Abstract
Embodiments herein include systems and methods for providing a mechanism for tunneled data transport within a dual homed access network. A tunnel manager, at a first network connectivity device in a transport network, identifies the transport network configured to interconnect at least two access networks for transporting data traffic between one or more end stations connected to the access networks. The first network connectivity device is coupled to a first access network. The tunnel manager identifies a second network connectivity device. The second network connectivity device is coupled to the first access network to provide the first access network dual homed access to the transport network via the first and second network connectivity devices. The tunnel manager creates a virtual tunnel that connects the first and second network connectivity devices to a third network connectivity device across the transport network. The virtual tunnel defines a same virtual tunnel having multiple paths such that the third network connectivity device learns a single virtual tunnel for device address learning.
