摘要： This disclosure describes techniques for improved port mirroring over Ethernet Virtual Private Network (EVPN) Virtual eXtensible Local Area Network (VXLAN). For example, a method includes receiving, by a first network device of a plurality of network devices of a leaf and spine network configured with an Ethernet Virtual Private Network and from a second network device of the plurality of network devices, an extended routing message including information indicating the second network device is connected to an analyzer, and wherein the plurality of network devices is configured with a Virtual Local Area Network (VLAN) for which the analyzer is configured to analyze packets. The method also includes configuring, within forwarding information of the first network device and in response to receiving the extended routing message advertised by the second network device, a next hop that specifies packets associated with the VLAN are to be forwarded to the second network device.

摘要： In general, techniques are described for providing Hot-Root Standby in Global Table Multicast (GTM) environments. For example, in such GTM environments, normally a single unicast route to the customer multicast source (“C-Source”) will be available to egress provider edge (PE) routers. As described herein, ingress PE routers may advertise multiple routes to a C-Source, including unicast routes that include Route Import Extended Communities, which are imported by egress PE routers. This enables an egress PE router to have multiple paths to the C-Source, and the egress PE router may generate multiple C-multicast source tree joins for respective ingress PE routers in order to receive respective multicast streams sourced by the C-Source from the ingress PE routers.

摘要： A device may provide information associated with initiating a segmented tunnel to be used to transfer multicast traffic via a network covering a plurality of areas. The device may receive acknowledgement information associated with the segmented tunnel. The acknowledgement information may include information that identifies a number of egress devices, associated with at least one area of the plurality of areas, that are to receive the multicast traffic. The device may determine, based on the acknowledgement information, a total number of egress devices that are to receive the multicast traffic. The device may selectively provide the multicast traffic via the segmented tunnel based on the total number of egress devices that are to receive the multicast traffic.
