Nathan has made a good point. Deploying them in an IX environment, with =
features like per-peer RIBs, very complex filtering, and the numbers of =
peers you might expect on a route-server environment, is a very =
different beast to (and more complicated than) deploying them in a =
network edge/forwarding role.
In a forwarding role, the underlying OS's features and the robustness of =
the daemon under load matters in different ways. =20
So what's best ? I have used all three in a forwarding role and found =
BIRD on Debian a pretty solid combination. I found OpenBGPd on OpenBSD =
a pain to use - it converged really slowly and bgpctl seemed to lock up =
for a while after startup in an environment with *many* peers, and the =
behaviour with ospf3 used to change quite a lot. Quagga on Linux or =
FreeBSD seemed to work ok, and the interface will be quite familiar to =
Cisco users.
Using all three as an injector for Anycast or similar leads to quite =
similar outcomes. However you might find ExaBGP more lightweight in =
this role - see http://bgp.exa.org.uk/ - do check it out. This has an =
interface which will feel extremely comfortable to Juniper users.
You should still go to the IX Route-Servers panel to learn more about =
the software in question :-) And its really very good research being =
presented - but I am biased here.
Best wishes
