Hello,

I have a question cuz i truly dont fiind any answears for it.

I whant to buy an CCR1036-8G-2S+EM and use it in ower DC with 2 providers, BGP, at the moment we use Vyos installed on a server with 8GB Ram and an six core Cpu.

We have global table with more then 1.6m routes

BGP router identifier xxxx, local AS number 33xxx vrf-id 0
BGP table version 1942037
RIB entries 1491080, using 262 MiB of memory
Peers 5, using 102 KiB of memory



At the moment on ower vyos router the cpu usage is 0.1 nothink, and ram is 3GB

My question is dose CCR1036-8G-2S+EM will handle 1.6m routes/tables or how you guys call it ?

I`m not an expert , i do this (bgps,…etc) since January :slight_smile: before wa was colocated on an DC.

Thank you.

Problem with ccr is slow single core performance. With BGP one cpu is 100% all the time. You will see slow routing table updates. I see seldom watchdog reboots causing a big network interuption. MT is working on this but it may take a long time until this is stable. Forwarding performance is fine as this is done on more cores.
I consider going VMware with CHR or vyos.

Thank you, i was not expecting this to be onest, the think is i whant to get rid of vyos cuz it has bugs the bgp it get stoped by snmp since version 1.2 and not even till now they didnt fixed

So we should give vmware/CHR a try. Using an adequate CPU single core performance should improve by a big number.

For BGP performance choose CCR2004 or CHR

CCR10xx is slow on single-core performance as needed by BGP.

There are a lot reports of instabilities with ccr2004 on this forum …

Hello,

First i was thinking to buy this CCR1036-8G-2S+EM and use it for 1 year and after to upgrade to CCR1072-1G-8S+ but :slight_smile: like i see here they die with full tables there is no worth to buy them, i dont whant to use only the metro tables (1.6k routes) it works even with an ubiquity 300$ 1GB Ram :)) so where is the point for

CCR1036-8G-2S+EM or CCR1072-1G-8S+ if they ar not working with the full tables ?! Oka yea because of the big traffic and not bgp but when you start to have like 2-3gb traffic 24/24 you go to buy a cisco 100k $ :slight_smile: not 2-3k $ router

1036 EM can run a couple of bgp feeds just fine, but as written above convergence is slower.

2004s are much faster but we have issues with reboots despite mikrotik claiming it should be fixed. Right now between every 14 and 35 days.

Forget MikroTik for BGP with full routes.
It doesn’t matter which model you use. Or even CHR.

It is simply not usable when dealing with more than a 200-300k routes.

It’s not only terribly bad at convergence times, but even a simple prefix search can take 10-15 minutes and in the meantime the whole BGP process freaks out and peers start to timeout one after the other.

It’s just terrible. Avoid it at all costs if you wanna sleep good at night.

Stay on x86

In my experience stay of Vyos is more stable and super fast on installing routes when you have BGP Flapping. To have the same performance on mikrotik you should wait for RouterOS V.7 to be in production!
