Configuring Flexible Name-based Tunnel Constraints

To fully configure MPLS-TE flexible name-based tunnel constraints, you must complete these high-level
tasks in order:
1 Assigning Color Names to Numeric Values, on page 184
OL-28381-02
Purpose
Enters global configuration mode.
Enters MPLS-TE configuration mode.
Ignores the Intermediate System-to-Intermediate System (IS-IS)
overload bit setting for MPLS-TE.
If set-overload-bit is set by IS-IS on the head router, the tunnels stay
up.
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.
