🔒70% of BGP Paths Have Modified ORIGIN Attributes
Most Internet Routes Are Lying About Their Origin
TL;DR
A new study finds that nearly 70% of Border Gateway Protocol (BGP) routes have their origin attribute modified. This could affect how traffic is routed and perceived across the internet.
New research reveals that approximately 70% of BGP paths have their ORIGIN attributes altered, contrary to established standards. This manipulation can influence route selection and network traffic patterns. The study highlights a significant divergence between intended routing practices and actual implementations, impacting the reliability of global internet infrastructure. Key findings include: 89.8% of routes are marked as IGP (Internal Gateway Protocol), while 3.5% are EGP (External Gateway Protocol) and 6.7% are INCOMPLETE.
Key Points
70% of observed BGP paths have an ORIGIN value different from the originating AS
89.8% of routes marked as IGP, 3.5% EGP, 6.7% INCOMPLETE
ORIGIN attribute should not be modified by routers after initial set
Manipulation can influence route selection and traffic patterns
Study analyzed updates from RIPE RIS and RouteViews public collectors
Why It Matters
Network operators must now account for ORIGIN manipulation when assessing route integrity. This impacts how ASes manage their networks, especially in terms of traffic diversion and security.
