Configuring flooding thresholds
After bandwidths of links regulated by MPLS TE change, CSPF may need to recalculate paths. This tends
to be resource consuming as recalculation involves IGP flooding. To reduce recalculations and flood only
significant changes, you may configure the following two IGP flooding thresholds in percentages:
Up threshold. When the percentage of available-bandwidth increase to the maximum reservable
•
bandwidth exceeds the threshold, the change is flooded.
• Down threshold. When the percentage of available-bandwidth decrease to the maximum
reservable bandwidth exceeds the threshold, the change is flooded.
To configure flooding thresholds:
To do...
Enter system view
Enter MPLS TE tunnel interface view
Configure the up/down thresholds

Specifying the link metric type for tunnel path calculation

Specify the metric type to use for
path calculation of the current
