Automatic configuration using TFTP server

As shown in Figure 35, Router B does not have a configuration file.

Configure the servers so Router B can obtain a configuration file to complete the following configuration tasks:

• Enable the administrator to Telnet to Router B to manage Router B.

• Require the administrator to enter the correct username and password at login.

1. Configure the DHCP server:

   # Enable DHCP.

   <RouterA> system-view
   [RouterA] dhcp enable
   

   # Configure the address pool 1 to assign IP addresses on the subnet 192.168.1.0/24 to clients. Specify the TFTP server and configuration file name for the clients.

   [RouterA] dhcp server ip-pool 1
   [RouterA-dhcp-pool-1] network 192.168.1.0 24
   [RouterA-dhcp-pool-1] tftp-server ip-address 192.168.1.40
   [RouterA-dhcp-pool-1] bootfile-name device.cfg
   [RouterA-dhcp-pool-market] quit
   

2. Configure the TFTP server:

   # On the TFTP server, create the configuration file device.cfg.

   #
   telnet server enable
   #
   local-user user
   password simple abcabc
   service-type telnet
   quit
   #
   user-interface vty 0 4
   authentication-mode scheme
   user-role network-admin 
   quit
   #
   interface gigabitethernet 2/1/1
   port link-mode route
   ip address dhcp-alloc
   return
   

   # Start TFTP service software. (Details not shown.)

1. Power on Router B.

2. After Router B starts up, display assigned IP addresses on Router A.

   <RouterA> display dhcp server ip-in-use
   IP address       Client identifier/    Lease expiration      Type
                    Hardware address
   192.168.1.2      0030-3030-632e-3239-  Dec 12 17:41:15 2013  Auto(C)
                    3035-2e36-3736-622d-
                    4574-6830-2f30-2f32
   

3. Telnet to 192.168.1.2 from Router A.

   <RouterA> telnet 192.168.1.2
   

4. Enter the username user and password abcabc as prompted. (Details not shown.)

   You are logged in to Router B.
