Name: draft-cheng-idr-redirection-risks-ps Revision: 03 Title: Problem statement of Inter-domain Traffic Redirection Risks Document date: 2023-07-08 Group: Individual Submission Pages: 8 URL: https://www.ietf.org/archive/id/draft-cheng-idr-redirection-risks-ps-03.txt Status: https://datatracker.ietf.org/doc/draft-cheng-idr-redirection-risks-ps/ Htmlized: https://datatracker.ietf.org/doc/html/draft-cheng-idr-redirection-risks-ps Diff: https://author-tools.ietf.org/iddiff?url2=draft-cheng-idr-redirection-risks-ps-03 Abstract: BGP Update includes the destination prefix and AS_PATH that records the AS number through which it passes. The traffic routing to the destination prefix should be forwarded along the AS sequence in AS_PATH. However, due to traffic redirection, route aggregation and etc., the AS path of forwarding and the AS_PATH of BGP Update often do not match. The inconsistency leads to security risks such as black holes, loops in inter-domain forwarding, and the possibility of forwarding through malicious AS that source/upstream AS does not want to pass through.
