Abstract: Techniques are presented for distributing host route information of virtual machines to routing bridges (RBridges). A first RBridge receives a routing message that is associated with a virtual machine and is sent by a second RBridge. The routing message comprises of mobility attribute information associated with a mobility characteristic of the virtual machine obtained from an egress RBridge that distributes the routing message. The first RBridge adds a forwarding table attribute to the routing message that indicates whether or not the first RBridge has host route information associated with the virtual machine in a forwarding table of the first RBridge. The first RBridge also distributes the routing message including the mobility attribute information and the forwarding table attribute, to one or more RBridges in the network.

Abstract: Techniques provided herein use aggregate endpoints in a virtual overlay network. In general, aggregate endpoints operate as a single receiving entity for certain packets/frames sent between different physical proximities of the virtual overlay network.

Abstract: Techniques are provided for managing movements of virtual machines in a network. At a first switch, a virtual machine (VM) is detected. The VM is hosted by a physical server coupled to the first switch. A message is sent to other switches and it indicates that the VM is hosted by the physical server. When the first switch is paired with a second switch as a virtual port channel (vPC) pair, the message includes a switch identifier that identifies the second switch. A receiving switch receives the message from a source switch in the network comprising a route update associated with the VM. A routing table of the receiving switch is evaluated to determine whether the host route is associated with a server facing the physical port. The message is examined to determine it contains the switch identifier.

Abstract: In some embodiments, a data packet may be received at a leaf switch. A port-channel associated with a destination port for the data packet may be identified, and the data packet may be transmitted to the destination port via the identified port-channel.
