OpenBGPD/OpenBSD: Free OpenBSD-based EGP/IGP routing platform. Solid, secure, free, and very scalable. Again, you're operating without vendor support. Non-standard of BGP functionality (modeled after PF). Awesome integration with CARP and PF, makes for great firewalls, routers and route servers. If you are system administrator and appreciate Unix, you will fall in love with OpenBGPD. If you are a Linux admin, you will be surprised at the lack of learning curve involved. Community support is actually pretty good.
The 'traditional' vendors sell the fact that you are wrapped in the warmth of their support, but remember how difficult it can be to have a TAC department support a BGP implementation that is complex (and one it doesn't see every day).
My point is that the reality of support should be based on their ability to deal with product/firmware-specific issues (which hopefully can be dealt with off-crisis by the existence of redundancy), and the client should rely on other sources for configuration/implementation support. So if you don't want to pay for product/firmware support, and you can handle your own configuration/implementation support (meaning you are good at both system administration and BGP operations), the free and semi-free (read Imagestream and OpenBGPD) options are great choices, and have made many organizations happy, despite the scare tactics of the larger vendors.
ich hatte auch nen story gelesen wo die das fuer nen isp das bandbreiten magement komplet gemacht haben aber die find ich auf die schnelle nicht
