[Xorp-users] Problem using xorp on real internet ...

[Benjamin Sonntag]

Hi,

I'm Benjamin Sonntag, from Gitoyen.net, a french  network operator (I
made an up-to-date package for xorp on debian)

We are currently using quagga, but we have some problems with it (eg bgp
flapping during transit disconnection)

We are testing xorp and we hope we will be able to use it in production,
but a (quite huge) problem appeared during our tests :

We put our tests notes & results here (maybe in french, sorry)
https://wiki.gitoyen.net/xorp/

our second test is when xorp receive all the Internet routes from a bgp
transit operator (called bsd1 here). There is about 200K routes.

The configuration used is here :
https://wiki.gitoyen.net/xorp/config2.deb1.boot
and the bgp peer is an openbgpd whose config is here
https://wiki.gitoyen.net/xorp/config2.bsd1.boot

The point is that XORP took about 35 minutes (on this mono-xeon box) to
compute and add the routes to the fib ! During this time, xorp_bgpd and
other processes took all the cpu cycles.

Is this behavior normal ? Is Xorp bound to be used by network operator
using bgp or does it need some (big) optimizations ?

Is it something that can be done to make this far more lightweight ? or
should we use openbgpd instead for this kind of usage ?

Thanks in advance for you advices,

Best regards,

Benjamin Sonntag
