ProSafe M4100 and M7100 Managed Switches timers pacing lsa-group To adjust how OSPF groups LSAs for periodic refresh, use this command in OSPFv2 Router Configuration mode. OSPF refreshes self-originated LSAs once every 30 minutes. When OSPF refreshes LSAs, it considers all self-originated LSAs whose age is from 1800 to 1800 plus the pacing group size. Grouping LSAs for refresh allows OSPF to combine refreshed LSAs into a minimal number of LS Update packets. Minimizing the number of Update packets makes LSA distribution more efficient. When OSPF originates a new or changed LSA, it selects a random refresh delay for the LSA. When the refresh delay expires, OSPF refreshes the LSA. By selecting a random refresh delay, OSPF avoids refreshing a large number of LSAs at one time, even if a large number of LSAs are originated at one time. Default Format Mode 60 seconds timers pacing lsa-group seconds OSPFv2 Router Configuration Parameter seconds Description Width of the window in which LSAs are refreshed.
