This document defines a specialized, dynamic routing protocol for
Clos, fat tree, and variants thereof. These topologies were initially
used within crossbar interconnects and consequently router and switch
backplanes, but their characteristics make them ideal for
constructing IP fabrics as well. The protocol specified by this
document is optimized towards the minimization of control plane state
to support very large substrates as well as the minimization of
configuration and operational complexity to allow for a simplified
deployment of said topologies.
This document is a product of the Routing In Fat Trees Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
