IS-IS Extensions Supporting IEEE 802.1aq Shortest Path Bridging
RFC 6329, “IS-IS Extensions Supporting IEEE 802.1aq Shortest Path Bridging”, is a Proposed Standard document published in April 2012 by D. Fedyk, P. Ashwood-Smith, D. Allan, A. Bragg, P. Unbehagen. The canonical text is published by the RFC Editor.
Abstract
802.1aq Shortest Path Bridging (SPB) has been standardized by the IEEE as the next step in the evolution of the various spanning tree and registration protocols. 802.1aq allows for true shortest path forwarding in a mesh Ethernet network context utilizing multiple equal cost paths. This permits it to support much larger Layer 2 topologies, with faster convergence, and vastly improved use of the mesh topology. Combined with this is single point provisioning for logical connectivity membership, which includes point-to-point, point-to-multipoint, and multipoint-to-multipoint variations. This memo documents the IS-IS changes required to support this IEEE protocol and provides some context and examples. [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.
