Example: Configuring the Device as a DHCP Server to Support
a Relay Agent
This example demonstrates how to configure the device as a DHCP server, with a relay agent, without hosts or
host groups.
The following topology depicts a scenario where two clients on separate LANs require IP addresses on different
subnets from a DHCP server. Each client connects to the DHCP relay agent using different VLANs. The DHCP relay
agent manages the requests and responses between the clients and the DHCP server.
IMPORTANT!
The values shown are specific to the provided topology. Actual values can vary based on the user's
configuration.
