Just another subtle reminder that prefix-filtering (@ access and inter-provider -- at least well-known address space) could have a significant impact -- if/when this does occur.
Whilst I have no quarrel with the excellent positions espoused by the likes of Paul Ferguson et al. about ingress filtering of transit customers, or for that matter similar positions on ingress prefix-filtering of BGP customers, I wonder why it is that there is not more support amongst the transit ISP fraternity for the use of route-servers for implementing prefix- filtering. All I hear is, "But the routers aren't up to full prefix-filtering; AS-path based filtering (if that) is the best we can hope for" etc. What were route-servers invented for if it wasn't for implementing routing policy, and leaving core routers to the job of advertising and accepting prefixes according to local policy, and IP packet forwarding? Yes, I realise there are resiliancy issues to be considered here... M.
