Configuration Guide
DHCP Relay Configuration
a DHCP server has been selected when the DHCP client sends the DHCP
request message. Here, the DHCP request message includes the optional
server-id. In some particular application circumstances, we need to enable this
option for relay in order to reduce loads on the network server. In this way, the
DHCP request message is only sent to the specified DHCP server, instead of to
every configured DHCP server. This is the DHCP check server-id function.
Configuring DHCP
Configuring the DHCP Relay Agent
To configure the DHCP relay agent, execute the following commands in the
global configurtion mode:
Command
Function
Ruijie (config)#
service dhcp
Enable the DHCP agent.
Ruijie(config)#
no service dhcp
Disable the DHCP agent.
Configuring the IP Address of the DHCP Server
After you have configured the IP address of the DHCP Server, the DHCP
request message received by the device will be forwarded to it. At the same
time, the DHCP response message received from the DHCP server will also be
forwarded to the DHCP Client.
The IP address of the DHCP server can either be configured globally or on the
layer 3 interface. Up to 20 IP addresses can be configured for the DHCP server
in every mode. When the DHCP request message is received from an interface,
the DHCP server of the interface is first used. If no DHCP server is configured
on the interface, the DHCP server globally configured will be used.
The DHCP supports vrf-based relay function by adding the vtf parameter to the
IP address of the DHCP server.
To configure the IP address of the DHCP server, exeute the following
commands in the global configuration mode:
Command
Function
Ruijie(config)#
IP helper-address
[
vrf
word
]
A.B.C.D
Configure the IP address of the DHCP
server globally.
Ruijie(config-if)#
IP helper-address
[
vrf
word
]
A.B.C.D
Configure the IP address of the DHCP
server on the interface. This command
must be set on the layer 3 interface.
