Feature Validation and Operation Procedures

The MPLS forwarding policy follows a number of configuration and operation rules which are enforced for the lifetime of the policy.

There are two levels of validation:

• The first level validation is performed at provisioning time. The user can bring up a policy (no shutdown command) once these validation rules are met. Afterwards, the policy is stored in the forwarding policy database.

• The second level validation is performed when the database resolves the policy.
