Abstract: A method for transmitting MAC frames. The method includes receiving, by a first switch in the MLAG domain, a first media access control (MAC) frame from an external device, wherein the external device is directly connected to the first switch, where the MLAG domain consists of the first switch and the second switch. The method further includes making a first determination that the external device is not a singly-connected external device and based on the first determination, encapsulating the first MAC frame in a first VXLAN frame using a first virtual tunnel endpoint (VTEP), where the first VXLAN frame comprises a virtual VTEP Internet Protocol (IP) address, where the virtual VTEP IP address is associated with the MLAG domain. The method further includes transmitting the first VXLAN frame to an IP fabric, where the first switch is directly connected to the IP fabric.

Abstract: In general, embodiments of the invention relate to a method of programming a data plane forwarding information base (FIB). The method includes obtaining, by a FIB entry optimizer in a control plane, a new entry to be loaded into the data plane FIB, making a first determination, by the FIB entry optimizer, that the data plane FIB is not full; and based on the first determination: loading, by the FIB entry optimizer, the new entry into the data plane FIB.

Abstract: A method and apparatus of a device that notifies another device of a failed device is described. In an exemplary embodiment, a network element detects that a first device is unavailable, where the network element couples the first device to the second device. In response to detecting that the first device is unavailable, the network element configures a proxy for the first device. The network element additionally receives network data that is destined for the first device, where the second device originated the network data. If the proxy can process the network data, the network element transmits a response to the second device from the proxy, where the response indicates that the first device is unavailable, where the first response includes an address of the first device. If the proxy cannot process the network data, the network element drops the network data.

Abstract: A method and system for sharing host entries between virtual tunnel endpoints (VTEPs). The method includes making a first determination that an NLHE is present in a locally learned host entry table on a VTEP where the NHLE is associated with a first timestamp, and making a second determination that a first entry corresponding to the NHLE is present in a Host-Specific Portion of Global Host Entry Table (HSPT) on the VTEP, where the first entry is associated with a second timestamp. Based on the second determination, making a third determination, using the timestamps, that the NHLE is more recent than the first entry and based on the third determination updating an active forwarding table on the first VTEP to include a second entry corresponding to the NHLE and to remove the first entry and sending the NHLE to a VXLAN controller operatively connected to the VTEP.

Abstract: In general, embodiments of the invention relate to routing packets between hosts or virtual machines in different layer 2 domains. More specifically, embodiments of the invention relate to using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between hosts or virtual machines in different layer 2 domains to communication. The overlay routing mechanisms may include direct routing, indirect routing, naked routing, or a combination thereof (e.g., hybrid routing).

Abstract: A method for active network fabric management. The method includes receiving a probe packet by a termination beacon, where the probe packet is associated with a stream, the stream is identified using an origin beacon identification (ID) for an origin beacon, a stream source IP address, a stream destination IP address, an L2 origin interface, and a TTL value or an IP Hop value. The method further includes generating, after receiving the probe packet and after the expiration of a probe rate request (PRR) refresh timer, a rate control packet (RCP) by the termination beacon where the RCP includes a PRR for the stream, and sending the RCP to the origin beacon using an origin beacon IP address, where the origin beacon IP address is different than the stream source IP address.
