2.2.3 Configuration Procedure
In this example, the IRF Fabric is comprised of S3600 switches running software
version Release 1510, a Quidway S3552 switch running software version Release
0028 is used as the DHCP snooping-capable switch, and a Quidway S3528 switch
running software version Release 0028 is used as the Lab DHCP server.
For better readability:
The devices in the IRF Fabric are SwitchA, SwitchB, SwitchC, and SwitchD.
The DHCP snooping-capable device is referred to as "Snooping".
The device serving as the Lab DHCP server is referred to as "LAB".
I. Configuring IRF Fabric
The S3600 series support IRF Fabric. You can interconnect four devices to form a
Fabric for centralized management of the devices in the Fabric. For details, see related
sections in the operation manuals for the S3600 series.
II. Configuring the DHCP relay agent
Figure 2-3 Network diagram for DHCP relay agent configuration
Within the IRF Fabric, configuration made on a device can be synchronized to the other
devices. Therefore, configuration is performed on Switch A only in this example.
# Configure to forward the DHCP requests from the Office to the DHCP server in the
HQ.
<SwitchA> system-view
[SwitchA] dhcp-server 1 ip 192.168.0.3
[SwitchA] interface vlan-interface10
[SwitchA-Vlan-interface10] ip address 192.168.10.1 24
[SwitchA-Vlan-interface10] dhcp-server 1
# Configure to forward the DHCP requests from Lab2 to the Lab DHCP server.
[SwitchA-Vlan-interface10] quit
[SwitchA] dhcp-server 2 ip 192.168.17.1
[SwitchA] interface Vlan-interface 25
[SwitchA-Vlan-interface25] ip address 192.168.19.1 24
