Extended Message Support for BGP
RFC 8654, “Extended Message Support for BGP”, is a Proposed Standard document published in October 2019 by R. Bush, K. Patel, D. Ward. It updates RFC 4271. The canonical text is published by the RFC Editor.
Abstract
The BGP specification (RFC 4271) mandates a maximum BGP message size of 4,096 octets. As BGP is extended to support new Address Family Identifiers (AFIs), Subsequent AFIs (SAFIs), and other features, there is a need to extend the maximum message size beyond 4,096 octets. This document updates the BGP specification by extending the maximum message size from 4,096 octets to 65,535 octets for all messages except for OPEN and KEEPALIVE messages.
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.
