I have been using FreeBSD 8.0 and as well 7.2 but from a routing perspective i would say you could go ahead with 8.0 for the reason being 7.2 still does not support ECMP but 8.0 supports ECMP which is quite important but having said that load balancing and fast protection has got issues in 8.0 too but from a longer run 8.0 would be better choice as Qing and other few people are putting lot of fixes to flowtable and general routing infrastructure . Hope this helps Thanks, Cheers, - Balaji On 4/22/10, Paul Thornton wrote: > > Hi list, > > A bit of advice please, folks. > > We currently use 6.2-release + Quagga as a router on a number of boxes. > These are stable but we have seen some CPU issues recently and clearly the > code is all getting old now, and so I'm starting to look at updating them. > > Specifically, the hardware consists of a single dual-core Xeon at 2GHz with > 2G RAM, containing 10x em interfaces (2x quad PCI-X cards, plus 2 onboard) . > IRQ sharing is a bit of an issue and only 8 of those 1G ports can be used > without re-using an interrupt. > They run with polling enabled, with kern.polling.user_frac = 22 > These routers run Quagga 0.99.7 doing v4 and v6 OSPF/BGP. > We do use a number of vlans and a couple of gif tunnels. > Total throughput varies quite a lot - from 50M to about 200M - but usually > isn't high. > > There seem to be a lot of issues that have appeared around 8.0 and the em > code, and although patches have quickly appeared, I know that a lot of the > forwarding and routing code in 8 is new - so whilst I would normally have > just tested this with 8 and not considered anything else, I am thinking that > maybe sticking with 7 is a better plan. > > I'd appreciate any input from anyone who is using 8.0 in a similar > environment, any advice and suggestions would be gratefully received. > > Thanks, > > Paul. > > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" >
