Abstract: In accordance with one example embodiment, a system configured for programming a network layer multicast address entry in a routing table of an ingress line card module is disclosed. The network layer multicast address entry includes a network layer address associated with at least one egress line card. The system is further configured for programming a data link layer multicast routing address entry in a routing table of a fabric card module in which the data link layer multicast routing address entry corresponds to the network layer multicast address entry.

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.

Abstract: A method is provided in one example embodiment and includes receiving at a controller an Address Resolution Protocol (“ARP”) packet from a source VXLAN Tunnel End Point (“VTEP”) serving a source host and identifying a destination, the source VTEP having assigned thereto a Virtual Network Identifier (“VNI”) identifying a VXLAN network to which the source VTEP and a plurality of other VTEPs belong, the ARP packet being received by the controller via a control plane; determining whether the received ARP packet is a request message; and, if the received ARP packet is a request message, determining whether address information for the identified destination is stored in a cache of the controller.

Abstract: Systems, methods, and computer-readable storage media for configuring a virtual port channel (VPC) domain. The disclosed technology involves determining that a first switch and a second switch are connected in a VPC domain, determining that the first switch is in a primary role, and determining a unique identifier for the first switch, a VPC portchannel number for the first switch, and an orphan port number for the first switch. Also, the first switch receives a unique identifier, a VPC portchannel number, and an orphan port number for the second switch. The first switch can associate the VPC portchannel number for the second switch and the VPC portchannel number for the first switch with a unified VPC portchannel number and create a first unique orphan port number for the first switch and a second unique orphan port number for the second switch.
