I'm in the process of researching solutions for a new network location rollout.

We are going to have two providers one on 100mbit and 50mbit commits..

I'm wondering what linux solution i could build that could handle that much traffic.

and also how it stacks up against say a Cisco 2821 with upgraded RAM..

linux box on a decent hardware can handle traffic of few hundreds mbit/s without problems.

for bgp under linux there is not much choice - quagga.

Are people still using BIRD (bird.network.cz) ? –  Tom O'Connor Oct 8 '10 at 22:33
    
@Tom O'Connor - only production installations of bgp routing under linux that i saw were based on quagga. –  pQd Oct 9 '10 at 6:53
    
@TomO'Connor oh yes, usage of BIRD is quite heavy, take a look at this: euro-ix.net/documents/1024-Euro-IX-IXP-Report-pdf –  Marek Sebera Nov 24 '12 at 15:06

PFSense. It's FreeBSD not Linux, but if it's just a dedicated router machine, shouldn't really matter.

I wasn't aware that PFSense had BGP capability. –  Tom O'Connor Oct 8 '10 at 22:00
    
@Tom - it's available as the openbgpd package –  Mark Henderson Oct 8 '10 at 22:17
    
If you're going BSD, I would suggest using olive: juniperolive.blogspot.com/2009/02/juniper-olive.html –  Joe Oct 8 '10 at 22:19
    
Yikes, Olive looks cool but I bet it breaks all kinds of terms, conditions, maybe even laws. –  Tom O'Connor Oct 8 '10 at 22:30
    
@Joe - you have to have a copy of the Juniper OS to start with, and if you have a Juniper router, surely you'd just keep it runnong on that? –  Mark Henderson Oct 9 '10 at 4:43

I'm not sure why pQd said that there's no choice for BGP routing. Personally I heard about Zebra but never about quagga...

quagga forked [de-facto] dead code of zebra project. see: en.wikipedia.org/wiki/Quagga_%28software%29#Name –  pQd Oct 9 '10 at 19:31
