Abstract
The present technology provides a system, method, and computer-readable medium directed to dynamic implementation and management of multi-provider internet access featuring multiple access points across a multi-site overlay network fabric. An aspect of the technology is directed to the implementation of a common fabric-wide Virtual Network (VN) with a unique Internet Instance Identifier (Internet IID) that is dedicated to internet access traffic. Default access routes from multiple service providers (SP) are leaked into the VN with the Internet IID at exit points of the fabric using local Extranet policies. Internet-bound traffic generated from any point within the overlay fabric network is then redirected into the Internet IID, using remote Extranet policies. Internet-bound traffic, once in the Internet IID, follows the SP default access route(s) towards the exit points where SP specific access policies may be applied to the traffic which is then forwarded to the corresponding SP network.
