Abstract
According to certain embodiments, control packets are received through a control plane tunnel that communicates control traffic for virtual private networks (VPNs) among autonomous systems. A routing instance of each control packet is identified according to a control tag of the control packet. At least two routing instances are distinct from each other. The control packets are routed according to the routing instances. According to certain embodiments, data packets are received through a data plane tunnel that communicates data traffic for the VPNs among the autonomous systems. A forwarding instance of the control packet is identified for each data packet according to a data tag of the data packet. At least two forwarding instances are distinct from each other. The data packets are forwarded according to the forwarding instances.
