Timers Pacing Lsa-Group - NETGEAR M6100 Series Reference Manual

in Link State Advertisements (LSAs), which are bundled into Link State Update (LS Update)
packets. To reduce the likelihood of sending a neighbor more packets than it can buffer,
OSPF rate limits the transmission of LS Update packets. By default, OSPF sends up to 30
updates per second on each interface (1/the pacing interval). Use this command to adjust
this packet rate.
Default
33 milliseconds
Format
timers pacing flood milliseconds
Mode OSPFv2 Router Configuration
Parameter Description
milliseconds The average time between transmission of LS Update packets. The range is from 5 ms to 100 ms.
The default is 33 ms.
no timers pacing flood
To revert LSA transmit pacing to the default rate, use the no timers pacing flood command.
Format

Mode OSPFv2 Router Configuration

timers pacing lsa-group

To adjust how OSPF groups LSAs for periodic refresh, use the timers pacing lsa-group
command in OSPFv2 Router Configuration mode. OSPF refreshes self-originated LSAs
approximately 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
60 seconds
Format
timers pacing lsa-group seconds
Mode OSPFv2 Router Configuration
Parameter Description
seconds Width of the window in which LSAs are refreshed. The range for the pacing group window is from 10
to 1800 seconds.
