Abstract: Disclosed are systems, methods, and computer-readable storage media for synchronizing the secondary vPC node to the primary vPC node in a BFD protocol over a VxLAN channel with a remote node. In some embodiments of the present technology a primary vPC node can receive a packet from the remote node. The primary vPC node can then determine the packet includes either a MAC address corresponding to the primary vPC node or a secondary vPC node, and at least one inner packet identifier. Additionally, the primary networking switch can identify an access control list (ACL) entry from a set of ACL entries based on the at least one inner packet identifier. Subsequently, based on the ACL entry, the primary vPC node can generate a copy of the packet. After which, the primary vPC node can transmit the packet to the secondary vPC node.
