Associating Affinity Constraints for TE Tunnels
The final step in the configuration of MPLS-TE Flexible Name-based Tunnel Constraints requires that you
associate a tunnel with affinity constraints.
Using this model, there are no masks. Instead, there is support for four types of affinity constraints:
•
include
•
include-strict
•
exclude
•
exclude-all
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
