Hi all, I'm thinking to use a Mikrotik router as a border router in a peering point, two router-server send something like 50K prefixes each,
and one peer send ~100K prefixes, few send ~20K-30K, the rest 100 or less prefixes.
In the end the router will receive near ~200K-300K prefixes in this peering point, and is it possible to reduce the numbers filtering low prefixes like /23,/24...
I was reading that the Mikrotik on the bgp process are quite slow and using filters the result is one core of the cpu is always 100% used.
I was reading the post about the RB4011 vs CCR1009, and initially the RB4011 can be an interesting choice but it have 1GB of ram so the limit can be reached
quite easily if the peering point grow in members/prefixes.
Someone have real and concrete experience using a Mikrotik as border router in situation like this ?
I heard about some providers that use a Mikrotik in AMSIX or DECIX...fairy tale ?
and in the case of receiving one or two full route from the uplinks, night dreams ?

I appreciate every useful answer, because I'm tring find out if the Mikrotik can be more other than a cheap CPE where I'm working.

Hi there,

The CCR1009-7G-1C-1S+ is (in my opinion) an excellent router to use for BGP. I have one in a Sydney AU datacentre and it loads a full BGP feed (about ~750,000 routes) in less than 2 minutes. They are quite flexible, however the only downside is the fact that it's only got 1 x 10Gb port (I've always thought MT should release a CCR1009-8G-2S+)...

Cheers,

Can You tell me some stats about this router? Like the memory usage and process load? Are You using filters on the full route ?

(I've always thought MT should release a CCR1009-8G-2S+)...

There is the CCR1036 8G 2S+ if your after more, or even the 1072-8S+, or what we've done is breakout using a CRS317-1G-16S+

Hi there,

The CCR1009-7G-1C-1S+ has the below specs and features:

• 1 x 10G SFP+ cage
• 1 x 1G Combo SFP cage / Ethernet Port (caveat is that you can only use either the SFP or Ethernet port, not both)
• 7 x 1G Ethernet Ports
• Tilera 9-core CPU (TLR4-00980) 1.2GHz
• 2GB RAM

I have used them in the past, and have seen them load a full table (~750,000 routes) in under 90 seconds. It's quite a hardy and durable router. The only downside is that it only has 1 SFP+ port. If you wanted two, you could look at the CCR1036-8G-2S+ which is a little beefier:

• 2 x 10G SFP+ cages
• 8 x 1G Ethernet Ports
• Tilera 36-core CPU (TLR4-03680) 1.2GHz
• 4GB RAM

It costs about an extra $300 to $500, depending on where you are sourcing it from. Either one of those should definitely be able to handle what you want to do.

Hi there,
...

Thanks christopherh, and thanks to all for the answer, after some try&buy, I chose the CCR1036-8G-2S+ an now is running in production without any problem.
The double sfp+ port and the 4GB are points that extend the planned service for quite a lot.
Just for reference, in the lab it received a double full route from two router in 120 secs...and now in the peering point it work with 300K prefixes without sweat!

Hello!! I think that you should think at the forwarding traffic too, a CCR1009 can handle easily like 4Gbps of traffic if you disable the connection tracking and configure this router as an edge router only, which means BGP / OSPF (probably as the IGP) and that's it, it works really nice!! I've played with a CCR1009 in combination of a CRS317 with excellent results; but.. when the router is forwarding lot of traffic then the BGP convergence can be slow at some time, if you want the best of both worlds, I'll go with a CHR (check this link: https://mum.mikrotik.com/presentations/ ... 562405.pdf

Personally, I prefer a bigger router as edge (probably a CCR1036-8G-2S+ or a CCR1072-1G-8S+, because the traffic can grow easily without doing any upgrade in hardware, and you'll just need to care about your wan circuit, I've passed like 30Gbps in a CCR1072-1G-8S+ with a 40% of CPU between several interfaces.
