REFRESH TIMER
Syntax
refresh timer TIMERVALUE
no network area
Parameters
TIMERVALUE Specifies a timer value in seconds. The default
refresh time is 10 seconds. Choose a value between
10 and 1,800 seconds.
Description
Use the REFRESH TIMER command to adjust refresh parameters.
As per RFC 2328 (OSPFv2) in the Architectural Constants section, OSPF
requires each LSA to be refreshed by the originating router in every 30
minutes. The REFRESH TIMER command allows you to set the time
interval for LSAs to be refreshed. This is in addition to the default refresh
time of 30 minutes. For example, if the refresh timer value is set to 20
seconds, the OSPF daemon checks the max-age of LSAs after every 20
seconds and sends a request for refreshing LSAs that are reaching their
max-age. Then the OSPF daemon refreshes the specified LSAs in the
request, but keeps sending self-originating LSAs every 30 minutes.
Use the no form of this command to disable this function.
Command Mode
