Cisco Router IPv4 Addressing (CCNA Lab 1-2)

This lab will help us better understand configuring a router’s serial and fast ethernet interfaces. This builds upon what was covered in CCNA Lab 1-1. The scenario for this lab is as follows:

You are the network administrator at Ranet, and have to config the router “Ranet-BR” via Console Terminal as below:

1. enable interface Se 0/0/0 and set IP address /Subnet Mask so that it can connect with router “Ranter-HQ” at 192.168.0.254/30
2. enable interface Se 0/1/0 and set IP address /Subnet Mask so that it can connect with router “Ranter-BR1-1” at 192.168.0.30/30
3. The Headquaters has given IP address range 192.168.0.0/27 for the network behind our router, then you have to:
3.1 enable interface Fa 0/0 and set IP address/Subnet Mask to be the last IP of this subnet that has 10 host as members.
3.2 enable interface Fa0/1 and set IP address/Subnet Mask to be the last IP of this subnet that has 5 host as members.
3.3 Set IP address/Subnet Mark of Host1 in each LAN to be the first IP of its own subnet, and set IP of gateway also

If the configuration is correct, Host1 in each subnet will be able to ping Ranet Server at 192.168.0.33.

1. enable interface Se 0/0/0 and set IP address /Subnet Mask so that it can connect with router “Ranter-HQ” at 192.168.0.254/30

After consoling into router Ranet-BR enter the global configuration command mode.

Ranet-BR>enable
Ranet-BR#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Ranet-BR(config)#

Enter the interface configuration command mode for serial interface 0/0/0 and set the IP address to 192.168.0.253 255.255.255.252 (this is the only other useable IP address in that subnet).

Ranet-BR(config)#interface serial 0/0/0
Ranet-BR(config-if)#ip address 192.168.0.253 255.255.255.252
Ranet-BR(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up

Ranet-BR(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up

 2. enable interface Se 0/1/0 and set IP address /Subnet Mask so that it can connect with router “Ranter-BR1-1” at 192.168.0.30/30interface fastethernet 0/0
ip address 192.168.0.14 255.255.255.240
no shutdown

Ranet-BR(config)#interface serial 0/1/0
Ranet-BR(config-if)#ip address 192.168.0.29 255.255.255.252
Ranet-BR(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/1/0, changed state to up

Ranet-BR(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0, changed state to up

3. The Headquaters has given IP address range 192.168.0.0/27 for the network behind our router, then you have to:

3.1 enable interface Fa 0/0 and set IP address/Subnet Mask to be the last IP of this subnet that has 10 host as members.

Ranet-BR(config)#interface fastEthernet 0/0
Ranet-BR(config-if)#ip address 192.168.0.14 255.255.255.240
Ranet-BR(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

Ranet-BR(config-if)#exit

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet 0/0, changed state to up

 3.2 enable interface Fa0/1 and set IP address/Subnet Mask to be the last IP of this subnet that has 5 host as members.

Ranet-BR(config)#interface fastEthernet 0/1
Ranet-BR(config-if)#ip address 192.168.0.22 255.255.255.248
Ranet-BR(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet 0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet 0/1, changed state to up

Ranet-BR(config-if)#exit

3.3 Set IP address/Subnet Mark of Host1 in each LAN to be the first IP of its own subnet, and set IP of gateway also.

On each Host1, open the desktop tab and click IP configuration and enter the appropriate settings.

Set the IP address of Host1 on LAN1 as 192.168.0.1, subnet mask as 255.255.255.240 and default gateway as 192.168.0.14.

Set the IP address of Host1 on LAN1 as 192.168.0.1, subnet mask as 255.255.255.240 and default gateway as 192.168.0.14.

Set the IP address of Host1 on LAN2 as 192.168.0.17, subnet mask as 255.255.255.248 and default gateway as 192.168.0.22.

Set the IP address of Host1 on LAN2 as 192.168.0.17, subnet mask as 255.255.255.248 and default gateway as 192.168.0.22.

If the configuration is correct, Host1 in each subnet will be able to ping Ranet Server at 192.168.0.33.

Execute a ping command from Host1 on each LAN. Ping 192.the Ranet Server at 168.0.33 to test network connectivity.

Ping the Ranet Server from Host1 on LAN1.

Ping the Ranet Server from Host1 on LAN1.

Ping the Ranet Server from Host1 on LAN2.

Ping the Ranet Server from Host1 on LAN2.

If you get replies from your pings than you did it! Great job completing this lab.
