DETAILED STEPS
Purpose
Command or Action
Specifies a manual switchover for path protection for a GMPLS optical LSP.
The tunnel ID is configured for a switchover.
mpls traffic-eng path-protection
switchover
{
gmpls tunnel-name
|
tunnel-te
tunnel-id
}
Step 1
The
mpls traffic-eng path-protection switchover
command must be issued
on both head and tail router of the GMPLS LSP to achieve the complete path
switchover at both ends.
Example:
RP/0/RP0/CPU0:router#
mpls
traffic-eng path-protection
switchover tunnel-te 1
commit
—
Saves the configuration changes and remains within the configuration
session.
Use the
commit
or
end
command.
Step 2
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 session, without committing the
configuration changes.
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 268
2
Associating Affinity-Names with TE Links, on page 270
3
Associating Affinity Constraints for TE Tunnels, on page 271
Assigning Color Names to Numeric Values
The first task in enabling the new coloring scheme is to assign a numerical value (in hexadecimal) to each
value (color).
An affinity color name cannot exceed 64 characters. An affinity value cannot exceed a single digit. For
example, magenta1.
