S3 Openlab1 Spanning Tree

Given the network as in the diagram above, you have to complete tasks below:


1           Basic Configuration
1.      Hostnames: Assign the Routers and Switchs name as topology. For example: BR1, Sw12….

2.      Passwords & Banner Message:
a.       Console and VTY lines are password , password=’class’.
b.      Set the privileged mode password (enable secret password) to ‘cisco’.
c.       Banner contains the name of device:router1, router2. (type "#router1#"...)
d.      Set clock rate on serial interface as 64000

2           Head Quarter region
2.1         VLANs:

2.2         VTP:
VTP Domain: HeadQuarter
VTP pass: hqp@ss123
Sw31: server
Other switch: client
Note: change all switch mode to transparent when they learned all VLAN info.
2.3         STP:
STP mode: PVST+
Sw31: root bridge for all VLANs
Enable Cisco portfast on all accessLayer’switchs.         
2.4         IP address:
All End users connect to VLAN have ip address in the subNetwork: 168.79.X.0/24, where X is VLAN ID
Router subinterface is assigned ip address with 4­th octet : routerID
Ex: interface f0/1.10 of R3: 168.79.10.3
2.5         Routing
Router HeadQuarter shares routing info with other router using OSPF 1 area 0 (use network command with associated wildcard mask).
Configure routing in a stick on interface F0/1 of a router HeadQuarder.
Ex: vlan 10: f0/1.10, vlan20: f0/1.20…
3           BrandOffice1 region
3.1         VLANs:

3.2         VTP:
VTP Domain: BrandOffice1
VTP pass: br1p@ss123
Sw11: server
Other switch: client
3.3         STP:
STP mode: PVST+
Sw11: root bridge for all VLANs
Enable Cisco portfast on all switchs.     
3.4         IP address:
All End users connect to VLAN have ip address in the subNetwork: 154.0.X.0/24, where X is VLAN ID
Router subinterface is assigned ip address with 4­th octet : routerID (like 2.4)
3.5         Routing
Configure routing in a stick on interface F0/0 of the router BrandOffice1.
Ex: vlan 10: f0/0.10, vlan20: f0/0.20…
Router BrandOffice1 shares routing info with other router using OSPF 1 area 0 (use network command with associated wildcard mask).
3.6         Wireless (on AP1).
Internet port IP: 154.0.20.11
SSID: BrandOffice1
Mode: mixed
Local ip address: 10.0.1.0/24. Lan port IP: 10.0.1.1/24
Security Mode: WPA 2 Personal
-          Encryption: AES
-          Passphrase: BrandOffice1@wifi
Note: Student has to turn on the PC wirelessNIC to test the Wifi.
4           BrandOffice2 region
4.1         VLANs:





4.2         VTP:
VTP Domain: BrandOffice2
VTP pass: br2p@ss123
Sw11: server
Other switch: client
4.3         STP:
STP mode: PVST+
Sw21: root bridge for all VLANs
Enable Cisco portfast on all switchs.     
4.4         IP address:
All End users connect to VLAN have ip address in the subNetwork: 167.1.X.0/24, where X is VLAN ID
Router subinterface is assigned ip address with 4­th octet : routerID (like 2.4)
4.5         Routing
Configure routing in a stick on interface F0/0 of the router BrandOffice1.
Ex: vlan 10: f0/1.10, vlan20: f0/1.20…
Router BrandOffice1 shares routing info with other router using OSPF 1 area 0 (use network command with associated wildcard mask).
4.6         Wireless (on AP2).
Internet port IP: 167.1.20.22
SSID: BrandOffice2
Mode: mixed
Local ip address: 192.168.1.0. Lan port IP: 192.168.1.1/24
Security Mode: WPA 2 Personal
-          Encryption: AES
-          Passphrase: BrandOffice2@wifi
Note: Student has to turn on the PC wirelessNIC to test the Wifi.

5           IV. WAN Network
Each router has connection to ISP via serial interface with second ip address of the subnetwork.
-          R1: 200.200.200.4/30
-          R2: 200.200.200.0/30
-          R3: 200.200.200.8/30
All routers have default route to the ISP using static routing.
           
R1, R2, R3, TFTP and WEB server using the ip address of Subnetwork 134.23.54.0/24 connect to the cluster(R1: +1, R2: +2, R3: +3, TFTP: +10, WEB: +11).
All router and switch have to save configuration file on TFTP server
