Rbridge Mailing list

An rbridge is a hybrid router/bridge designed to provide bridge-like layer-2 connectivity with better layer-2 forwarding than current spanning tree bridges. This list provides a venue for discussing and developing the rbridge. The concept is outlined in the following paper:

Perlman, Radia, "Rbridges: Transparent Routing," Proc. Infocom 2004, Mar. 2004. Click here for a cached copy of the PDF.

Slides from Radia's talk are available in PowerPoint and PDF.

Additional information:

Virtual Internet Architecture: The rbridge can be described as a layer-2 network within a virtual router, and as such is an instance of a recursive virtual router described in the Virtual Internet Architecture:

J. Touch, Y. Wang, L. Eggert, G. Finn, "Virtual Internet Architecture," Future Developments of Network Architectures (FDNA) at Sigcomm, August 2003. Available as ISI-TR-2003-570.

Fred Templin's Templin-IPVLX is a system using ipv6 for addressing and ipv4 for encapsulation over rbridge-like devices; it discusses a number of related issues as a result.
