It eats up a lot of CPU, so once you hit a certain number of BGP peers, it may start intermittently flapping BGP sessions, or even justcrash the bgpd process entirely.For what numbers? I've two quaggas, ~150 peers each, doing as-path and *full* prefix filtering for each peer (Config is around 9MB). CPU is idle 99.x% mostly ...
Yea, but not 150 full feeds. With some full feeds flapping Quagga has a hard time. This is mostly due to poor scheduling of its poor internal multithred scheduler. Fortunatly the root cause has been identified and fixes are currently being discussed on the Quagga lists. Nontheless I prefer OpenBGPd because its internal design is made for many full feeds and it's parts run asynchonously from each other. The only missing thing there is full filtering capabilities which are under development currently. And of course that I pay the time for one of the OpenBGPd developers employed at my company. ;-) If you want to tip the jar too you are most welcome. -- Andre [Oppermann] [aka andre () FreeBSD ORG] ( http://www.networx.ch )
