Procedure
Step 1 Create a DHCP server group and add DHCP server to the group.
# Create a DHCP server group.
<Quidway> system-view
[Quidway] sysname Switch
[Switch] dhcp server group dhcpgroup1
# Add a DHCP server to the DHCP server group.
[Switch-dhcp-server-group-dhcpgroup1] dhcp-server 10.10.10.1
[Switch-dhcp-server-group-dhcpgroup1] quit
Step 2 Enable the DHCP relay function on the VLANIF interface.
# Create a VLAN and add GE 1/0/0 to the VLAN.
[Switch] vlan 100
[Switch-Vlan100] quit
[Switch] interface gigabitethernet 1/0/0
[Switch-GigabitEthernet1/0/0] port link-type trunk
[Switch-GigabitEthernet1/0/0] port trunk allow-pass vlan 100
[Switch-GigabitEthernet1/0/0] quit
# Enable global DHCP and enable the DHCP relay function on the VLANIF interface.
[Switch] dhcp enable
[Switch] interface vlanif 100
[Switch-Vlanif100] dhcp select relay
[Switch-Vlanif100] quit
Step 3 Create a VPN instance and bind the DHCP server group and VLANIF interface to the VPN
instance.
Issue 01 (2012-03-15)
Create a DHCP server group and add a DHCP server to the group.
Enable DHCP relay on VLANIF 100 so that the Switch functions as the DHCP relay agent.
Create a VPN instance and bind the DHCP server group and VLANIF interface to the VPN
instance.
Bind the specified DHCP server group to VLANIF 100 so that the packets passing VLANIF
100 are forwarded to the specified server.
Name of the DHCP server group
IP addresses of the DHCP servers
Number and IP address of the interface enabled with the DHCP relay function
Name of the VPN instance that the client belongs to
