R3102-R3103-HP 6600/HSR6600 Routers Layer 3 - IP Routing Command Reference

206
Parameters
maximum-interval: Specifies the maximum wait interval for generating IS-IS LSPs, in the range of 1 to 120
seconds.
initial-interval: Specifies the initial wait interval before generating the first IS-IS LSP, in the range of 10 to
60000 milliseconds. The default is 0.
second-wait-interval: Specifies the wait interval before generating the second LSP, in the range of 10 to
60000 milliseconds. The default is 0.
level-1: Applies the intervals to Level-1.
level-2: Applies the intervals to Level-2 .If no level is specified, the specified intervals apply to both Level-1
and Level-2.
Usage guidelines
• If only the maximum interval is specified, IS-IS waits the maximum interval before generating an LSP.
• If both the maximum and initial intervals are specified:
{ IS-IS waits the initial interval before generating the first LSP.
{ If the network topology is unstable—triggers occur at intervals shorter than the maximum
interval, IS-IS waits the maximum interval before generating the first LSP until the network
topology is stable.
• If the maximum, initial, and second wait intervals are specified:
{ IS-IS waits the initial interval before generating the first LSP.
{ If the network topology is unstable—triggers occur at intervals shorter than the maximum
interval, IS-IS waits the second-wait-interval before generating the second LSP and penalty is
applied on the wait interval before generating the next LSP. For each subsequent trigger, the
wait interval before generating the LSP is two times the previous wait interval until the maximum
interval is reached.
{ After the network topology is stable—triggers occur at intervals greater than the maximum
interval, the wait interval before generating LSPs is restored to the initial interval.
Examples
# Set the maximum, initial, and second wait intervals to 10 seconds, 100 milliseconds and 200
milliseconds, respectively.

timer lsp-max-age
Use timer lsp-max-age to set the LSP maximum age in the LSDB.
Use undo timer lsp-max-age to restore the default.
