This document addresses the problem of the size and freshness of the endnode learning table in edge Routing Bridges (RBridges), by allowing endnodes to volunteer for endnode learning and encapsulation/decapsulation. Such an endnode is known as a "Smart Endnode". Only the attached edge RBridge can distinguish a "Smart Endnode" from a "normal endnode". The Smart Endnode uses the nickname of the attached edge RBridge, so this solution does not consume extra nicknames. The solution also enables endnodes that are Fine-Grained Label (FGL) aware.
