If a response (DHCP offer) comes back from a DHCP server without Option 82, Requests that it proxies on behalf of clients. When the ACI fabric acts as a DHCP relay, it inserts the DHCP Option 82 (the DHCP Relay Agent Information Option) in DHCP When Layer 2 flooding is disabled, DHCP Relay is required. Server is in a different EPG or Virtual Routing and Forwarding (VRF) instance than the clients, DHCP Relay is required. Within a bridge domain is enabled by default, clients can connect to DHCP servers within the same EPG. This chapter contains the following sections:Īlthough ACI fabric-wide flooding is disabled by default, flooding within a bridge domain is enabled by default.
