1.  Introduction

   The Interface to the Routing System (I2RS)
   [I-D.ietf-i2rs-architecture] provides read and write access to the
   information and state within the routing process that exists inside
   the routing elements, this is achieved via the 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 Routing Information Base (RIB).
   [I-D.ietf-i2rs-usecase-reqs-summary] introduces a set of RIB use
   cases and the RIB information model is defined in
   [I-D.ietf-i2rs-rib-info-model].
