31: @deffn {OSPF6 Command} {timers throttle spf @var{delay} @var{initial-holdtime} @var{max-holdtime}} {}
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.
