Abstract

   This document defines a yang data model for a Filter-based Routing
   Information Base (RIB) Yang data model.  A routing system uses the
   Filter-based RIB to program FIB entries that process incoming packets
   by matching on multiple fields (n-tuple) within the packet and then
   performing a specified action on it.  The FB-RIB can also specify an
   action to forward the packet according to the FIB entries programmed
   using the RIBs of its routing instance.

1.  Introduction

   This document provides a yang module for flow filter n-tuple policy
   that is locally configured.  This flow filter policy has also been
   called Policy routing in some implementations.

   This document defines a yang data model for a Filter-based Routing
   Information Base (RIB) Yang data model.  A routing system uses the
   Filter-based RIB to program FIB entries that process incoming packets
   by matching on multiple fields within the packet and then performing
   a specified action on it.  The FB-RIB can also specify an action to
   forward the packet according to the FIB entries programmed using the
   RIBs of its routing instance.

1.1.  Definition of I2RS Filter Based RIB

   Filter-based routing is a technique used to make packet forwarding
   decisions based on a n-tuple filter that is matched to the incoming
   packets and the specified action.  It should be noted that that this
   is distinct from the static routes in the following RIBS:
