OSPF-Based Layer 1 VPN Auto-Discovery
RFC 5252, “OSPF-Based Layer 1 VPN Auto-Discovery”, is a Proposed Standard document published in July 2008 by I. Bryskin, L. Berger. The canonical text is published by the RFC Editor.
Abstract
This document defines an Open Shortest Path First (OSPF) based Layer 1 Virtual Private Network (L1VPN) auto-discovery mechanism. This mechanism enables provider edge (PE) devices using OSPF to dynamically learn about the existence of each other, and attributes of configured customer edge (CE) links and their associations with L1VPNs. This document builds on the L1VPN framework and requirements and provides a L1VPN basic mode auto-discovery mechanism. [STANDARDS-TRACK]
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.
