Item Description
Syntax timers
Context configure>service>vprn>ospf
Description This command enables the context that allows for the configuration of OSPF timers. Timers 
control the delay between receipt of a link state advertisement (LSA) requiring a Dijkstra 
(Shortest Path First (SPF)) calculation and the minimum time between successive SPF 
calculations. 
Changing the timers affect CPU utilization and network reconvergence times. Lower values 
reduce convergence time but increase CPU utilization. Higher values reduce CPU utilization 
but increase reconvergence time.
Default None
Item Description
Syntax lsa-arrival lsa-arrival-time
no lsa-arrival
Context configure>service>vprn>ospf>timers
Description This parameter defines the minimum delay that must pass between receipt of the same Link 
State Advertisements (LSAs) arriving from neighbors. It is recommended that the neighbors 
configured (lsa-generate) lsa-second-wait interval is equal or greater then the lsa-arrival-time 
configured here. 
Use the no form of this command to return to the default. 
Default no lsa-arrival
Parameters lsa-arrival-time — Specifies the timer in milliseconds. Values entered that do not match this 
requirement will be rejected. 
Values: 0 — 600000
