A county fabric uses DHCP relay from the management VRF to a central DHCP server. Why does relay commonly appear in this DC management design?
Select an answer to reveal the explanation.
Short Explanation
When the DHCP server sits in a central VRF and the new leaf is on another management subnet, relay is the courier that forwards the Discover. County fabrics use it so one server can serve many provisioning segments. It is not an EVPN crypto feature or a VXLAN load-balancer.
Full Explanation
DHCP is a broadcast-oriented discovery mechanism within a subnet. When clients and servers sit in different subnets or VRFs—as in centralized municipal management designs—DHCP relay forwards client messages to the server and returns offers appropriately. Relay does not replace the server, encrypt EVPN, or balance VXLAN BUM. Correct relay targets and VRF context are essential troubleshooting points when Discover never becomes Offer across segments.
