   7 *ospf6d* is a daemon support OSPF version 3 for IPv6 network. OSPF for IPv6 is
   8 described in :rfc:`2740`.

  26    Bind interface to specified area, and start sending OSPF packets. `area` can
  27    be specified as 0.

  30 .. clicmd:: timers throttle spf DELAY INITIAL-HOLDTIME MAX-HOLDTIME
  31
  32 .. index:: no timers throttle spf
  33 .. clicmd:: no timers throttle spf
  34
  35    This command sets the initial `delay`, the `initial-holdtime`
  36    and the `maximum-holdtime` between when SPF is calculated and the
  37    event which triggered the calculation. The times are specified in
  38    milliseconds and must be in the range of 0 to 600000 milliseconds.
  39
  40    The `delay` specifies the minimum amount of time to delay SPF
  41    calculation (hence it affects how long SPF calculation is delayed after
  42    an event which occurs outside of the holdtime of any previous SPF
  43    calculation, and also serves as a minimum holdtime).
  44
  45    Consecutive SPF calculations will always be seperated by at least
  46    'hold-time' milliseconds. The hold-time is adaptive and initially is
  47    set to the `initial-holdtime` configured with the above command.
  48    Events which occur within the holdtime of the previous SPF calculation
  49    will cause the holdtime to be increased by `initial-holdtime`, bounded
  50    by the `maximum-holdtime` configured with this command. If the adaptive
  51    hold-time elapses without any SPF-triggering event occuring then
  52    the current holdtime is reset to the `initial-holdtime`.::
  53
  54       router ospf6
  55        timers throttle spf 200 400 10000
  56
  57
  58    In this example, the `delay` is set to 200ms, the initial holdtime is set
  59    to 400ms and the `maximum holdtime` to 10s. Hence there will always be at
  60    least 200ms between an event which requires SPF calculation and the actual
  61    SPF calculation. Further consecutive SPF calculations will always be
  62    seperated by between 400ms to 10s, the hold-time increasing by 400ms each
  63    time an SPF-triggering event occurs within the hold-time of the previous
  64    SPF calculation.

  67 .. clicmd:: auto-cost reference-bandwidth COST
  68
  69 .. index:: no auto-cost reference-bandwidth
  70 .. clicmd:: no auto-cost reference-bandwidth
  71
  72    This sets the reference bandwidth for cost calculations, where this
  73    bandwidth is considered equivalent to an OSPF cost of 1, specified in
  74    Mbits/s. The default is 100Mbit/s (i.e. a link of bandwidth 100Mbit/s
  75    or higher will have a cost of 1. Cost of lower bandwidth links will be
  76    scaled with reference to this cost).
  77
  78    This configuration setting MUST be consistent across all routers
  79    within the OSPF domain.
