Automatic configuration using HTTP server and Tcl script

As shown in Figure 51, Router B does not have a configuration file.

Configure the servers so Router B can obtain a Tcl script 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.

   [RouterA] dhcp server ip-pool 1
   [RouterA-dhcp-pool-1] network 192.168.1.0 24
   

   # Specify the URL of the script file for the clients.

   [RouterA-dhcp-pool-1] bootfile-name http://192.168.1.40/device.tcl
   

2. Configure the HTTP server:

   # Create the configuration file device.tcl on the HTTP server.

   return
   system-view
   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 1/0/1
   port link-mode route
   ip address dhcp-alloc
   return
   

   # Start HTTP service software and enable HTTP service. (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-  May 12 17:41:15 2016  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.
