mpls-reflood-timer pacing
Configures the router to reflood link information at a defined interval.
Syntax: mpls-reflood-timer pacing time jitter percent
no mpls-reflood-timer
time
Specifies the number of seconds or milliseconds the interface waits since the last event that triggered a reflood, before reflooding link information. Valid values are 0.0 to 4294967.00 0 <s | ms> where s is seconds and ms is milliseconds.
jittertime
Specifies the number of seconds to offset to the periodic timer to prevent the recomputation of many LSPs at the same time.
Valid values are 0.0 to 4294967.00 0 <s | ms> where s is seconds and ms is milliseconds.
Description: LSPs are advertised via the updates distributed by the IGP. Advertisements are flooded to the network from this interface using one of two timers:
- The global reflood timer for all interfaces configured using the mpls-reflood-timer method command in Configuration command mode.
- The local reflood timer for only this interface configured using the mpls-te-reflood-timer method command in Interface configuration command mode.
where the method is one of three models: immediate, pacing, or linear.
The pacing model configures the interface to wait the defined interval after the last event that triggered a reflood, before reflooding. The jitter value is added or subtracted from the number of seconds or milliseconds specified by the time. Jitter prevents multiple LSPs from attempting to set up at the same time.
NOTE When IS-IS is the IGP, if one interface reflood timer expires (triggering a reflood), all interfaces are reflooded.
Use the mpls-reflood-timer pacing command to configure the Avici router to advertise LSP using the specified number of seconds or milliseconds and jitter.
Use the no mpls-reflood-timer command to configure the Avici router to advertise LSPs using the default values.
Factory Default: If no value is configured, the factory defaults are used.
Command Mode: Configuration.
Example 1: In the following example, the mpls-reflood-timer pacing command configures the Avici router to reflood link information 20 seconds after the last event that triggered a reflood. To prevent the simultaneous set-up of multiple LSPs, a jitter of 15% of the defined value is configured:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#mpls-reflood-timer pacing 20 s jitter 15%
router(config)#end
router#show interface pos 1/1/1
POS 1/1/1 is up, line protocol is up
.
.
.
Reflood timers: pacing 20000ms jitter 15%
.
.
.
Example 2: In the following example, the no mpls-reflood-timer configures the Avici router to reflood link information using the global value.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface pos 1/1/1
router(config-if)#no mpls-reflood-timer
router(config-if)#end
router#show interface pos 1/1/1
POS 1/1/1 is up, line protocol is up
