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

  24 .. clicmd:: interface IFNAME area AREA
  25
  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 separated 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 occurring then
  52    the current holdtime is reset to the `initial-holdtime`.

  57        timers throttle spf 200 400 10000
  58
  59
  60    In this example, the `delay` is set to 200ms, the initial holdtime is set
  61    to 400ms and the `maximum holdtime` to 10s. Hence there will always be at
  62    least 200ms between an event which requires SPF calculation and the actual
  63    SPF calculation. Further consecutive SPF calculations will always be
  64    separated by between 400ms to 10s, the hold-time increasing by 400ms each
  65    time an SPF-triggering event occurs within the hold-time of the previous
  66    SPF calculation.

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