provisioning, by a network architecture controller (NAC), a control plane of a first network with a control plane of a second network different from the first network to allow communication between the control plane of the first network and the control plane of the second network;
establishing, by the control plane of the first network, a session between the control plane of the first network and the control plane of the second network;
registering, by the control plane of the first network, nodes of the first network with the control plane of the second network;
providing, by the control plane of the first network to the control plane of the second network, information related to endpoints within the first network; and
monitoring, by the control plane of the second network, connectivity between the control plane of the first network and the control plane of the second network.
