    3: 
    4: @command{ospf6d} is a daemon support OSPF version 3 for IPv6 network.
    5: OSPF for IPv6 is described in RFC2740.

   26: @deffn {OSPF6 Command} {interface @var{ifname} area @var{area}} {}
   27: Bind interface to specified area, and start sending OSPF packets.  @var{area} can
   28: be specified as 0.

   32: @deffnx {OSPF6 Command} {no timers throttle spf} {}
   33: This command sets the initial @var{delay}, the @var{initial-holdtime}
   34: and the @var{maximum-holdtime} between when SPF is calculated and the
   35: event which triggered the calculation. The times are specified in
   36: milliseconds and must be in the range of 0 to 600000 milliseconds.
   37: 
   38: The @var{delay} specifies the minimum amount of time to delay SPF
   39: calculation (hence it affects how long SPF calculation is delayed after
   40: an event which occurs outside of the holdtime of any previous SPF
   41: calculation, and also serves as a minimum holdtime).
   42: 
   43: Consecutive SPF calculations will always be seperated by at least
   44: 'hold-time' milliseconds. The hold-time is adaptive and initially is
   45: set to the @var{initial-holdtime} configured with the above command.
   46: Events which occur within the holdtime of the previous SPF calculation
   47: will cause the holdtime to be increased by @var{initial-holdtime}, bounded
   48: by the @var{maximum-holdtime} configured with this command. If the adaptive
   49: hold-time elapses without any SPF-triggering event occuring then
   50: the current holdtime is reset to the @var{initial-holdtime}.
   51: 
   52: @example
   53: @group
   54: router ospf6
   55:  timers throttle spf 200 400 10000
   56: @end group
   57: @end example
   58: 
   59: In this example, the @var{delay} is set to 200ms, the @var{initial
   60: holdtime} is set to 400ms and the @var{maximum holdtime} to 10s. Hence
   61: there will always be at least 200ms between an event which requires SPF
   62: calculation and the actual SPF calculation. Further consecutive SPF
   63: calculations will always be seperated by between 400ms to 10s, the
   64: hold-time increasing by 400ms each time an SPF-triggering event occurs
   65: within the hold-time of the previous SPF calculation.

   69: @deffn {OSPF6 Command} {auto-cost reference-bandwidth @var{cost}} {}
   70: @deffnx {OSPF6 Command} {no auto-cost reference-bandwidth} {}
   71: This sets the reference bandwidth for cost calculations, where this
   72: bandwidth is considered equivalent to an OSPF cost of 1, specified in
   73: Mbits/s. The default is 100Mbit/s (i.e. a link of bandwidth 100Mbit/s
   74: or higher will have a cost of 1. Cost of lower bandwidth links will be
   75: scaled with reference to this cost).
   76: 
   77: This configuration setting MUST be consistent across all routers
   78: within the OSPF domain.
