The IP address of VLAN-interface 1 is 10.10.1.1/24 and IP address of VLAN-interface 2 is10.1.1.2/24 that communicates with the DHCP server 10.1.1.1/24. As shown in the figure below, SwitchA forwards messages between DHCP clients and the DHCP server to assign IP addresses in subnet10.10.1.0/24 to the clients.Network diagramFigure 2-4 Network diagram for DHCP relay agentConfiguration procedure# Create DHCP server group 1 and configure an IP address of 10.1.1.1 for it. system-view[SwitchA] dhcp-server 1 ip 10.1.1.1# Map VLAN-interface 1 to DHCP server group 1.[SwitchA] interface Vlan-interface 1[SwitchA-Vlan-interface1] dhcp-server 1
