Abstract: The present technology discloses methods, systems, and non-transitory computer-readable storage media for establishing a redundant path connection. An example method can include configuring a software-defined wide-area network (SDWAN) tunnel between an on-premises router and a plurality of SDWAN routers; configuring a virtual layer 2 connection between the plurality of SDWAN routers and handoff locations for a virtual cloud resource (VCR) associated with at least one VCR tag, wherein a software-defined cloud infrastructure (SDCI) underlay associated with at least one SDCI provider connects to a cloud service provider (CSP) at the handoff locations; configuring a VCR connection between at least one VCR associated with the VCR tag and the handoff locations for the at least one VCR; configuring a border gateway protocol (BGP) session between the plurality of SDWAN routers and the handoff locations; and validating the SDWAN tunnel, the virtual layer 2 connection, the VCR connection, and the BGP session.
