Rosen}, title = {{Detecting and Reacting to Failures of the Full Mesh in IPLS and VPLS}}, pagetotal = 8, year = 2004, month = sep, day = 30, abstract = {Certain L2VPN architectures {[}IPLS, VPLS{]} rely on there being a full mesh of pseudowires {[}PWE3-ARCH{]} among a set of entities. This mesh is used to provide a 'LAN-like' service among the entities. If one or more of these pseudowires is absent, so that there is not really a full mesh, various higher layers (from routing to bridge control protocols) that expect a LAN-like service may fail to work as expected. Therefore it is desirable to have procedures that enable the pseudowire endpoints to determine automatically whether there is really a full mesh or not. It is also desirable to have procedures that cause the L2VPNs to adapt to pseudowire failures. This document proposes a set of procedures to meet these goals. Detailed protocol encodings are not present, but will be added in future versions.}, }
