From my (operational) experience:
CPU load to import a full table from ground zero, on router hardware: 100% "" "" "" "" , on server hardware: <2% Main problem with using server hardware (and I am not talking about a Linux box on a Taiwanese manufacturer, here; I'm talking hardware considered by the majority of successful businesses to be stable enough to support their core applications): Lack of stable and useable routing software. Zebra: OSPF is twitchy, BGP is either great or takes > 1 hour to converge a full table, with no clear reason why, and it does not support anything but Linux/Intel sanely, yet. GateD public: No reflector code. End of story. GateD private: Segfaults & other fun games, unresponsive support, closed code. MRTD: (As far as I can tell) requires injection of full routing table into kernel routes for base OS, no sane way to turn this off, support for non-BGP protocols is spotty at best. Anyone able to significantly disprove one of the above, or provide another package that does not have the problems, would have my deep and abiding gratitude, because this issue is rather active in my current work-life. -- *************************************************************************** Joel Baker System Administrator - lightbearer.com lucifer@lightbearer.com http://users.lightbearer.com/lucifer/

Maybe im just lucky but the only problems ive had with zebra so far is with equal cost multipath. Everything else works great. -Dan -- [-] Omae no subete no kichi wa ore no mono da. [-]

On Linux/Intel, it works fairly well. On Solaris/Sparc, it does well to compile. At all. Much less run. Much less run stably. -- *************************************************************************** Joel Baker System Administrator - lightbearer.com lucifer@lightbearer.com http://users.lightbearer.com/lucifer/

I'm running Zebra on a Netra AC-200 (Solaris 8) with 256MB RAM with a couple BGP peers. Zebra doesn't claim to support Solaris but it works fine. I'll give you that it's slow and don't do anything in Solaris that will show you the routing table (either 'sh bgp ro' or 'netstat -nr') - Solaris seems to have an issue displaying 110k routes. - mz
mrtd has been out of development for quite a while now, actually. But iirc, you could disable injection of routes via the -n flag. -j

No real problems on OpenBSD/i386. Very nice with Tyan Thunder KT7 based boards. Looking forward to the current round of peer-group code going in. You want commercially supported BGP, but Cisco/Juniper/whatever. You want free - use the source, Luke. Peter

Like for every other free software system, there are probably companies which do commercial support for Zebra. And, if nobody does it yet, my company will probably start doing it soon :-) Last minute: there is at least one company doing so. See <http://www.zebra.org/faq.html>.

Never seen that.
with no clear reason why, and it does not support anything but Linux/Intel sanely, yet.
I use Zebra only on Linux/Intel, so it does not bother me. But I know personnally several people who run it happily on FreeBSD/Intel and the Zebra mailing list clearly show that most Zebraers seem to prefer *BSD to run it.
