mpls-reflood-timer immediate
Configures the Avici router to reflood changes in the network immediately.
Syntax: mpls-reflood-timer immediate
no mpls-reflood-timer
Description: MPLS uses the IGP flooding mechanism to distribute information about LSPs to the network. IGPs include timers controlling how often link state information is advertised, or "flooded" to the network. These timers include a minimum time between refloods of both unchanged and new information.
Advertisements are flooded to the network from this Avici router 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 a specific 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.
Immediate reflooding means that the IGP re-advertises immediately after any change in the network. Immediate reflooding is possible in very small networks and useful in test situations.
NOTE In large networks, immediate reflooding can contribute to network instability due to interactions with IGP timers.
When IS-IS is the IGP, if one interface reflood timer expires (triggering a reflood), all interfaces are reflooded.Use the mpls-reflood-timer immediate command in Configuration command mode to set the global reflood timer to flood changes in link information using the immediate model.
Use the no mpls-reflood-timer to set the reflood timer to the factory default.
Factory Default: None. If no global reflood timers are configured, the global default is to flood using the linear model using the factory settings.
Command Mode: Configuration.
Example 1: In the following example:
- The mpls-reflood-timer immediate command configures all interfaces on the Avici router to reflood link information immediately when there is a change in the network.
- The show interface pos command displays the setting:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#mpls-reflood-timer immediate
router(config)#end
router#show interface pos 1/1/1
POS 1/1/1 is up, line protocol is up
.
.
.
Reflood timers: immediate

Example 2: In the following example, the no mpls-reflood-timer configures all interfaces on the Avici router to reflood link information using the factory defaults:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#no mpls-reflood-timer immediate
router(config)#end
router#show interface pos 1/1/1
POS 1/1/1 is up, line protocol is up
.
