The failure modes as defined by the original protocol standards are based on a number of assumptions around the impact of session failure. Numerous incidents both in the global Internet routing table and within Service Provider networks have been caused by strict handling of a single invalid UPDATE message causing large-scale failures in one or more Autonomous Systems. This memo describes the current use of BGP-4 within Service Provider networks, and outlines a set of requirements for further work to enhance the mechanisms available to a BGP-4 implementation when erroneous data is detected. Whilst this document does not provide specification of any standard, it is intended as an overview of a set of enhancements to BGP-4 to improve the protocol's robustness to suit its current deployment.}, }
