Your employer has installed two new Cisco routers in the network. Figure 3-5 shows the network layout. Your task is to configure the routers such that HostA can telnet into them to configure it further. Ensure correct hostnames and IP addresses are assigned. All passwords should be set to mypass123. When configuration is complete, save the configuration and back it up to the TFTP server running on HostA.

Solution

1. Connect to the console port of RouterA and when prompted enter no to exit out of setup mode. Press Enter to go to the User exec mode.

2. Enter the privileged exec mode using the command enable and then configure the hostname and enable secret as shown below:

Router#config terminal

Router(config)#hostname RouterA

RouterA(config)#enable secret mypass123 

3. Configure the IP address on the interface as shown below:

RouterA(config)#interface fa0/0

RouterA(config-if)#ip address 192.168.1.1 255.255.255.0

RouterA(config-if)#exit

4. Configure a password and enable login on line vty as shown below:

RouterA(config)#line vty 0 4

RouterA(config-line)#password mypass123

RouterA(config-line)#login

RouterA(config-line)#exit 

5. Save the config and then copy it to the TFTP server as shown below:

RouterA(config)#exit

RouterA#copy run start

Destination filename [startup-config]?

Building configuration…

[OK]

RouterA#copy run tftp:

Address or name of remote host []? 192.168.1.10

Destination filename [routera-confg]? [enter]

!!

763 bytes copied in 0.712 secs (1071 bytes/sec) 

6. Repeat steps 1-5 on RouterB. The configuration steps are given below:

Router#config terminal

Router(config)#hostname RouterB

RouterB(config)#enable secret mypass123

RouterB(config)#interface fa0/0

RouterB(config-if)#ip address 192.168.1.2 255.255.255.0

RouterB(config-if)#exit

RouterB(config)#line vty 0 4

RouterB(config-line)#password mypass123

RouterB(config-line)#login

RouterB(config-line)#exit

RouterB(config)#exit

RouterB#copy run start

Destination filename [startup-config]?

Building configuration…

[OK]

RouterB#copy run tftp:

Address or name of remote host []? 192.168.1.10

Destination filename [routerb-confg]? [enter]

!!

763 bytes copied in 0.712 secs (1071 bytes/sec)
