Planning and Building an Enterprise Network

Objective

·         Plan, design, and build a large enterprise network utilizing multiple VLANs, inter-VLAN routing, and VTP domains.

Background / Preparation

A new remote site has been acquired by your company and the network needs to be built. You must plan, design, and build the network to meet company standards. The following equipment has been provided.

·         Three Cisco 2960 switches have been purchased, one for each of the three floors.

·         One Cisco 1841 router has been purchased as the Integrated Service Router (ISR).

Step 1: Connecting the network

a.    Utilize the first FastEthernet interface on the ISR router to connect to the last FastEthernet interface on the Floor 1 switch.

b.    Connect GigabitEthernet 1/1 on the Floor 1 switch to GigabitEthernet 1/1 on the Floor 2 switch.

c.    Connect GigabitEthernet 1/2 on the Floor 2 switch to GigabitEthernet 1/1 on the Floor 3 switch.

Step 2: Configure basic switch and router configurations

Utilize the following table to configure the ISR router, Floor 1, Floor 2, and Floor 3 switches.

Router    

Router>enable

Router#configure terminal

Router(config)#hostname ISR_Rtr

ISR_Rtr(config)#enable password cisco123

ISR_Rtr(config)#line vty 0 4

ISR_Rtr(config-line)#password class

ISR_Rtr(config-line)#login

ISR_Rtr(config-line)#exit

ISR_Rtr(config)#line console 0

ISR_Rtr(config-line)#password class

ISR_Rtr(config-line)#login

ISR_Rtr(config-line)#exit

Switch set the all switches

Switch>enable

Switch#configure terminal

Switch(config)#hostname Floor1_Sw

Floor1_Sw(config)#enable password cisco123

Floor1_Sw(config)#line vty 0 4

Floor1_Sw(config-line)#password class

Floor1_Sw(config-line)#login

Floor1_Sw(config-line)#exit

Floor1_Sw(config)#line console 0

Floor1_Sw(config-line)#password class

Floor1_Sw(config-line)#login

Floor1_Sw(config-line)#exit

Do same to switch 2 and switch 3.

Step 3: Configure the interfaces connecting the router and switches

a.    Set the interfaces connecting the Floor 1, Floor 2, and Floor 3 switches as trunk ports.

b.    Set the interface on the Floor 1 switch connecting to the ISR router as a trunk port.

c.    Enable the interface on the ISR router connecting to the Floor 1 switch.

d.    Create and configure three sub-interfaces on the ISR routers FastEthernet 0/0 interface. Use the following table.

1.     Set the encapsulation for each sub-interface

2.     Set the IP address for each sub-interface.

a.    Floor1_Sw(config)#interface gigabitEthernet 1/1

Floor1_Sw(config-if)#switchport mode trunk

Floor1_Sw(config-if)#exit

Do same to switch 2 and switch 3.

b.    Floor1_Sw(config)#interface fastEthernet 0/24

Floor1_Sw(config-if)#switchport mode trunk

c.    ISR_Rtr(config)#interface fastEthernet 0/0

ISR_Rtr(config-if)#no ip address

ISR_Rtr(config-if)#no shutdown

ISR_Rtr(config-subif)#exit

d.     ISR_Rtr(config)#interface fastEthernet 0/0.20

ISR_Rtr(config-subif)#encapsulation dot1q 20

ISR_Rtr(config-subif)#ip address 192.168.20.1 255.255.255.0

ISR_Rtr(config-subif)#exit

Step 4: Configure a VTP Domain

Utilize the following table to configure the Floor 1, Floor 2, and Floor 3 switches.

a.     Floor 2 dan 3

Floor2_Sw(config)#vtp domain SiteX

Changing VTP domain name from NULL to SiteX

Floor2_Sw(config)#vtp mode client

Setting device to VTP CLIENT mode.

Floor2_Sw(config)#vtp password ciscoVTP

Setting device VLAN database password to ciscoVTP

Floor2_Sw(config)#exit

b.     Floor 1

Floor1_Sw(config)#vtp domain SiteX

Domain name already set to SiteX.

Floor1_Sw(config)#vtp mode server

Device mode already VTP SERVER.

Floor1_Sw(config)#vtp password ciscoVTP

Setting device VLAN database password to ciscoVTP

Floor1_Sw(config)#exit

Step 5: Configure VLANs

Utilize the following table to configure the VLANs from the VTP server.

-      Floor1_Sw(config)#vlan 20

-      Floor1_Sw(config-vlan)#name Admin

-      Floor1_Sw(config-vlan)#exit

-      Floor1_Sw(config)#vlan 25

-      Floor1_Sw(config-vlan)#name Management

-      Floor1_Sw(config-vlan)#exit

-      Floor1_Sw(config)#vlan 30

-      Floor1_Sw(config-vlan)#name Finance

-      Floor1_Sw(config-vlan)#exit

Step 6: Add switch ports to the appropriate VLAN

a.    Configure the Floor 1 switch so that FastEthernet 0/1 is on VLAN 20.

b.    Configure the Floor 2 switch so that FastEthernet 0/1 is on VLAN 25.

c.    Configure the Floor 3 switch so that FastEthernet 0/1 is on VLAN 30.

Floor1_Sw :

-       Floor1_Sw(config)#interface fastEthernet 0/1

-      Floor1_Sw(config-if)#switchport mode access

-      Floor1_Sw(config-if)#switchport access vlan 20

-      Floor1_Sw(config-if)#exit

Floor2_Sw :

-      Floor2_Sw(config)#interface fastEthernet 0/1

-      Floor2_Sw(config-if)#switchport mode access

-      Floor2_Sw(config-if)#switchport access vlan 25

-      Floor2_Sw(config-if)#exit

Floor3_Sw :

-      Floor3_Sw(config)#interface fastEthernet 0/1

-      Floor3_Sw(config-if)#switchport mode access

-      Floor3_Sw(config-if)#switchport access vlan 30

-      Floor3_Sw(config-if)#exit

Step 7: Connect and configure client workstations

1. Connect PC0 to the Floor 1 switch via FastEthernet 0/1.
2. Connect PC1 to the Floor 2 switch via FastEthernet 0/1.
3. Connect PC2 to the Floor 3 switch via FastEthernet 0/1.

Step 8: Verify connectivity

1. Using the Command Prompt, ping PC1 and PC2 from PC0.
2. Using the Command Prompt, ping PC0 and PC2 from PC1.
3. Using the Command Prompt, ping PC0 and PC1 from PC2.
