Link Coloring

RSVP allows you to configure administrative groups for CSPF path selection. An administrative group is typically named with a color, assigned a numeric value, and applied to the RSVP interface for the appropriate link. Lower numbers indicate higher priority.

After configuring the administrative group, you can either exclude, include, or ignore links of that color in the traffic engineering database:

• If you exclude a particular color, all segments with an administrative group of that color are excluded from CSPF path selection.
• If you include a particular color, only those segments with the appropriate color are selected.
• If you neither exclude nor include the color, the metrics associated with the administrative groups and applied on the particular segments determine the path cost for that segment.

The LSP with the lowest total path cost is selected into the traffic engineering database.
