Configuring the DHCP Relay Agent
The Dynamic Host Configuration Protocol (DHCP) servers provide configuration
parameters to DHCP clients. When DHCP clients and associated servers do not
reside on the same IP network or subnet, a DHCP relay agent can transfer DHCP
messages between them. To configure a DHCP relay agent on a CSS, define
DHCP server destinations on a circuit and enable the DHCP relay agent on the
circuit.
You must first assign an IP address on the circuit to be able to configure the DHCP
relay agent for the circuit. Use the ip address command in the specific circuit
mode to assign the IP address and a subnet mask. For example:
(config-circuit[VLAN2])# ip address 178.3.6.53/8
This chapter contains the following major sections:
• DHCP Relay Agent Configuration Quick Start
• Enabling and Disabling DHCP on the Circuit
• Defining the Hops Field Value for Forwarding DHCP Messages
• Displaying the DHCP Relay Configuration
