First Claim
1. A method for verifying and implementing a requested modification to an advertised route in a data communications network, comprising the steps of:
- receiving at a network provisioning system a customer-generated route advertisement modification request to cause one of (a) provisioning a new route advertisement or (b) withdrawal of an existing route advertisement;
validating the new route advertisement when the customer-generated route advertisement modification constitutes provisioning of said new route advertisement and rejecting said new route advertisement if unable to be verified;
entering the customer-generated route advertisement modification into an official routing database to make such route advertisement modification available to providers of network access; and
periodically checking at least one of such providers of network access to verify whether such route advertisement modification remains effective.

Abstract
Route advertisement requests made by a customer are received at route provisioning center (20) to effect either advertisement of a newly provisioned route or withdrawal of an existing route. In the case of a request to advertise a newly provisioned route, the request is subjected to validation, and if unable to be validated, the request is rejected. Upon validation of a new route advertisement, or following receipt of a request to withdraw an existing route advertisement, the customer-entered request is entered into an official routing database (26) for subsequent propagation to network access providers (14, 16 and 18). Periodically, a check is made to verify that the customer-entered request remains active.
