Re: Mikrotik Cloud Core Router and BGP real life experiences?

["Nick Olsen" <nick () flhsi com>]

Exactly what Faisal Said. The BGP process appears to be single threaded at 
the moment. So taking on full BGP tables can be a bit slow compared to a 
decent X86 box. But in terms of raw forwarding power they are pretty 
monstrous.

We replaced a few Maxxwave 6 port Atom's with the CCR. ~400Mb/s and ~40K 
pps aggregate across all ports. CPU load went from ~25% to ~0-2%. These are 
in a configuration where they have little or no firewall/nat/queue rules. 
And in most cases are running MPLS.

We've not had any issues with stability so far either (Knock on wood).

FYI... Mikrotik Cloud Core routers are nice, however one has to keep 
something in mind when deploying them...

Only One Core (of the CPU) is dedicated to each port / process.
So this is good so as  to contain what happens on a single port from taxing 
the whole CPU..
But not so good when you need more cpu power than a single core for that 
port.

Also, BGP process will only use one core.

While these units make for great 'customer facing' edge routers, with 
plenty of power and the ability to keep issues contained... The X-86 based 
(Core2Duo/i5/i7) Mikrotik are more suitable (Processing power wise) for 
running multiple full BGP tables peering.

Regards & Good Luck.
