Abstract: Techniques for providing an extended layer 2 network. Embodiments receive, at a first network device in a first layer 2 network within the extended layer 2 network, a data packet specifying a destination Media Access Control (MAC) address. Upon determining that the destination MAC address is a site virtual MAC (S-VMAC) address, the data packet is forwarded to a second network device in a second layer 2 network within the extended layer 2 network and associated with the S-VMAC address, where the second network device is configured to determine a second destination MAC address for the data packet based on an Internet Protocol (IP) address specified in the data packet, and is further configured to forward the data packet to a destination device associated with the determined second destination MAC address.

Abstract: Techniques for configuring a virtual network device are provided. Embodiments identify a network device profile specifying a virtual link teaming domain. Upon receiving a network message advertising the virtual link teaming domain from a peer network device of the two or more network devices, on a plurality of links of the first network device, the plurality of links are teamed, based on the virtual link teaming domain, to create a first link bundle. Embodiments advertise a virtual link teaming identifier to a neighboring network device of the first network device. Here, the neighboring network device is configured to use the virtual link teaming identifier to bundle links between the neighboring network device and the virtual network device.

Abstract: In some embodiments, a virtual device context (vDC) domain may be advertised to other network devices. If at least a partition of each device is determined to belong to the same vDC domain, the network interface communicating with the at least one device may be activated.

Abstract: Upon receiving a first message, from the second network device, indicating that the second network device is incompatible with one or more virtual local area network (VLAN) pruning techniques, a timer on a first network device is configured to expire after a predetermined period of time. The first network device is configured to maintain a subscription for the second network device to one or more VLANs until the timer expires. The second network device is configured to transmit the first message in response to detecting an upcoming control plane outage at the second device. Prior to the timer expiring, embodiments transmit data assigned to the one or more VLANs to the second network device. Embodiments also periodically receive update messages, from the second network device, identifying one or more VLANs to which the second network device wants to subscribe.
