Current IEEE 802.1 LANs use spanning tree protocols that have a number
of challenges. These protocols need to strictly avoid loops, even
temporary ones, during route propagation, because of the lack of
header loop detection support. Routing tends not to take full
advantage of alternate paths, or even non-overlapping pairwise paths
(in the case of spanning trees). This document addresses these
concerns and suggests applying modern
network-layer routing protocols at the link layer. This document
assumes that solutions would not address issues of scalability beyond
that of existing IEEE 802.1 bridged links, but that a solution would
be backward compatible with 802.1, including hubs, bridges, and their
existing plug-and-play capabilities. This memo provides information
for the Internet community.
This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF.
