Prioritized Treatment of Specific OSPF Version 2 Packets and Congestion Avoidance
RFC 4222, “Prioritized Treatment of Specific OSPF Version 2 Packets and Congestion Avoidance”, is a Best Current Practice document published in October 2005 by G. Choudhury. It has since been updated by RFC 9454. The canonical text is published by the RFC Editor.
Abstract
This document recommends methods that are intended to improve the scalability and stability of large networks using Open Shortest Path First (OSPF) Version 2 protocol. The methods include processing OSPF Hellos and Link State Advertisement (LSA) Acknowledgments at a higher priority compared to other OSPF packets, and other congestion avoidance procedures. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
