ASPATH Loop

2009-05-10 Thread yangyang. wang
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 24

why not AS number based prefixes aggregation

2008-09-08 Thread yangyang. wang
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 aggregatin
