The IESG has received a request from the Operational Security Capabilities for IP Network Infrastructure WG (opsec) to consider the following document: - 'BGP operations and security' <draft-ietf-opsec-bgp-security-05.txt> as Best Current Practice The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-09-22. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract BGP (Border Gateway Protocol) is the protocol almost exclusively used in the Internet to exchange routing information between network domains. Due to this central nature, it is important to understand the security measures that can and should be deployed to prevent accidental or intentional routing disturbances. This document describes measures to protect the BGP sessions itself (like TTL, TCP-AO, control plane filtering) and to better control the flow of routing information, using prefix filtering and automatization of prefix filters, max-prefix filtering, AS path filtering, route flap dampening and BGP community scrubbing. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-opsec-bgp-security/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-opsec-bgp-security/ballot/ No IPR declarations have been submitted directly on this I-D.
