Abstract
In one embodiment, a method includes acquiring an Internet Protocol version 6 (IPv6) address for a physical interface of a first network element. The method also includes configuring an Internet Protocol version 4 (IPv4) over IPv6 tunnel between the first network element and a second network element using the physical interface of the first network element. The method also includes acquiring an updated IPv6 address for the physical interface of the first network element and using an IPv6 Service Level Agreement (SLA) Hypertext Transfer Protocol (HTTP) operation to notify the second network element of the updated IPv6 address to establish a bidirectional IPv4 over IPv6 tunnel. The method further includes establishing a control connection with an IPv4 SD-WAN controller and automatically building an SD-WAN overlay tunnel with the bidirectional IPv4 over IPv6 tunnel as a transport.
