Is this so, and are there any specific documents I should review about the performance of FreeBSD routing? As I haven't used FreeBSD before (I've been using Debian for about 10 years), I am wanting to make sure my expectations are not unreasonable. I've discovered that there is the 4.11 release and the 5.4 release. Are there any compelling reasons why I should choose one of these over the other, for my intended application? The only application I will be running is quagga. I'm planning to connect the FreeBSD server to a trunk port on a Cisco 2950 and put each interconnected IP provider into a separate VLAN. The documentation I've read so far suggests that FreeBSD is happy with VLANs - will this arrangement work and will it have any significant effect on performance?
