Hello, I think this is a rather hot topic at the moment.
The Internet table keeps growing at a steady pace, more and more networks practice prefixes disaggregation, especially smaller ISPs. I do not know what are they motivation beneath, a cheap way to do traffic engineering. I saw a partner of us doing that (a /21 split into a /22 a /24 and a second /22). Everybody mentions that up to 40% of the entire table is rubbish. A lot of people around are bashing the MLs mentioning they re-aggregate these prefixes, but nobody seems to have shared their methodology, tools, algorithm or findings. I guess the hard way is to take each AS one my one and to see if they announce prefixes in weird way and if their announces can be re-aggregated, however doing this manually could take a life and would be rubbish by the end of the run. Could somebody be so good as to provide insights and some hints for those who are interested in learning how to do something barely documented anywhere? I am sure I am not the only one looking for such solution. Thanks! -- Al
