Deployment Process
Logically, networks in the EVPN Interconnection Solution can be divided into three layers from bottom to top: physical network (underlay network) layer, virtual network (overlay network) layer, and service policy layer. During network planning and deployment, configure the physical network, deploy the virtual network, and then deploy service policies based on service requirements. You can refer to the deployment process in the following figure to deploy the EVPN Interconnection Solution.
