Abstract: 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.
