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.

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.
