Configuring IS-IS to Flood MPLS-TE Link Information
Perform this task to configure a router running the Intermediate System-to-Intermediate System (IS-IS)
protocol to flood MPLS-TE link information into multiple IS-IS levels.
This procedure shows how to enable MPLS-TE in both IS-IS Level 1 and Level 2.

Purpose
Enters global configuration mode.
Configures an MPLS-TE tunnel interface.
Configures link attributes for links comprising a tunnel. You can have
up to ten colors.
Multiple include statements can be specified under tunnel configuration.
With this configuration, a link is eligible for CSPF if it has at least a red
color or has at least a green color. Thus, a link with red and any other
colors as well as a link with green and any additional colors meet the
above constraint.
commit—Saves the configuration changes, and remains within the
configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration
session.
• No—Exits the configuration session without committing the
configuration changes.
• Cancel—Remains in the configuration mode, without committing
the configuration changes.
