Abstract
Methods and apparatus to dynamically control access from VPNs to shared resources are disclosed. A disclosed example route reflector comprises a memory to implement a database, a user interface module to receive a request to permit access for a VPN to a shared resource, a BGP engine to process BGP advertisements, a network interface to receive a first BGP advertisement from a PE router associated with the VPN that includes a first RT associated with the VPN, and a shared resource access controller to update the database based on the request, to query the database to determine whether the VPN has access to the shared resource in response to the first BGP advertisement, and to direct the BGP engine to form a second BGP advertisement based on the first BGP advertisement that includes a second RT associated with the shared resource when the VPN has access to the shared resource.
