Table 576 lsa-generate command
7.10.10.38 spf-wait
Table 577 spf-wait command
Item Description
Syntax lsa-generate max-lsa-wait [lsa-initial-wait [lsa-second-wait]]
no lsa-generate-interval 
Context configure>service>vprn>ospf>timers
Description This parameter customizes the throttling of OSPF LSA-generation. Timers that determine 
when to generate the first, second, and subsequent LSAs can be controlled with this command. 
Subsequent LSAs are generated at increasing intervals of the lsa-second-wait timer until a 
maximum value is reached. Configuring the lsa-arrival interval to equal or less than the 
lsa-second-wait interval configured in the lsa-generate command is recommended. 
Use the no form of this command to return to the default. 
Default no lsa-generate
Parameters max-lsa-wait ā Specifies the maximum interval, in milliseconds, between two consecutive 
ocurrences of an LSA being generated.
The timer must be entered as either 1 or in millisecond increments. Values entered that do not 
match this requirement will be rejected. 
Values: 1 ā 600000 
Item Description
Syntax spf-wait max-spf-wait [spf-initial-wait [spf-second-wait]]
no spf-wait
Context configure>service>vprn>ospf>timers
Description This command defines the maximum interval between two consecutive SPF calculations in 
milliseconds. Timers that determine when to initiate the first, second, and subsequent SPF 
calculations after a topology change occurs can be controlled with this command. Subsequent 
SPF runs (if required) will occur at exponentially increasing intervals of the spf-second-wait 
interval. For example, if the spf-second-wait interval is 1000, then the next SPF will run after 
2000 milliseconds, and then next SPF will run after 4000 milliseconds, etc., until it reaches the 
spf-wait value. The SPF interval will stay at the spf-wait value until there are no more SPF runs 
scheduled in that interval. After a full interval without any SPF runs, the SPF interval will drop 
back to spf-initial-wait. 
The timer must be entered in increments of 100 milliseconds. Values entered that do not match 
this requirement will be rejected. 
Use the no form of this command to return to the default.
Default no spf-wait
