Mpls trafficeng flooding thresholds up down 0100 Command

What it does: Controls how much available link bandwidth needs to change (in both the up and down directions) for information about that link's bandwidth to be reflooded throughout the network. (See Chapter 3 for a detailed explanation.)

Default setting: 15, 30, 45, 60, 75, 80, 85, 90, 95, 96, 97, 98, 99, and 100 percent, in both the up and down directions

When to tune it: These flooding thresholds are more sensitive to links as they get full. If you have lots of LSPs that reserve 90 percent or more of a link and LSPs that reserve less than 5 percent of a link, you might want to increase the lower-end thresholds to something like 1,2,3,4,5,7,10,12,15.

Recommendation: Yet another knob that is good to know about but bad to fiddle with. Unless you're aware of the sizes and behaviors of your LSPs, you can easily do more harm (lots of unnecessary IGP flooding) than good with this command.
