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]
This document is a product of the IS-IS for IP Internets Working Group of the
IETF.
This is now a Proposed Standard Protocol.
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 Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol. Distribution of this memo is unlimited.
