About 10% of direct peers and 6 of 16 Tier-1 ASes manipulate ORIGIN, with rewriting ASes heavily concentrated at the top of the AS hierarchy. This manipulation allows transit providers to attract more traffic and revenue by making their routes appear more preferred in BGP path selection. The post argues that since ORIGIN manipulation is widespread, technically unjustified, and creates unfair competition, the attribute should be deprecated or made irrelevant in route selection, and calls for renewed IETF discussion on the topic. ## Full article daily.dev links to this article rather than hosting it.
