RADIA PERLMAN is a Fellow at Intel Labs, working on the design of various network routing and security protocols. She is the inventor of the Spanning Tree Algorithm, the designer of IS-IS, and the original concept for TRILL. She is the author of the textbook Interconnections: Bridges, Routers, Switches, and Internetworking Protocols. She is an IEEE Fellow and holds a Ph.D. from MIT.

DONALD EASTLAKE 3rd is Co-Chair of the IETF TRILL Working Group and a voting member of IEEE 802.1. He is the author of 56 IETF RFCs and a Principal Engineer with Huawei Technologies working on advanced network product research. Previously, he was a Principal Engineer at Cisco Systems and before that a Distinguished Member of Technical Staff at Motorola Laboratories, working on network protocols, security, and mesh networking.

    I am just a novice in the field of Networking. The way the document is suggesting (or talking about the merger of Layer-2 and Layer-3, OSI perspective) what will be a future for the person who would like to start thinking about Routing & Switching career, such as Cisco’s CCIE?

    This is because what I have perceived from the concept of RBridge is that a new a device, indeed it is, with the features of Layer-2 (framing) and Layer-3 (routing) being merged, and if these devices replace the existing switches (the newer one i.e. L2 and L3) with the RBrigdge WHAT WILL HAPPEN TO A ROUTING AND SWITCHING ENGINEER?
