Configuring OSPFv3
Timers (in milliseconds) LSA and SPF throttling provide a dynamic mechanism to slow LSA
updates in OSPFv3 during times of network instability, and allow faster
OSPFv3 convergence by providing LSA rate limiting. The settings used
to configure LSA pacing and SPF calculation timers are:
LSA Arrival – The minimum delay between acceptance of the same
LSA arriving from neighbors. Valid values range from 0 to
6000000 milliseconds. The default is 1000.
LSA Flood Pacing – The amount of time LSAs in the flooding
queue are paced in between updates. Valid values range from 5 to
100 milliseconds. The default value is 33.
LSA Group Pacing – The interval at which LSAs are collected into
a group and refreshed, check summed, or aged. Valid values range
from 10 to 1800; the default value is 240 milliseconds.
LSA Retransmission Pacing – The length of time at which LSAs in
the retransmission queue are paced. Valid values range from 5 to
200 milliseconds. The default value is 66.
LSA Throttle – The delay in milliseconds to generate the first
occurrence of the LSA. Valid values range from 0 to 600000
milliseconds. When you enter a value in this field, the min and max
fields are enabled:
min – The minimum delay for originating the same LSA. Valid
values range from 1 to 600000 milliseconds.
max – The maximum delay for originating the same LSA.
Valid values range from 1 to 600000 milliseconds.
SPF Throttle – The delay to receive a change to the SPF
calculation. Valid values range from 1 to 600000 milliseconds.
When you enter a value in this field, the min and max fields are
enabled:
min – The delay between the first and second SPF calculations.
Valid values range from 1 to 600000 milliseconds.
max – The maximum wait time for SPF calculations. Valid
values range from 1 to 600000 milliseconds.
Note Note For LSA throttling, if the minimum or maximum time is
less than the first occurrence value, then OSPFv3 automatically
corrects to the first occurrence value. Similarly, if the maximum
delay specified is less than the minimum delay, then OSPFv3
automatically corrects to the minimum delay value.
