Dell Force10 Z9000 - Lsp-Gen-Interval

lsp-gen-interval
Set the minimum interval between successive generations of link-state packets (LSPs).
E-Series, S4810
Syntax
lsp-gen-interval [level-l | level-2] interval seconds
[initial_wait_interval seconds [second_wait_interval seconds]]
To restore default values, use the no lsp-gen-interval [level-l | level-2]
interval seconds [initial_wait_interval seconds
[second_wait_interval seconds]] command.
Parameters
level-l (OPTIONAL) Enter the keywords level-1 to apply the configuration
to generation of Level-1 LSPs.
level-2 (OPTIONAL) Enter the keywords level-2 to apply the configuration
to generation of Level-2 LSPs.
interval seconds Enter the maximum number of seconds between LSP generations.
The range is 0 to 120 seconds. The default is 5 seconds.
initial_wait_interv
al seconds
(OPTIONAL) Enter the initial wait time, in seconds, before running the
first LSP generation. The range is 0 to 120 seconds. The default is 1
second.
second_wait_inte
rval seconds
(OPTIONAL) Enter the wait interval, in seconds, between the first and
second LSP generation. The range is 0 to 120 seconds. The default is
5 seconds.
Defaults Refer to Parameters.

Command History
Version 8.3.12.0 Introduced on the S4810.
Version 7.5.1.0 Added support for LSP Throttling Enhancement.
Usage
Information
LSP throttling slows down the frequency at which LSPs are generated during network
instability. Even though throttling LSP generations slows down network convergence, no
throttling can result in a network not functioning as expected. If network topology is unstable,
throttling slows down the scheduling of LSP generations until the topology regains its stability.
The first generation is controlled by the initial wait interval and the second generation is
controlled by the second wait interval. Each subsequent wait interval is twice as long as the
previous one until the wait interval reaches the maximum wait time specified (interval
seconds). After the network calms down and there are no triggers for two times the
maximum interval, fast behavior is restored (the initial wait time).
