at 25 Mb/s if the /24 network is under full load but if it's using 0 Mb/s let the /32 host use as much as he wants, up to the 100 Mb/s?
