Implementing MPLS Traffic Engineering
For the affinity constraints above, all but the exclude-all constraint may be associated with up to 10 colors.
Note
SUMMARY STEPS
1. configure
2. interface tunnel-te tunnel-id
3. affinity {affinity-value mask mask-value | exclude name | exclude -all | include name | include-strict
name}
4. Use the commit or end command.
DETAILED STEPS
Command or Action
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Step 2
interface tunnel-te tunnel-id
Example:
RP/0/RSP0/CPU0:router(config)#
interface tunnel-te 1
Step 3 affinity {affinity-value mask mask-value |
exclude name | exclude -all | include name |
include-strict name}
Example:
RP/0/RSP0/CPU0:router(config-if)#
affinity include red
Step 4 Use the commit or end command.
OL-28381-02
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.
