BGPn
BGPn is a proposed extension to the Border Gateway Protocol (BGP) designed to address key limitations in inter-domain routing, including slow convergence, growth in routing table size, and vulnerabilities to misconfigurations and prefix hijacks. It seeks to maintain backward compatibility with existing BGP while introducing optional enhancements for incremental updates and stronger route validation.
Development of BGPn emerges from research and operator experimentation with inter-domain routing to improve efficiency and
Core ideas include support for incremental and bounded updates rather than full advertisements, optional cryptographic signing
Architecturally, BGPn would run as a layered extension atop BGP-4, with a compatibility layer that ignores unknown
Potential benefits include faster convergence, improved security through route validation, reduced routing churn, and greater resilience
