Quagga

Carlos Renato Tasinafo · External Since: Jul 04, 2007 Posts: 2

Hello All,

I'd like to known if anyone here uses Quagga (BGP daemon particularly)
in large-scale ( 6 neighbours - full routing )
I'm worried about the performance of the system. Anyone have any
experience?
Thanks in advance

Regards
Carlos Renato Tasinafo

Thank you so much Jogi,
I'm not sure about the performance, because I had a bad experience with
Cisco 3640 . When I activated the full routing mode in this router,
the bgp connection was reset apparently because lack of memory. One
and half years ago the routing table received (full) was approximately
160k , Today I think this number is above 220 k.
Best regards,

Carlos Renato Tasinafo.

You shouldn't worry too much about quagga performance (quagga's CPU
usage won't be a limiting factor, the main limit will be how fast
your machine can forward packets), and one of the main advantages of
using quagga is that memory for your typical Linux system is a LOT
cheaper than Cisco's.

For your reference: I just checked one of our routers, the "zebra"
process is using 50 MB, and "bgpd" is using about 100. We receive two
feeds of about 220k routes. So for the current size of the routing
table I'd guess you need at least 350 MB of memory (6x 50 MB for
bgpd, and 50 for zebra).

Regards,

Maarten

We are using quagga as core router.
Only one BGP neighbor, and currently using Dual Xeon and 4G of ECC RAM.
First of all, try to use intel NIC card rather than other brand, because
intel NIC card could handle more packet than others like realtek.
secondly, I would suggest you put 1-2G RAM to your router, because you
WILL use other things on router such as SNMP daemon to monitor bandwidth,
CPU usage, memory usage...etc which also take up memory.

points to an article about a pair of Mac Minis running Quagga tied in to
a pair of gigabit switches.
They say they are moving about 42mbit of traffic, no statement on the
size of their routing table though.
