Parameters

flood-count flooding-count: Specifies the maximum number of LSPs that can be fast advertised. The value range for the flooding-count argument is 1 to 15, and the default value is 5.

max-timer-interval flooding-interval: Specifies the delay before fast advertisement is performed. The value range for the flooding-interval argument is 0 to 50000 milliseconds. The default value is 0, which indicates that LSP fast advertisement is performed without delay.

Usage guidelines

LSP fast advertisement enables TRILL to immediately advertise the specified number of LSPs that invoke SPF calculation. This mechanism improves network convergence time.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Enable TRILL LSP fast advertisement, set the maximum number to 10 for fast advertised LSPs, and set the advertisement delay to 10 milliseconds.
