DHCP Relay Network Topology and Workflow

The following example depicts the interaction between a DHCP client and a server:

DHCP Client-Relay-Server Architecture

The following list outlines the operations that the DHCP relay agent performs to forward the message to the server :

• When a client sends a request for the IP address or configuration parameters, the server responds with the details as requested by the client.

  

  Note

  There should be at least one relay agent when client and server are located in different networks.

• A DHCP Relay IPv6 is established only between agents within the context of each VRF and when no cross VRF interaction is present.
