148DHCP relay agent configuration examplesExample: Configuring basic DHCP relay agentNetwork configurationAs shown in Figure 41, configure the DHCP relay agent on Router A. The DHCP relay agent enablesDHCP clients to obtain IP addresses and other configuration parameters from the DHCP server onanother subnet.Because the DHCP relay agent and server are on different subnets, you need to configure static ordynamic routing to make them reachable to each other.DHCP server configuration is also required to guarantee the client-server communication throughthe DHCP relay agent. For DHCP server configuration information, see "DHCP server configurationexamples."Figure 41 Network diagramProcedure# Specify IP addresses for the interfaces.
