Title : Operational Requirements for Enhanced Error Handling Behaviour in BGP-4
Author(s) : R. Shakir
Filename : draft-ietf-grow-ops-reqs-for-bgp-error-handling-00.txt
Pages : 22

BGP-4 is utilised as a key intra- and inter-Autonomous System routing
protocol in modern IP networks. 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.
