! 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.

! 68:
! 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.
