    Abstract: A provider edge device may receive a first MAC/IP route advertisement that identifies a MAC route, or a MAC and IP route, relating to an endpoint device. The provider edge device may generate and provide a MAC/IP route proxy advertisement based on the MAC route or the MAC and IP route, detect a potential decrease in reliability of the MAC route or the MAC and IP route, broadcast a request to verify the reliability of the MAC and IP route, determine whether the reliability of the MAC route, or the MAC and IP route, has decreased, and perform an action to cause withdrawal of the MAC/IP route proxy advertisement, or to cause a second MAC/IP route advertisement that identifies the MAC route, or the MAC and IP route, to be provided, based on determining whether the reliability of the MAC route, or the MAC and IP route, has decreased.

    Abstract: This disclosure describes techniques for utilizing VXLANs within a network, such as a data center, for transporting L2 customer communications. Moreover, the disclosure describes techniques for auto-discovering, for each VXLAN, a corresponding replication node for replicating and distributing unknown destination, broadcast, and multicast frames to VXLAN Tunnel Endpoints (“VTEPs”) within the data center. Further, the techniques facilitate, by the replication node, discovery and auto-registration of the VTEPs for the respective customer network. As such, the techniques may facilitate configuration of VXLANs without necessarily relying on multicast protocols to provide such functionality. In this way, the techniques described herein may be used to supplement or even replace reliance on multicast protocols, such as the Protocol Independent Multicast (PIM) protocol, when configuring VXLANs within a network.

    Abstract: Techniques are described for providing fast reroute for traffic in EVPN-VXLAN. For example, a backup PE device of an Ethernet segment is configured with an additional tunnel endpoint address (“reroute tunnel endpoint address”) for a backup path associated with a second split-horizon group that is different than a tunnel endpoint address and first split-horizon group for another path used for normal traffic forwarding. The backup PE device sends the reroute tunnel endpoint address to a primary PE device of the Ethernet segment, which uses the reroute tunnel endpoint address to configure a backup path to the backup PE device over the core network. For example, the primary PE device may install the reroute tunnel endpoint address within its forwarding plane and one or more operations to cause the primary PE device to encapsulate a VXLAN header including the reroute tunnel endpoint address when rerouting the packet along the backup path.

    Abstract: The problem of looping at the egress of a transport network with a CE multihomed to a protected egress PE and a backup/protector egress PE can be avoided by (a) enabling the protector egress PE to distinguish between fast reroute (FRR) traffic coming from the protected egress PE and normal known unicast (KU) traffic coming from a PE of the transport network that is not attached to the same multihomed segment; (b) receiving, by the protector egress PE, known unicast data, to be forwarded to the CE; (c) determining, by the protector egress PE, that a link between it and the CE is unavailable; and (d) responsive to determining that the link between the protector egress PE and the CE is unavailable, (1) determining whether the known unicast traffic received was sent from the protected egress PE or from another PE of the transport network that is not attached to the same multihomed segment, and (2) responsive to a determination that the known unicast traffic received was sent from the protected egress PE, discarding the known unicast traffic received, and otherwise, responsive to a determination that the known unicast (KU) traffic received was sent from another PE of the transport network that is not attached to the same multihomed segment, sending the known unicast traffic, via a backup tunnel, to an egress PE which protects the protector egress PE.

    Abstract: A device may include one or more processors. The device may receive an instruction identifying a set of objects to be generated by a kernel associated with the device. The kernel may generate the set of objects based on receiving information identifying a corresponding set of write operations. The device may provide a first message to cause the kernel to perform first operations corresponding to a first subset of objects of the set of objects. The device may receive one or more notifications indicating whether each operation, of the first operations, was successfully performed. The device may determine, based on whether each operation was successfully performed, a quantity of objects to include in a second subset of objects, of the set of objects. The device may provide a second message to cause the kernel to perform second operations corresponding to the second subset of objects.

    CPC classification number: H04Q9/00

    Abstract: A method includes receiving, by a network analyzer implemented in circuitry, from a network device of a plurality of network devices, a sensor message for telemetry flow data. The sensor message indicates an interface index for a network interface, a virtual network identifier associated with a virtual network, and an IP address. The method further includes receiving, by the network analyzer, from the network device, a telemetry flow message for the telemetry flow data. The method further includes, in response to determining that the telemetry flow message includes an indication of an interface index that matches the interface index of the sensor message and that the telemetry flow message includes an indication of a virtual network identifier that matches the virtual network identifier of the sensor message, setting, by the network analyzer, the IP address as the source of the telemetry flow data.
