DHCP Layer 2 relay
If you enable and configure a DHCP relay agent on the switch, some Layer 2 (L2) devices
do not need to connect to a DHCP server on the physical network. A relay agent
automatically populates the gateway IP address (giaddr) field and adds the Relay Agent
Information option to DHCP messages. A DHCP server uses this option for IP addresses
and other assignment policies. A DHCP relay agent is usually an IP routing-aware device,
which is also referred to as a Layer 3 relay agent. In some network configurations, L2
devices must append the Relay Agent Information option because they are closer to
the end hosts.
An L2 device can operate as a bridge only for a network and might not include an IPv4
address on the network. If an L2 device lacks an IPv4 source address, the device cannot
relay packets directly to a DHCP server that is located on another network. In that
situation, the L2 device can append the Relay Agent Information option and broadcast
the DHCP message.
