    Abstract: Presented herein are techniques to handle data packets received at a top-of-rack (ToR) switch in an underlay network hosting one or more tenant networks. The underlay network may comprise a plurality of ToR switches each connected to each of a plurality of spine switches. The data packet may be received from a virtual machine in a tenant network, and have a header with a data packet identifier. A mobility domain identifier may be determined that corresponds to the network portion within which the virtual machine can be migrated. The mobility domain may be configured on the ToR switch on a per-port basis based on the virtual machine connected to the ToR switch port. A unique identifier may be formed based on the data packet identifier and mobility domain identifier. Using this unique identifier, provisioning information may be obtained for the tenant network on the ToR switch.

    Abstract translation: 这里提出的是处理在托管一个或多个租户网络的底层网络中的机架顶部（ToR）交换机处接收的数据分组的技术。 底层网络可以包括多个ToR开关，每个ToR开关连接到多个脊柱开关中的每一个。 可以从租户网络中的虚拟机接收数据分组，并具有具有数据分组标识符的报头。 可以确定对应于可以迁移虚拟机的网络部分的移动性域标识符。 基于连接到ToR交换机端口的虚拟机，每个端口可以在ToR交换机上配置移动性域。 可以基于数据分组标识符和移动性域标识符形成唯一标识符。 使用该唯一标识符，可以为ToR交换机上的租户网络获取供应信息。

    Abstract: Techniques are presented herein for distributing address information of host devices in a network. At a first router device, a packet is received from a first host device that is destined for a second host device. The first host device is dually-connected to the first router and a second router device. The second router device is part of a virtual port channel pair with the first router device. A message is sent to the second router device, the message indicating that the first host device is connected to the second router device. The packet is encapsulated with an overlay header and is sent to a third router device that is connected to the second host device. The encapsulated packet contains a Layer 2 address associated with the first host device and a Layer 3 address associated with the first host device.

    Abstract: An addressing redirection mechanism is initiated at a first networking device in a computing network in order to enable the first networking device to perform one or more distributed proxy addressing operations on behalf of a connected second networking device. An address request transmitted from a first host device to a second host device to obtain addressing information of the second host device is received at the first networking device, and the first networking device inspects the address request to identify addressing information for the first host device. The first networking device is configured to forward the addressing information for the first host device to the second networking device.

    Abstract: A method is provided in one example embodiment and includes determining a source of a packet received at a network element and characterizing a link on which the packet was received. The method further includes forwarding the packet to an overlay network and locally connected hosts other than a source of the packet if the source of the packet is a local host and the link is a local link; forwarding the packet to hosts that are not dually-connected to the network element if the source of the packet is the local host and the link is a core link; and forwarding the packet as indicated in a multicast tree if the source of the packet is a non-local host and the link is a core link.

    Abstract: Techniques are provided for provisioning network resources for virtual machines. At a first switch device, a configuration request message is received from a virtual switch to provision virtual network segmentation resources for a virtual machine managed by the virtual switch. The first switch device provisions the virtual network segmentation resources for the virtual machine. The first switch devices sends to a second switch device a first synchronization message that includes information describing the virtual network segmentation resources. The second switch device is a peer of the first switch device. The first switch device also sends to the second switch device a second synchronization message that includes state information indicating that the first switch device is in an active state for servicing the virtual machine and that the second switch device is to be placed in a dormant state for servicing the virtual machine.

    Abstract: A leaf switch of a switch fabric includes multiple ports to connect with respective ones of multiple servers. Virtual local area networks (VLANs) are configured on the leaf switch. Dynamic creation of virtual ports is enabled on the leaf switch for at least one of the VLANs on an as needed basis. The leaf switch receives from a particular server connected to a corresponding one of the ports a notification message that a virtual machine is hosted on the particular server. Responsive to the notification message, the leaf switch dynamically creates a virtual port that associates the corresponding one of the ports with the at least one of the VLANs.
