Detecting Inactive Neighbors over OSPF Demand Circuits
RFC 3883, “Detecting Inactive Neighbors over OSPF Demand Circuits”, is a Proposed Standard document published in October 2004 by S. Rao, A. Zinin, A. Roy. It updates RFC 1793. The canonical text is published by the RFC Editor.
Abstract
OSPF is a link-state intra-domain routing protocol used in IP networks. OSPF behavior over demand circuits (DC) is optimized in RFC 1793 to minimize the amount of overhead traffic. A part of the OSPF demand circuit extensions is the Hello suppression mechanism. This technique allows a demand circuit to go down when no interesting traffic is going through the link. However, it also introduces a problem, where it becomes impossible to detect an OSPF-inactive neighbor over such a link. This memo introduces a new mechanism called "neighbor probing" to address the above problem. [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.
