Dynamic host configuration protocol helps us to address dynamically our hosts on the network. Configuring dhcp relay agents helps to reduce the number of dhcp servers on your networks, making the task of ip address mangement less complicated. A dynamic host configuration protocol (dhcp) relay agent is a host or ip router that relays dhcp packets between dhcp clients and dhcp servers.

This module describes the concepts and tasks configuring support for relay agent information option encapsulation. Configure the dhcp relay agent to insert the option 82 field to dhcp messages in an interface view. Before configuring a dhcp relay agent, make sure you have configured a layer 3 ethernet or layer 3 vlan interface, and the interface is assigned to a virtual router and a zone. This wikihow teaches you how to enable your router's dynamic host configuration protocol (dhcp). Finally, configure dhcp relay agent a dhcp relay agent allows dhcp clients in a different network subnet to lease ip addresses. To prepare for dhcp relay agent configuration, configure routing and remote access. Now, the ip helper address command is used for configuring the router as a dhcp relay agent, giving 192.168.2.2 the address of dhcp_server.
Configure the dhcp relay agent for ipv4. Let us consider that you have several ip networks 'behind' other routers, but you want to keep all dhcp servers on a single router. This command instructs the router. When server replies back to the relay agent with the dhcpoffer message how will this message be sent to client, broadcast or unicast? This configuration takes effect on dhcp messages received on the specified interface.

At this point, the dhcp relay agent stores its ip address. In fact, when a host is configured to get its ip address dynamically, it will broadcast a dhcp request on the network searching for a dhcp server.
The helper addresses are shared between the dhcp relay agent and udp forwarder feature.
Use the following methods to configure strategies for processing option 82 information. Before configuring a dhcp relay agent, make sure you have configured a layer 3 ethernet or layer 3 vlan interface, and the interface is assigned to a virtual router and a zone. In the following section i will show you how to configure a cisco 851 or 871 router to work as dhcp server. Acting as a dhcp relay agent , router transform dhcp request from broadcast to unicast going to dhcp server and vice versa. I know a router acting as a relay agent sends the dhcp messages from client to the dhcp server. At this point, the dhcp relay agent stores its ip address. The dhcp relay service allows you to pass dhcp broadcast messages to network segments that a client computer is not directly attached to. For mx series routers connected via irb, see the note below to prevent bootp reply packets from being dropped. Configure the dhcp relay agent for ipv4. Setting the gateway address of the dhcp broadcast to a secondary address. The dhcp server will assign ip addresses in the same subnet. The dhcp relay agent works with ipv4 and ipv6 addresses. The dhcp relay agent is located between a pc and dhcp server as shown in figure 2.
This wikihow teaches you how to enable your router's dynamic host configuration protocol (dhcp). The dhcp relay agent is located between a pc and dhcp server as shown in figure 2. The demonstration is done with. So how can we solve this? To configure a router's interface as a dhcp relay agent, use the following command in interface configuration mode.

To rectify this, we can configure r1 to act as a dhcp relay agent and forward the request to the configured dhcp server. For this lab, my core router is going to be configured to serve as a dhcp server to the two local area networks attached to site1 and site2. Configure the dhcp relay agent to insert the option 82 field to dhcp messages in an interface view. A dynamic host configuration protocol (dhcp) relay agent is a host or ip router that relays dhcp packets between dhcp clients and dhcp servers. Adds dhcp relay agent information if enabled according to rfc 3046. All interfaces used for the dhcp relay must be configured.
You should configure the router, switch, or interface to be a dhcp and bootp relay agent if you have locally attached hosts and a distant dhcp or bootp server.
In fact, when a host is configured to get its ip address dynamically, it will broadcast a dhcp request on the network searching for a dhcp server. This module describes the concepts and tasks configuring support for relay agent information option encapsulation. The default relay agent ip address will not take effect. like the router is acting like a proxy between user and dhcp server. The demonstration is done with. This configuration takes effect on dhcp messages received on the specified interface. Now, the ip helper address command is used for configuring the router as a dhcp relay agent, giving 192.168.2.2 the address of dhcp_server. The dhcp relay agent transfers dhcp messages from dhcp clients located on a subnet without a dhcp server to other subnets. I know a router acting as a relay agent sends the dhcp messages from client to the dhcp server. The dynamic host configuration protocol (dhcp) provides a mechanism for passing configuration information to hosts on a tcp/ip network. The helper addresses are shared between the dhcp relay agent and udp forwarder feature. So how can we solve this?
