This was indeed user error. All I needed was local.address=172.16.204.2 in the BGP config to get it working. By default without it set it will try use the highest IP address, which was a Public IP address in my case. The RouterOS v6 to RouterOS v7 converted config certainly needs a bit of tweaking a...

Does anyone else get one CPU core constantly pegged at 95.5 - 100%?

Just put my last remaining CCR2004 on RouterOS v7.1.1 (I ripped out all of my CCR2004's about 1 year ago).

Hi, I upgraded one of my PROD CCR2004's (arm64) last night to RouterOS v7.1.1 and I can't get a simple iBGP peering established with my CCR1036 RouterOS v6 Router. This PROD CCR2004 is along my redundant path so no traffic should be passing through it. It is very possible that it is user error by me...

One of our 2004s was sent to Mikrotik (at their request through a SUP). We opened the ticket back in July. The RMA was approved in August and the 2004 was boxed and shipped to Baltic Networks for return to Mikrotik in early September. Last week (March), it was shipped back to me. The box was never ...

Very simple configuration-
Only two static routes, some mangle rules and a few firewall rules.

For your sake I hope the issues I have experienced are caused due to running x2 Full BGP tables. If I was you I would be planning for it to experience lockups/reboots.

I had another lockup after changing from a OSPF/BGP to Static Routes/BGP Network Design. CCR1036-8G-2S+'s have been ordered and I will be swapping out all of my CCR2004's ASAP. In my opinion Mikrotik should stop selling CCR2004's until ROSv7 is up to scratch and has confirmed resolved these issues. ...

Just swapped some 2004s for 1072. That is sad you had to resort to replacing the CCR2004's. Do you have any plan for returning them and getting your money back or anything along those lines? Starting to feel like having stable 2004s require routeros 7 Yes I am starting to get that feeling as well. ...

Are you using 1Gs - optics or rj45?

Yes, some of my cross-connects are 1000BASE-LX 1Gbps. I am pretty sure the Router <-> Router 10Gbps iBGP was going up and down on the 6.49beta11.

I tried 6.49beta11 and BGP was flapping like mad on it, certainly don't run that version in production.

I dont have lockups in ospf/bgp. We have seen interface down/ups and resets. Hmm, maybe that is what I have been experiencing too. I haven't noticed any syslogs for the interface going up/down though. The syslogs that I have noticed are "OSFPv2 neighbor x.x.x.x; state change from Full to Down....

I have just re-designed my network to be Static Routes/BGP instead of OSPF/BGP. I hope removing OSPF from our design has resolved these issues. If not I think my only option is to replace these CCR2004's. Does anyone have any thoughts on Full BGP tables being too much for the CCR2004's to handle (CP...

I had another OSPF/BGP lockup running 6.48.1, it auto recovered.

What version of RouterOS are you running? I might swap to that. This bug claims to be fixed in 6.47.8 and then some more in 6.48. Ive had reboots on 6.48 but not on 6.47.8 so running 6.47.9 now. These is also a version 6.49rc11 that fixes some more, but it broke sfp support. /Mikael @mhugo In regar...

Very interesting, It potentially could of been a lockup. I really am hoping it wasn't because that would mean I have to buy new Routers :(

@markonen what are your BGP peer uptimes? Maybe you have experienced a BGP lockup without noticing it?

I have been impacted by OSPF/BGP lockups a lot more than reboots.

Full feeds from one or two transits (over both IPv4 and IPv6, so 2-4 sessions) + some peering. So one CPU core is more or less pegged doing BGP. Thank you so much for this information @markonen My plan of attack is to downgrade to 6.47.8 with OSPF and x2 Full BGP Tables. If the OSPF/BGP lockup or r...

Ive had reboots on 6.48 but not on 6.47.8 so running 6.49.9 now. [/quote] Saying that do you think 6.47.8 is the gold standard since you haven't had any OSPF/BGP lockups or reboots on it? I am very curious to know what version @markonen is running since he hasn't suffered OSPF/BGP lockups or reboots.

CCR2004 needs RouterOS 7 to use the full 4GB of RAM. With ROS6 it can only use 1792MB. So if that has been enough for you, then the 1016 should work fine (in terms of RAM). Thank you very much for explaining that, I think you just saved me a few hundred or thousand dollars :) I saw your post on the...

I run five 2004s in production with full BGP tables (and a couple more without BGP) and they don’t suffer from the reboots. I’ve tried to pattern match the things people are reporting in this thread and OSPF stands out—I don’t run OSPF but many people reporting reboots here seem to. If you are runn...

What version of RouterOS are you running? I might swap to that.

CCR2004 - 4GB RAM CCR1016-12S-1S+ - 2GB RAM CCR1036-12G-4S - 4GB RAM CCR1036-12G-4S-EM - 8GB RAM CCR1072-1G-8S+ - 16GB RAM It looks like the CCR1016-12S-1S+ only has 2GB of RAM so I have doubts it will be able to handle x2 Full BGP Tables. System < Resources on our CCR2004 running x2 Full BGP Tables...

Hi guys, I am affected by the https://forum.mikrotik.com/viewtopic.php?t=164578 CCR2004 OSPF/BGP lockup and reboot issues. I made a post detailing my findings that is in an approval state. My number one priority is replacing our x4 CCR2004's with something else. It looks like I purchased these CCR20...

Do NOT buy CCR2004's. I have x4 CCR2004's (version 6.47.1) in production running OSFP and x2 Full BGP tables and I am experiencing these issues. Last night I experienced a full OSPF/BGP lockup where the Routers had to be manually rebooted to recover (1 hour drive to the Data Centre at god forsaken ...
