Revised Error Handling for BGP UPDATE Messages
RFC 7606, “Revised Error Handling for BGP UPDATE Messages”, is a Proposed Standard document published in August 2015 by E. Chen, J. Scudder, P. Mohapatra, K. Patel. It updates RFC 1997, RFC 4271, RFC 4360, RFC 4456, RFC 4760, RFC 5543, RFC 5701, RFC 6368. The canonical text is published by the RFC Editor.
Abstract
According to the base BGP specification, a BGP speaker that receives an UPDATE message containing a malformed attribute is required to reset the session over which the offending attribute was received. This behavior is undesirable because a session reset would impact not only routes with the offending attribute but also other valid routes exchanged over the session. This document partially revises the error handling for UPDATE messages and provides guidelines for the authors of documents defining new attributes. Finally, it revises the error handling procedures for a number of existing attributes.
This document updates error handling for RFCs 1997, 4271, 4360, 4456, 4760, 5543, 5701, and 6368.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
