    Abstract: A system and a method for providing conversational learning is implemented in a network environment. An exemplary method includes receiving a subnet route advertisement that includes an attribute that triggers glean behavior for routing decisions; and installing a subnet entry in a Forwarding Information Base/Adjacency (FIB/ADJ) table. The subnet entry includes a subnet associated with the subnet route advertisement and a corresponding glean adjacency. The corresponding glean adjacency is configured to trigger installation of a host entry associated with a host in an active conversation in a network.

    Abstract: At a physical device in a network configured to host a virtual switch and one or more virtual machines, a packet is received at the virtual switch from a source virtual machine that is directly attached to that virtual switch. A destination Media Access Control (MAC) address is identified from the packet indicating a destination virtual machine for the packet. In response to determining that the destination MAC address of the packet is not present in a database of MAC addresses accessible by the virtual switch, the destination MAC address of the packet is replaced with a shared MAC address associated with a plurality of physical switches in the network.

    Abstract: Systems, methods, and computer-readable media for OAM in overlay networks. In response to receiving a packet associated with an OAM operation from a device in an overlay network, the system generates an OAM packet. The system can be coupled with the overlay network and can include a tunnel endpoint interface associated with an underlay address and a virtual interface associated with an overlay address. The overlay address can be an anycast address assigned to the system and another device in the overlay network. Next, the system determines that a destination address associated with the packet is not reachable through the virtual interface, the destination address corresponding to a destination node in the overlay network. The system also determines that the destination address is reachable through the tunnel endpoint interface. The system then provides the underlay address associated with the tunnel endpoint interface as a source address in the OAM packet.

    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.

    Abstract: In accordance with one example embodiment, there is provided a system configured for virtual local area network (VLAN) blocking on a virtual port channel (vPC) member link to handle discrepant virtual network instance (VNI) to VLAN mappings. In other embodiments, the system can be configured for providing Virtual Switch Interface Discovery Protocol (VDP) and virtual switch enhancements to accommodate discrepant VNI to VLAN mappings. In another example embodiment, an apparatus is provided that includes a processor, and a memory coupled to the processor, where the apparatus is configured such that if a server is connected through a virtual port channel, a VDP is used to notify the server of different VNI to VLAN mappings. In another embodiment, the apparatus can extend a VDP Filter Info Field to carry a set of VLANs mapped to a VNI, keyed by leaf MAC addresses that serve as bridge identifiers.
