Layer 3 connectivity in an EVPN-VXLAN topology

You can deploy a device as a Layer 3 Virtual Extensible LAN (VXLAN) gateway in an EVPN-VXLAN topology with a centrally-routed bridging overlay or an edge-routed bridging overlay. In this role, the device provides Layer 3 connectivity between physical (bare-metal) servers and virtual machines (VMs) within a data center. On these devices, you can configure integrated routing and bridging (IRB) interfaces that route packets between VLANs. While creating an IRB interface, you can configure the interface as a default Layer 3 gateway, which physical servers or VMs in one VLAN use to communicate with physical servers or VMs in another VLAN.
