Use Case Overview

Enterprise networks are adopting IP Fabric at the core and distribution layers as underlay and use an EVPN-VXLAN as overlay network to provide Layer 3 or Layer 2 connectivity.

Data center environments require Dynamic Host Configuration Protocol (DHCP) relay to pass DHCP messages between DHCP Clients and a DHCP Server. The DHCP Relay is typically configured at the subnet default gateway.


DHCP is an essential component of any data center deployment. DHCP Relay requirements in the data center fabric may vary based on the unique requirements in a given data center deployment. Juniper’s data center fabric architectures based on EVPN-VXLAN provide the necessary flexibility to customize DHCP Relay configuration to address most of these requirements.
