Static Anycast Gateway

Static Anycast Gateway for EVPN/VXLAN is a default IP gateway addressing mechanism that enables the use of the same VLAN and the same gateway IP and MAC addresses across all the leaf switches that are part of the same L3 VNI in a VXLAN network. There is a 1:1 mapping between VNI ID and VLAN ID. This ensures that every leaf switch can function as the default gateway for the workloads directly connected to it from host machines. The feature facilitates flexible workload placement, mobility of host virtual machines, and optimal traffic forwarding across the VXLAN fabric. This feature should be used together with VXLAN EVPN.
