+<database name="ovn-ic-sb" title="OVN Interconnection Southbound Database">
+  <p>
+    This database holds configuration and state for interconnecting different
+    OVN deployments.  The content of the database is populated and used by the
+    <code>ovn-ic</code> program in each OVN deployment, and not supposed to be
+    directly used by CMS or end user.
+  </p>
+
+  <p>
+    The OVN Interconnection Southbound database is shared by
+    <code>ovn-ic</code> program in each OVN deployment.  It contains
+    interconnection information from all related OVN deployments, and is used
+    as the intermediate store for each OVN deployment to exchange the
+    information.  The <code>ovn-ic</code> program in each deployment is
+    responsible for syncing the data between this database and the its own
+    northbound and southbound databases.
+  </p>
+
+  <h2>Database Structure</h2>
+
+  <p>
+    The OVN Interconnection Southbound database contains classes of data with
+    different properties, as described in the sections below.
+  </p>
+
+  <h3>Availability Zone Specific Information</h3>
+
+  <p>
+    These tables contain objects that are availability zone specific.  Each object
+    is owned and populated by one availability zone, and read by other availability
+    zones.
+  </p>
+
+  <p>
+    The <ref table="Availability_Zone"/>, <ref table="Gateway"/>, <ref
+    table="Encap"/> and <ref table="Port_Binding"/> tables are the availability
+    zone specific tables.
+  </p>
+
+  <h3>Global Information</h3>
+
+  <p>
+    The data that does not belong to any specific availability zone but is
+    common for all availability zones.
+  </p>
+
+  <p>
+    The <ref table="Datapath_Binding"/> table contains the common datapath
+    binding information.
+  </p>
+
+  <h3>Common Columns</h3>
+  <p>
+    Each of the tables in this database contains a special column, named
+    <code>external_ids</code>.  This column has the same form and purpose each
+    place it appears.
+  </p>
+
+  <dl>
+    <dt><code>external_ids</code>: map of string-string pairs</dt>
+    <dd>
+      Key-value pairs for use by <code>ovn-ic</code>.
+    </dd>
+  </dl>

+    <h1>Name</h1>
+    <p>ovn-ic-sbctl -- Open Virtual Network interconnection southbound db management utility</p>
+
+    <h1>Synopsis</h1>
+    <p><code>ovn-ic-sbctl</code> [<var>options</var>] <var>command</var> [<var>arg</var>...]</p>
+
+    <h1>Description</h1>
+    <p>This utility can be used to manage the OVN interconnection southbound database.</p>
+
+    <h1>General Commands</h1>
+
+    <dl>
+      <dt><code>init</code></dt>
+      <dd>
+        Initializes the database, if it is empty.  If the database has already
+        been initialized, this command has no effect.
+      </dd>
+
+      <dt><code>show [<var>availability_zone</var>]</code></dt>
+      <dd>
+        Prints a brief overview of the database contents.  If
+        <var>availability_zone</var> is provided, only records related to that
+        availability zone are shown.
+      </dd>
+    </dl>
+
+    <h1>Database Commands</h1>
+    <p>These commands query and modify the contents of <code>ovsdb</code> tables.
+    They are a slight abstraction of the <code>ovsdb</code> interface and
+    as such they operate at a lower level than other <code>ovn-ic-sbctl</code> commands.</p>
+    <p><var>Identifying Tables, Records, and Columns</var></p>
+    <p>Each of these commands has a <var>table</var> parameter to identify a table
+    within the database.  Many of them also take a <var>record</var> parameter
+    that identifies a particular record within a table.  The <var>record</var>
+    parameter may be the UUID for a record, which may be abbreviated to its
+    first 4 (or more) hex digits, as long as that is unique.  Many tables offer
+    additional ways to identify records.  Some commands also take
+    <var>column</var> parameters that identify a particular field within the
+    records in a table.</p>
+
+    <p>
+      For a list of tables and their columns, see <code>ovn-ic-sb</code>(5) or
+      see the table listing from the <code>--help</code> option.
+    </p>
+
+    <p>
+      Record names must be specified in full and with correct capitalization,
+      except that UUIDs may be abbreviated to their first 4 (or more) hex
+      digits, as long as that is unique within the table.  Names of tables and
+      columns are not case-sensitive, and <code>-</code> and <code>_</code> are
+      treated interchangeably.  Unique abbreviations of table and column names
+      are acceptable, e.g. <code>g</code> or <code>gatew</code> is sufficient
+      to identify the <code>Gateway</code> table.
+    </p>

+      <dt><code>get-connection</code></dt>
+      <dd>
+      Prints the configured connection(s).
+      </dd>

+      Prints the SSL configuration.
+      </dd>

+      The OVSDB database remote to contact.  If the <env>OVN_IC_SB_DB</env>
+      environment variable is set, its value is used as the default.
+      Otherwise, the default is <code>unix:@RUNDIR@/ovn_ic_sb_db.sock</code>, but this

+      By default, or with <code>--leader-only</code>, when the database server
+      is a clustered database, <code>ovn-ic-sbctl</code> will avoid servers other
+      than the cluster leader.  This ensures that any data that
+      <code>ovn-ic-sbctl</code> reads and reports is up-to-date.  With
+      <code>--no-leader-only</code>, <code>ovn-ic-sbctl</code> will use any server
+      in the cluster, which means that for read-only transactions it can report
+      and act on stale data (transactions that modify the database are always
+      serialized even with <code>--no-leader-only</code>).  Refer to
+      <code>Understanding Cluster Consistency</code> in <code>ovsdb</code>(7)
+      for more information.
