• BGP is optimised for the sort of static network that we do not have. There is a good reason why the internet requires micromanagement to the point of insanity - BGP doesn't actually give each host an accurate picture of the network. Which is fine, if you're not trying to create a city wide wireless network.... there is a neat little test case on our network _right now_ that I can use to prove this, if only I could be bothered drawing the diagram. But consider clusters that are connected to major routers at each end, rather than one single backbone connection. And of course TCP stalls are fun, since most people aren't using a wifi friendly implementation such as tcp_westwood (shame on you!). If you are into micromanagement, though, it does at least allow you to override other config choices. And if you don't, then you're , because it requires it to work _at all_.

• OSPF is a fragile , falling apart at the drop of an elephant. It theoretically works, but in reality it falls apart quicker than you can say "I thought bgp was going to save the world!". And this is ignoring the fact that area 0 has all of the downsides of BGP, with none of the good sides. OSPF implementations completely fail to interoperate without massaging, and indeed the default settings of most of them are total shite anyhow. One single dumb can destroy the entire network with a stupid config choice. This is not a theoretical attack - this has happened before. Requires less micromanagement than BGP, which is great, but doesn't provide the capability to do the management that you _do_ need to do. Word!
