EVPN-MPLS: DHCP relay in an EVPN-MPLS network

You can configure a DHCP relay agent on spine devices that perform EVPN Layer 2 and Layer 3 functions in a data center. This is a centrally-routed bridging architecture where the spine devices are connected to a layer of leaf devices that perform EVPN Layer 2 functions. In this architecture, DHCP clients are connected to leaf devices, and DHCP servers are connected to spine devices. The DHCP relay functions are centralized at the spine layer.
