1.  Introduction

   The Interface to the Routing System (I2RS) [RFC7921] provides read
   and write access to the information and state within the routing
   process that exists inside the routing elements, this is achieved via
   protocol message exchange between I2RS clients and I2RS agents
   associated with the routing system.  One of the functions of I2RS is
   to read and write data of the Routing Information Base (RIB).
