    摘要: 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.

    摘要: 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.

    摘要: 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.
