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).
lsp-mtu
Set the maximum transmission unit (MTU) of IS-IS link-state packets (LSPs). This command only limits the size
of LSPs this router generates.
Syntax

To return to the default values, use the no lsp-mtu command.
