8.3.11.1 Introduced on the Z9000.
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 rst 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 specied (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
lsp-mtu size
To return to the default values, use the no lsp-mtu command.
Parameters
size The maximum LSP size, in bytes. The range is from 512 to 16000 for Non-Jumbo
mode and from 128 to 9195 for Jumbo mode. The default is 1497.
NOTE: The appropriate interface circuit is brought down and removed.
Defaults 1497 bytes.
Command Modes ROUTER ISIS
