I've only dealt with a handful of the bigger networks, but every transit BGP session I've ever been the customer role on has been filtered by the provider. From memory and in no particular order, that's UUNet, Level3, Digex, Intermedia, Global Crossing, Genuity, Sprint, Above.net, Time Warner, C&W, MCI, XO, Broadwing, and a few smaller ones nobody's likely to have heard of.
We take transit from some of these providers, and I we have a slightly different experience. While it's not quite a free-for-all, some have implemented a limit on the number of announced prefixes without any restriction to specific space. We found this out after AboveNet dampened us for announcing too many routes. No one there could ever produce any substantial evidence of that, or provide us a single example of one of these routes - but we were told it was strictly the number of prefixes that mattered. I know that I provide newly assigned prefixes to our providers, which includes PCCW. If those make it into a prefix-list at PCCW though, I don't really know for sure. -- Ross Vandegrift ross () kallisti us "The good Christian should beware of mathematicians, and all those who make empty prophecies.
