1.  Introduction

   The Interface to the Routing System (I2RS) provides read and write
   access to the information and state within the routing process within
   routing elements via protocol message exchange between an I2RS Client
   and an I2RS Agent associated with the a routing system.  The
   [I-D.ietf-i2rs-architecture] describes the basic interactions of this
   exchange.  One of the important functions of this messages exchange
   is for the I2RS client to interact with one or more I2RS agents to
   collect information from network routing systems.

   One of the key information pieces that I2RS clients may collect from
   I2RS agents is the BGP information regarding BGP peers, BGP routes,
   and network topologies created within BGP.  This document introduces
   a basic information model for BGP policies.  This policy model can be
   linked with other information models such as the I2RS RIB
   informational model [I-D.ietf-i2rs-rib-info-model], and uses the
   generic policy found in the Policy Routing modules in
   [I-D.hares-i2rs-info-model-policy].  This basic BGP Information Model
   is an extendable policy model is a product of the industry approach
   to I2RS.

3.1.2.  Elements in I2RS Protocol Block

   This section describes each element of the I2RS Protocol Block.

   Router-ID (R)

      This I2RS BGP IM element stores the ROUTER-ID which is configured
      in the BGP protocol as the default router-id.  Instances of a
      protocol may configure unique router-IDs.  The router-ID is a 32
      bit unsigned value imported from the running BGP process.

   Router-ID (W)

      Upon a write from the I2RS Client to this I2RS BGP IM element,
      this I2RS Agent will temporarily change this default in the BGP
      protocol.  I2RS Agent-routing system software must be able to
      handle both the original value (from node configuration systems),
      and the I2RS value as valid defaults.  This change in the ROUTER_-
      ID default is passed to the BGP instances spawned from the BGP

      protocol.  After the I2RS Client stops the relationship with the
      I2RS Agent, the Router-ID value reverts to the configured value.

   AS(R/W)

      This I2RS BGP IM element stores the default AS number configured
      in the BGP implementation.  This value is 8 byte value represented
      as a decimal value.  This value is a read-write value.  The
      initial value of the AS is imported by the I2RS Agent from the BGP
      protocol in the BGP routing system.  This the normal case.  If
      this data element is written to, I2RS stores the default AS number
      value in the BGP protocol as the new default AS in the BGP
      protocol.  This does not change the default AS number in existing
      BGP instances with the existing peers.  New BGP instances spawned
      after the I2RS changes the default AS value, should have the I2RS
      specified default AS.  Upon the completion of the I2RS client-I2RS
      Agent association, the default AS value should be returned to the
      configured value.

   protocol_status (R)

      This I2RS BGP IM element stores an administrative status for the
      protocol activity of "no-shutdown" (0x00) or "shutdown" (0x01).
      If the routing entity the I2RS protocol is attached has BGP
      "shutdown", no data will be available from any BGP instances.
      This is a read-only variable.

   shutdown_protocol(R/W)

      A write of "TRUE" to the "shutdown_protocol" status in the I2RS
      Agent indicates the I2RS agent should request a shutdown of the
      BGP protocol from the routing function.  The default value is
      "FALSE" for this I2RS variable.  The read of the
      "shutdown_protocol" indicate the current status of the
      "shutdown_protocol" variable in the I2RS Agent.  This is different
      than the "protocol_status" which indicates the status of the
      protocol: shutdown or not "shutdown" (running).

   bgp_role (R)

      The BGP_ROLE provides a list of BGP Roles found within the BGP
      Instances associated with the BGP protocol function on the device
      associated with the I2RS agent.  These can be ASBR (AS border
      router E-BGP), PE (Provider Edge E-BGP), IBGP peer, or RR (Route
      Reflector).

   bgp-ipv4-uni-instance (R-W)

3.2.  bgp_ipv4_instance

   BGP protocol support within a router(or virtual routing device) may
   have multiple instances of the BGP protocol.  This section describes
   the information regarding the BGP protocol available to the I2RS
   Agent.  The section begins with a top-level diagram of the Yang Data
   Model, and then goes to define the Yang data model in text.

3.2.1.  Yang Data Model bgp ipv4 unicast instance

   This figure below the yang model at bgp instance to handle the bgp
   instance.  Within Yang, the definition is based on a a grouping which
   has name, I2rs creation flags, standard instance type, vendor type,
   afi, safi, bgp local RIB, and BGP peers.  The standard instances
   types are: IPv4 unicast, IPv4 multicast, IPv4 L3vpn, VPLS, MDT, EVPN,
   BGP-ls, IPv4-mpls-vpn, IPv4-mpls-mvpn, BGP route-targets, IPv4 flow,

      The bgp-local-rib contains the contains a local RIB for BGP
      associated with this BGP instance.  Every BGP instance has its own
      local RIB which contains the routes received by all Peers (Adj-
      RIB-IN per Peer), and selected by policy as the active route by
      the local BGP speaker's Decision Process.

   bgp-peer-list (R/W)

      contains a list of BGP Peer information (BGP_PEER) associated with
      this BGP instance.  A write to this BGP Peer list adds a BGP Peer
      to this BGP instance.

   rib-in (R/W)

      This contains bgp-rib-in route list.

   rib-out (R/W)

      This contains bgp-rib-out route list.

3.3.  bgp local rib

   The routes associated with each BGP instance are the BGP local RIB,
   the AdjRIBIn, and the AdjRIBOut.  The BGP local RIB is described
   below.  The AdjRIBIn is the bgp_rib_in described in the BGP_Peer
   section.  The policy that sets preferences on the routes received by
   the peer is identified by the Peer_policy_in (an policy set name),
   and fully readable by the Peer_policy_in_pset (policy set pointer)
   entry.

   The AdjRIBOut is contained in bgp_rib_out (a route list) described in
   the BGP Peer Section.  The Policy associated with the AdjRIBOut is
   identified by the Peer_policy_out (a policy set name) and fully
   readable by the Peer_policy_out_pset (policy set pointer).

   This section describes the bgp local ribs for IPv4 unicast routes as
   a prototype for all rib routes.

   Each bgp local RIB listed below may be created and stored as a prefix
   tree.  However, yang model descriptions describe it as a list of
   routes with an index of prefix and length.  The above top-level yang
   demonstrates this.  This yang mechanism requires a unique definition
   per AFI/SAFI.

   Each rib is indexed by the prefix/prefix-length and contains route
   type, attribute list, route creation information, and state
   information.  The IPv4 local RIB shows the full definition of the

3.4.2.  Elements in BGP peer Structure

   The following are the elements in the BGP_Peer structure

   BGP_PEER_NAME (R/W)

      This entry uniquely names a BGP Peer.  If multiple TCP connections
      are utilized between two BGP Peers, then the BGP Peer uniquely
      identifies the Peering.  An I2RS Write to a BGP_PEER_NAME changes
      the BGP_PEER_NAME For the duration of the I2RS client-agent
      association for the run-time BGP, but it does not change the
      configured BGP Peer name.

   Peer_Session_Address (R/W)

      provides local peer address information and remote peer address
      information.  Please see the description below for the details of
      the BGP session address.  An I2RS read of this information pulls
      this information pulls up the the BGP Peer data in ephemeral
      store.  The I2RS write to this causes the peer to attempt to set-
      up a TCP session either initial TCP session or a second TCP
      session in with multiple TCP support

   BGP_PEER_TYPE (R/W)

      contains the status on the type of BGP such as EBGP, IBGP, RR, RR-
      Client, PE, or CE. or Vendor specific types.  (I2RS Note: Does
      this match normal configuration expectation or should this be an
      I2RS special variable)

   BGP_Peer_create(R/W)

      provides the I2RS creation status for this peer as: not-created by
      I2RS, requested by client but not processed, or an I2RS agent's
      response to the request: (agent reject peer creation, agent
      attempting peer creation, Agent failed peer creation, and Agent
      created BGP Peer).

   Peer_policy_in (R/W)

      - This allows reference of the bgp inbound policy by policy set
      name.  Policy sets are defined by [RFC3460], and refers to the
      name of the policy set.  This allows I2RS to read/write the policy
      set name, and let the I2RS agent link in the appropriate policy
      set.

   Peer_policy_out (R/W)

      - This allows reference of the outbound policy by policy set
      names, and let the I2RS agent load an existing policy set.

   Peer_policy_in_pset (R/W)

      Full policy set loaded for Peer_policy_in_pset.

   Peer_policy_in_pset (R/W)

      Full policy set loaded for Peer_policy_in_pset.

   Peer state info (ro)

      includes the following information:

      *  Peer_current_state (R) the the current state of the BGP Peer in
         the BGP state machine.

      *  Peer_last_state (R)

      *  Peer_down_reason (R) which includes the reason and the sub-
         error codes for bgp header errors, bgp open errors, bgp update
         errors, and bgp route refresh errors

      *  peer-received-update-cnt (ro) - received

      *  peer-transmit-update-cnt (ro)

      *  peer-received-route-cnt (ro)

3.4.3.  Reading/Writing Policy in I2RS IM model for BGP Peer

   The I2RS Agent's peer inbound and outbound policies are logically
   considered to be stored in policy sets that logically are defined in
   [RFC3460] but have the additions to be appropriate for I2RS basic
   network policy as described [I-D.hares-i2rs-bnp-info-model].  Policy
   groups uniquely identified by a Policy name.  Policy sets are
   described either by name so that an on-board policy set is associated
   with the I2RS control BGP peer, or by full policy sets (-pset).  This
   section describes why the choice to allow both name for pre-loaded
   policy sets and full policy set description.

   Some I2RS clients will have long-term connections to I2RS Agents
   associated with a BGP routing function, and may choose to transfer
   the BGP Policy set or a set of the BGP Policy Components to the
   client's local memory.  In this case, the I2RS Client could request
   the I2RS Agent to simply transfer the BGP Policy Sets name used by
   for the BGP Peers to minimize travel along with an indication of the
   last time the policy was updated.

   The policy variables Peer_policy_in and Peer_policy_out allow both
   read and write of the Policy set names.  The read of the
   Peer_policy_in and Peer_policy_out will provide simply the policy-set
   name.  The write of the Peer_policy_in the I2RS agent will need to
   valid the the policy set name.  After the policy set name is
   validated, the policy set link is placed in Peer_policy_in_pset and
   the BGP routing function updated with the policy set lists for the
   BGP Peer.

   Similarly, if a write occurs to I2RS Agent's Peer_policy_out, the
   I2RS agent validates the policy-set name , replaces
   Peer_policy_out_pset with the link to the policy-set identified by
   the Policy-set name.

   Reading either Peer_policy_in_pset will result in the I2RS Agent
   passing the policy linked to by the Peer_policy_in name (and linked
   to by Peer_policy_in_pset) to the I2RS Client in policy set form.
   Similarly, reading the Peer_policy_out_pset will retrieve the policy
   set pointed to by the Peer_policy_out name, and transfer the data in
   policy set form.
