Parameters
flood-count flooding-count: Specifies the maximum number of LSPs that can be rapidly flooded before SPF computation is started. The value range for the flooding-count argument is 1 to 15. The default value is 5.
max-timer-interval interval: Specifies the delay before fast flooding is performed. The value range for the interval argument is 10 to 50000 milliseconds. The default value is 10.
Usage guidelines
Fast flooding of LSPs enables ISIS-SPB to flood the specified number of LSPs that invoke SPF before SPF computation is started. This mechanism improves ISIS-SPB convergence time.
Examples
# Enable fast flooding of LSPs, specify the maximum number of fast flooded LSPs to 10, and set the flooding delay to 100 milliseconds.
