This disclosure describes techniques for supporting an and Multi-Protocol Label Switching (MPLS)-based Virutal Private Network (VPN) service that provides layer two (L2) connectivity between the customer edge device. In particular, the techniques support a Border Gateway (BGP) MPLS-based MAC VPNs (“MAC-VPN” or “MAC VPN”). The techniques provide a MAC VPN in which L2 MAC address learning occurs in the control plane via inter-device BGP signaling in the control plane rather than the data plane, in response to VPN traffic, as may be typical with other VPN technologies. |
