RSVP-TE Extensions for Associated Bidirectional Label Switched Paths
RFC 7551, “RSVP-TE Extensions for Associated Bidirectional Label Switched Paths”, is a Proposed Standard document published in May 2015 by F. Zhang, R. Jing, R. Gandhi. It has since been updated by RFC 8537. The canonical text is published by the RFC Editor.
Abstract
This document describes Resource Reservation Protocol (RSVP) extensions to bind two point-to-point unidirectional Label Switched Paths (LSPs) into an associated bidirectional LSP. The association is achieved by defining new Association Types for use in ASSOCIATION and in Extended ASSOCIATION Objects. One of these types enables independent provisioning of the associated bidirectional LSPs on both sides, while the other enables single-sided provisioning. The REVERSE_LSP Object is also defined to enable a single endpoint to trigger creation of the reverse LSP and to specify parameters of the reverse LSP in the single-sided provisioning case.
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.
