A first step towards checking BGP routes in the dataplane
Thomas Wirtgen, Olivier Bonaventure · 2022
BGP is a fragile routing protocol since it is based on an implicit system of trust between the Autonomous Systems (AS) participating in the exchange of routes on the Internet. Any router can announce the routes it wants without being the owner. Due to the lack of a validation system for the announcements made by BGP routers, a series of RFCs published after the release of BGP have partially solved this problem by introducing the Resource Public Key Infrastructure (RPKI).
