Static IP address assignment configuration example

As shown in Figure 20, Router A (DHCP server) assigns a static IP address, a DNS server address, and a gateway address to Router B (DHCP client) and Router C (BOOTP client).

The client ID of the interface GigabitEthernet 1/0/1 on Router B is:

0030-3030-662e-6532-3030-2e30-3030-322d-4574-6865-726e-6574.

The MAC address of the interface GigabitEthernet 1/0/1 on Router C is 000f-e200-01c0.

1. Specify an IP address for GigabitEthernet 1/0/1 on Router A:

   <RouterA> system-view
   [RouterA] interface gigabitethernet 1/0/1
   [RouterA-GigabitEthernet1/0/1] ip address 10.1.1.1 25
   [RouterA-GigabitEthernet1/0/1] quit
   

2. Configure the DHCP server:

   # Enable DHCP.

   [RouterA] dhcp enable
   

   # Enable the DHCP server on GigabitEthernet 1/0/1.

   [RouterA] interface gigabitethernet 1/0/1
   [RouterA-GigabitEthernet1/0/1] dhcp select server
   [RouterA-GigabitEthernet1/0/1] quit
   

   # Create DHCP address pool 0.

   [RouterA] dhcp server ip-pool 0
   

   # Configure a static binding for Router B.

   [RouterA-dhcp-pool-0] static-bind ip-address 10.1.1.5 25 client-identifier 0030-3030-662e-6532-3030-2e30-3030-322d-4574-6865-726e-6574
   

   # Configure a static binding for Router C.

   [RouterA-dhcp-pool-0] static-bind ip-address 10.1.1.6 25 hardware-address 000f-e200-01c0
   

   # Specify the DNS server and gateway.

   [RouterA-dhcp-pool-0] dns-list 10.1.1.2
   [RouterA-dhcp-pool-0] gateway-list 10.1.1.126
   [RouterA-dhcp-pool-0] quit
   [RouterA]
   

# Verify that Router B can obtain IP address 10.1.1.5 and all other network parameters from Router A. (Details not shown.)

# Verify that Router C can obtain IP address 10.1.1.6 and all other network parameters from Router A. (Details not shown.)

# On the DHCP server, display the IP addresses assigned to the clients.

[RouterA] display dhcp server ip-in-use
