ASPATH Loop
Hi, NANOG: When I was analyzing the BGP RIB data from RouteViews, I found that there were aspath loop in many bgp rib entries. For example, in the file rib.wide.20090301.0319, the peer 202.249.2.169 in AS2497 observed the following aspaths: 3130 29283 3130 2914 2497 3130 7337 3130 2914 2497 3130 34486 3130 2914 2497 3130 38001 3130 2914 2497 3130 13977 3130 2914 2497 3130 25147 3130 2914 2497 3130 5433 3130 2914 2497 3130 26164 3130 2914 2497 3130 34026 3130 2914 2497 3130 31535 3130 2914 2497 3130 14363 3130 2914 2497 3130 29648 3130 2914 2497 3130 27582 3130 2914 2497 3130 39737 3130 2914 2497 3130 33796 3130 2914 2497 3130 15108 3130 2914 2497 3130 9600 3130 2914 2497 .. As we know, BGP instance running on routers don't allow loop in ASPATH, why they can be seen in RIBs? It's some particular technical configuration in practice? OR What's wrong with AS3130?? Thanks Yangyang
why not AS number based prefixes aggregation
Hi, everyone: For routing scalability issues, I have a question: why not deploy AS number based routing scheme? BGP is path vector protocol and the shortest paths are calculated based on traversed AS numbers. The prefixes in the same AS almost have the same AS_PATH associated, and aggregating prefixes according to AS will shrink BGP routing table significantly. I don't know what comments the ISPs make on this kind of routing scheme. -yang
Re: looking for help for the statistics data on spoofing attack events on Internet
Dear Mr. Morrow: Thank you! We have already found CAIDA's backscatter, MIT's spoofer project. Spoofer project focuses on how much space in the Internet could be spoofable. It is very helpful for our experiment. But we also want to know how often the spoofing events(such spoofing IP attacks, spoofing route update) occurs, or the degree of their activity in real world. Monitoring the Internet widely is very difficult,so I hope to get some useful infomation by surveying the related statistical data and report from organization. currently, this way has no effective result. 2007/12/24, Christopher Morrow [EMAIL PROTECTED]: On Dec 24, 2007 12:08 AM, yangyang. wang [EMAIL PROTECTED] wrote: We are conducting an experiment to evaluate IP source address spoofing attacks on Internet and want to collect some statistics data or report about it Which organization or research group could support some statistics data, report or hints on the spoofed IP source address attack events, DNS spoofing events, router forged update events on the whole Internet or regional network for research analysis? you might get some mileage from the spoofer-project out of MIT: http://spoofer.csail.mit.edu/ have fun!
