[AusNOG] Microtik bgp issues

[Beeson, Ayden]

AFAIK it can use them all, just not for BGP. Packet handling etc is all multi-core now as I understand it.

http://www.mikrotik-routeros.com/tag/multicore/ seems to have some really good stuff in the linked presentation for those interested.

Thanks,
Ayden Beeson

ROS7 is when these improvements will come. Only slight improvements making it into ROS6. ROS7 beta is hoping to be released Q1 2015 at this rate, based on info from Janis in a support ticket I had with him.

I was thinking they were delaying the CCR1072 for ROS7 release together, but Janis confirmed CCR1072 will release with ROS6 :( WHy have 72 cores if can't use them all lol.

Ahhhh, that'd explain why I have one CPU core constantly at 100% :)

Any idea how far away those enhancements are? :)

There is an AU mikrotik mailing list (http://talk.mikrotik.com.au) frequented by many mikrotik pro folks who do that kind of thing on a day to day basis.  Some of them are also consultants who can take on a project for you, plus all of the major distributors usually have engineering team available fo that sort of support contract.

One thing to watch out for, though, is that there does still exist a limitation with routerOS that allows only a single CPU core for bgp and routing table processing, so for busy routers with large bgp tables and regular updates, it is not so uncommon that one cpuy core will peg and raouting updates start to suffer.  It does need several tens (perhaps 100s) of thousands of route prefixes to show up this problem, but it sure can be a showstopper for major nodes.

Since routerOS is based on linux kernel, updates to kernel code to support multi-core enhancements will (apparently) eventually overcome that limitation ;)

Cheers!

Hi Guys,

Just wondering if anyone out there has had success with bgp on the microtik's and I can pick your brain?

I've got a CCR1009 and I'm struggling to get the BGP session established. Can telnet to 179 on my providers router and it looks like the settings I've got are correct but its failing to establish a connection...

Any suggestions?

Or anyone do any consulting on list that can give me a (paid) hand at all?
