   7 :abbr:`SHARP (Super Happy Advanced Routing Process)` is a daemon that provides
   8 miscellaneous functionality used for testing FRR and creating proof-of-concept
   9 labs.

  13 Starting SHARP
  14 ==============
  15
  16 Default configuration file for *sharpd* is :file:`sharpd.conf`.  The typical
  17 location of :file:`sharpd.conf` is |INSTALL_PREFIX_ETC|/sharpd.conf.
  18
  19 If the user is using integrated config, then :file:`sharpd.conf` need not be
  20 present and the :file:`frr.conf` is read instead.
  21
  22 .. program:: sharpd
  23
  24 :abbr:`SHARP` supports all the common FRR daemon start options which are
  25 documented elsewhere.

  29 Using SHARP
  30 ===========
  31
  32 All sharp commands are under the enable node and preceeded by the ``sharp``
  33 keyword. At present, no sharp commands will be preserved in the config.
  34
  35 .. index:: sharp install
  36 .. clicmd:: sharp install routes A.B.C.D <nexthop <E.F.G.H|X:X::X:X>|nexthop-group NAME> (1-1000000) [instance (0-255)] [repeat (2-1000)]
  37
  38    Install up to 1,000,000 (one million) /32 routes starting at ``A.B.C.D``
  39    with specified nexthop ``E.F.G.H`` or ``X:X::X:X``. The nexthop is
  40    a ``NEXTHOP_TYPE_IPV4`` or ``NEXTHOP_TYPE_IPV6`` and must be reachable
  41    to be installed into the kernel. Alternatively a nexthop-group NAME
  42    can be specified and used as the nexthops.  The routes are installed into
  43    zebra as ``ZEBRA_ROUTE_SHARP`` and can be used as part of a normal route
  44    redistribution. Route installation time is noted in the debug
  45    log. When zebra successfully installs a route into the kernel and SHARP
  46    receives success notifications for all routes this is logged as well.
  47    Instance (0-255) if specified causes the routes to be installed in a different
  48    instance. If repeat is used then we will install/uninstall the routes the
  49    number of times specified.
  50
  51 .. index:: sharp remove
  52 .. clicmd:: sharp remove routes A.B.C.D (1-1000000)
  53
  54    Remove up to 1,000,000 (one million) /32 routes starting at ``A.B.C.D``. The
  55    routes are removed from zebra. Route deletion start is noted in the debug
  56    log and when all routes have been successfully deleted the debug log will be
  57    updated with this information as well.
  58
  59 .. index:: sharp label
  60 .. clicmd:: sharp label <ipv4|ipv6> vrf NAME label (0-1000000)
  61
  62    Install a label into the kernel that causes the specified vrf NAME table to
  63    be used for pop and forward operations when the specified label is seen.
  64
  65 .. index:: sharp watch
  66 .. clicmd:: sharp watch nexthop <A.B.C.D|X:X::X:X>
  67
  68    Instruct zebra to monitor and notify sharp when the specified nexthop is
  69    changed. The notification from zebra is written into the debug log.
