Objectives
• Configure the device host name for a router.
• Configure console, privileged mode and virtual terminal passwords.
• Configure Ethernet and Serial interfaces.
• Verify connectivity between hosts and routers.

Background / Preparation
Set up a network similar to the one in the topology diagram. Any router that meets the interface requirements displayed in that diagram – such as 800, 1600, 1700, 1800, 2500, and 2600 routers, or a combination – may be used. Refer to the Router Interface Summary table at the end of the lab to correctly determine the interface identifiers to be used based, on the equipment in the lab. Depending on the router model, output may vary somewhat from that shown in this lab. The steps in this lab are intended to be executed on each router unless you are specifically instructed otherwise.

Any router that meets the interface requirements displayed in that diagram – such as 800, 1600, 1700, 1800, 2500, and 2600 routers, or a combination – may be used. Refer to the Router Interface Summary table at the end of the lab to correctly determine the interface identifiers to be used based, on the equipment in the lab. Depending on the router model, output may vary somewhat from that shown in this lab. The steps in this lab are intended to be executed on each router unless you are specifically instructed otherwise.
The following resources are required:
• Two routers, each with an Ethernet and Serial interface. These should be non-SDM routers, if possible, since the required SDM startup configuration is deleted when the startup-config is erased.
• Two Windows XP computers
• Straight-through category 5 Ethernet cable (PC1 to switch)
• Crossover category 5 Ethernet cable (PC2 to router R2)
• Null Serial cable
• Console cable(s) (from PCs 1 and 2 to routers R1 and R2)
• Access to the PC command prompt
• Access to PC network TCP/IP configuration

Step 1 : Configure Host IP Setting
a. Make sure that the PCs are connected according to the topology diagram
b. Configure static IP addresses on them sa follows
PC attached to R1 switch:
IP address: 172.16.0.2
Subnet mask: 255.255.0.0
Default gateway: 172.16.0.1
PC attached to R2 directly:
IP address: 172.18.0.2
Subnet mask: 255.255.0.0
Default gateway: 172.18.0.1

Step 2: Log In To Each Router And Configure A Host Name an Password
a. Configure a host name for each of the two routers. Repeats this process for router R2
Router> enable
Router#configure terminal
Router(config)#hostname R1
b. Configure a console password and enable login for each of the two routers. Repeats this process for router R2
R1(config)# line console 0
R1(config-line)#password cisco
R1(config-line)#login R1(config-line)#exit
R1(config)#
c. Configure the password on the virtual terminal lines for each of the two routers. Repeats this process for router R2
R1(config)# line vty 0 4
R1(config-line)#password cisco
R1(config-line)#login R1(config-line)#exit
R1(config)#
d. Configure the enable and and enable secret password for each of the two routers.

Step 3: Show The Router Running Configuration
a. From the privteged EXEC prompt issue the show running-config command this command can be abbreviated as shrun
b. Is there an encrypted password? Tidak
c. Are there any other password? Ya
d. Are any of the other password encrypted? Tidak

Step 4: Configure The Serial Interface On R1
From global configuration mode, configure serial interface Serial 0 on Router R1. Refer to the Router Interface Summary chart at the end of the lab for the proper designation of the serial interface on the router that you are using for this lab.
R1(config)#interface serial 0/0
R1(config-if)#ip address 172.17.0.1 255.255.0.0
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
R1(config-if)#exit R1(config)#exit

Step 5: Display Information About The Serial Interface On R1
a. Enter the show interface command on R1. Refer to the router interface summary chart.
b. List at least three details discovered by issuing this command.
Serial 0/0 is: down
Line protocol is: down
Internet address is: 172.17.0.1/16
Encapsulation: HDLC
To what OSI layer is the encapsulation referring?
c. If the serial interface was configured, why did the show interface serial 0/0 say that the interface is down?

Step 6: Configure The Serial Interface On R2
From global configuration mode, configure serial interface Serial 0 on Router R1. Refer to the Router Interface Summary chart at the end of the lab for the proper designation of the serial interface on the router that you are using for this lab.
R2(config)#interface serial 0/0
R2(config-if)#ip address 172.17.0.2 255.255.0.0
R2(config-if)#clock rate 64000
R2(config-if)#no shutdown
R2(config-if)#exit R2(config)#exit

Step 7: Display Information About The Serial Interface On R2
a. Enter the show interface command on R1. Refer to the router interface summary cahrt.
b. List at least three details discovered by issuing this command
Serial 0 is: up
Line protocol is: up
Internal address is: 172.17.0.2/16
Enscapsulation: HDLC
To what OSI layer is the Encapsulation referring?

Step 8: Verify That The Serial Conection Is Functioning
a. Use the ping command to test connectivity to the other router. From R1 ping the The R2router serial interface.
Does the ping work?
b. From R2 ping the R1 router serial interface
Does the ping work?
c. If the answer is no for either question. Troubleshoot the router configuration to find the error. Then ping the interface again until the answer to both question is yes.

Step 13: Save The Configuration On Both Routers
Save the running configuration to the startup configuration at the privileged EXEC mode.
R1#copy running-config startup-config
R2#copy running-config startup-config

Step 14: Check The Overall Router Configurations
Issue the show running-config command from the privileged EXEC mode on both routes and verify all of the configuration commands you have entered so far. Note that this command can be abbreviated as sh run.
