Bidirectional Forwarding Detection on Link Aggregation Group Interfaces
RFC 7130, “Bidirectional Forwarding Detection on Link Aggregation Group Interfaces”, is a Proposed Standard document published in February 2014 by M. Bhatia, M. Chen, S. Boutros, M. Binderberger, J. Haas. The canonical text is published by the RFC Editor.
Abstract
This document defines a mechanism to run Bidirectional Forwarding Detection (BFD) on Link Aggregation Group (LAG) interfaces. It does so by running an independent Asynchronous mode BFD session on every LAG member link.
This mechanism allows the verification of member link continuity, either in combination with, or in absence of, Link Aggregation Control Protocol (LACP). It provides a shorter detection time than what LACP offers. The continuity check can also cover elements of Layer 3 (L3) bidirectional forwarding.
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.
