It provides background by reviewing the growing pains that commonly faced today by enterprise for its flexiable WAN sites connection. It assumes that WAN connection services are and will continue to be provided by multiple underlay networks operated by different administrative entities. Based on the pains and the assumptions, this document propose to use SRv6 binding SIDs (BSIDs) on a transport network (TN) edge router as NPI for service provisioning to be accessed remotely and securely by a customer router that constitutes to a higher overlay network, including the requirements of such service, the illustration of how it may work, and the possible applicability of the solution.}, }
