{ 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.
