Configuring DHCP Relay

1. To configure the DHCP agent ip address on the interface or
delete the ip address, use the following command.
ip dhcp relay agent
no ip dhcp relay agent
Before enabling DHCP Relay to forward user DHCP request to
external DHCP Server, it is needed to configure IP address of
DHCP Agent, which is one of the IP addresses of interfaces
where DHCP Client locates.
External DHCP Server will assign IP address according to IP
address of DHCP Agent to make them in the same subnet.
DHCP reply packet returned to DHCP client by DHCP server is
forwarded by DHCP Agent. Therefore, a route pointing to the
subnet where DHCP Agent locates needs to be configured on
external DHCP Server.
2. To configure the outside DHCP server ip address on the inter-
face or delete outside DHCP Server address on the interface,
use the following command.
ip dhcp relay server
no ip dhcp relay server
Standard forwarding mode conforms to DHCP standard proto-
col. After user obtains corresponding IP address, DHCP process
will not process subsequent unicast interaction any more, such
as security inspection. At the same time, writing ARP table
function is invalid for standard mode. Standard forwarding
mode performance will be better for big consumer number be-
cause it does not deal with the subsequent unicast interaction.
