The last two months we have enjoyed articles about routing in IP fabrics, including a new routing protocol, Routing in Fat Trees (RIFT). In this final chapter of the series, the authors from Arrcus provide us with an overview of a new protocol designed to simplify the building and operation of large-scale data centers. Enter Link State Vector Routing (LSVR) protocol, an emerging protocol developed by the IETF for hyperscale data center and cloud providers which augments BGP by replacing its path vector algorithm with a Shortest Path Dijkstra algorithm. The main advantages of LSVR include but not limited to view of complete fabric topology, faster convergence compared with classic BGP and operation simplicity. The CTN editors hope that you enjoy reading this series, please let us know if you have any questions or comments.
