  14 DESCRIPTION
  15 ===========
  16 |DAEMON| is a routing manager that implements the zebra route engine. zebra supports all protocol daemons in the FRRouting suite.
  17
  18 OPTIONS
  19 =======
  20 OPTIONS available for the |DAEMON| command:
  21
  22 .. include:: common-options.rst
  23
  24 .. option:: -b, --batch
  25
  26    Runs in batch mode, zebra parses its config and exits.
  27
  28 .. option:: -k, --keep_kernel
  29
  30    On startup, don't delete self inserted routes.
  31
  32 .. option:: -s, --nl-bufsize <netlink-buffer-size>
  33
  34    Set netlink receive buffer size. There are cases where zebra daemon can't handle flood of netlink messages from kernel. If you ever see "recvmsg overrun" messages in zebra log, you are in trouble.
  35
  36    Solution is to increase receive buffer of netlink socket. Note that kernel < 2.6.14 doesn't allow increasing it over maximum value defined in /proc/sys/net/core/rmem_max. If you want to do it, you have to increase maximum before starting zebra.
  37
  38    Note that this affects Linux only.
  39
  40
  41 .. option:: -n, --vrfwnetns
  42
  43    Enable namespace VRF backend. By default, the VRF backend relies on VRF-lite support from the Linux kernel. This option permits discovering Linux named network namespaces and mapping it to FRR VRF contexts.
  44
  45 ROUTES
  46 ------
  47
  48 .. option:: -r, --retain
  49
  50    When the program terminates, do not flush routes installed by zebra from the kernel.
