5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide 8-90 timers pacing Isa-group Adjusts how OSPFv3 groups LSAs for the purposes of a periodic refresh. OSPFv3 will refresh selforiginated LSAs around once every 30 minutes. When OSPFv3 refreshes LSAs, it takes into consideration all self-originated LSAs with an age from 1800 to 1800 plus the pacing group size. Grouping the LSAs for a refresh allows OSPFv3 to combine the refreshed LSAs into a minimal number of LS Update packets, which makes LSA distribution more efficient. When OSPFv3 originates a revised or new LSA, it will select a random refresh delay for that LSA. OSPFv3 then refreshes the LSA when the refresh delay expires. Through the selection of a random refresh delay, OSPFv3 avoids the need to refresh a large number of LSAs all at once, even in the event that a large number of LSAs are originated at one time. The window in which LSAs are refreshed is measured in seconds, with the allowed range for the pacing group window being 10 to 1800 seconds. The no command resets the LSA Group Pacing parameter back to the factory default value of 60 seconds. timers pacing lsa-group seconds no timers pacing lsa-group Parameters seconds Default The default is 60 seconds. Command Mode Router OSPFv3 Config Set width of the window for grouping LSAs for refresh (10-1800). 8-91 timers throttle spf The spf-hold value specifies the amount of delay for the initial "wait interval". In the event that an SPF calculation is not scheduled within the current "wait interval", then the next SPF calculation is scheduled at a delay defined by spf-start. If an SPF calculation has been scheduled within the current "wait interval", then the "wait interval" is set to a value equal to two times the current "wait interval" until the "wait interval" hits the maximum time in milliseconds as specified by spf-maximum. Subsequent wait times will then remain at the maximum until such time as the values are reset or an LSA is received in between SPF calculations. The no command resets the SPF throttling parameters back to the factory default values. timers throttle spf spf-start spf-hold spf-maximum no timers throttle spf Parameters spf-start Indicates the SPF schedule delay in milliseconds when no SPF calculation has been scheduled during the current "wait interval". Value range is 1 to 600000 milliseconds. 869
