[AusNOG] Microtik bgp issues

[James Hodgkinson]

From what I’ve seen they’ve been working on it for a while but multithreaded anything can be hard to make stable :)

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?
