LAB 4-9: Dynamic Host Configuration Protocol (DHCP)

You are the network administrator at Ranet, and have to configure the router Ranet-GW to connect
between LAN and Internet, and to do as DHCP server for LAN as below:
(via Console)
1. Enable and set IP address on LAN interface to be the first IP of the subnet 10.0.0.128/28
2. Enable and set IP address on serial interface to be the last IP of the subnet 77.8.210.0/30
3. Set the default route to let the connection out to the internet.
4. Configure to let this router translate between the addresses in this LAN and the addresses
ISP gave us (19.5.39.129 – 19.5.39.130)

Remark: use ACL no.1 and pool named“Ranet” only!

5. Configure to let this router do as DHCP server for the hosts in LAN. You have to supply all
information that is necessary for hosts to connect to the internet, and do not forget to
exclude addresses of the gateway and the switch.

Remark: use pool named “Ranet” also!

If everything is correct, all hosts have to be able to open website http://www.ranet.co.th

Solution:

Ranet-GW config
(copy & paste these command below to Ranet-GW router.)

LAB 4-8: Virtual Private Network (VPN) – IPsec (Site-to-Site)

You are the Network Administrator at Ranet Branch Office, and have to newly configure the Ranet-Br router to let your own host connect to the internet and connect to the hosts in Headquarter (192.168.0.0/24) via Site-to-Site IPsec VPN as below:
(configure via console terminal for Ranet-BR router)

1. Enable LAN interface on Ranet-BR and set IP address to be the first assignable IP of 192.168.1.0/28 network.

2. Enable WAN interface on Ranet-BR and set IP address to be the last assignable IP of 202.170.100.28/30 network.

3. Set IP address on Host-BR to be the last assignable IP of 192.169.1.0/28 network, and set IP of Gateway and DNS server (202.170.100.54) also.

4. Config the route and NAT on Ranet-BR to let the Hosts in LAN connect to the internet (do not forget to exclude the VPN traffic).
(for NAT, use access-list no.100 and pool name “Ranet” that contain the global IP received from ISP as 202.170.100.9 – 202.170.100.14)

5. Config the Site-to-Site IPsec VPN by using the properties as below:

- For IKE phase I:- Policy Priority 101; Encryption Alg. AES-128 bit; Hash Alg. Secure HAsh standard; Authen method. Pre-Shared Key; Diffie-Hellman group #5 and lifetime at 86,400 sec. Use “ranetvpnpass” as key. Please note that IP address of WAN interface of Ranet-HQ is 202.170.100.130.
- For IKE phase II: Use Transform-set name “Ranet” and ESP transform using AES with HMAC-SHA as authentication Alg.
- Use crypto map name “Site-to-Site” with sequence no.101 and access-list no.101 to be the VPN traffic.

If everything is correct, Host-BR should be able to open website www.ranet.co.th, and test ping with Server-HQ 192.168.0.7 in Headquarter network.

You are the network administrator at Ranet,and would like to enable Port-Security on the access ports of Ranet-SW to prevent the use of another switch connected that let multiple hosts connect through the same port at the same time, and to prevent the unauthorized host connect via some port.

So all you have to do are: (Config via Console)

1. Enable Port-Security on all access ports (except Gig1/1, Gig1/2), and set parameter to allow only 1 MAC Address per port and the action when violation happened is shutdown port.

2. On port Fa0/1, now there is the authorized host connected (Host1), set the allow MAC Address on this port by “SecureSticky” method.

3. On port Fa0/3, now there is the unauthorized host connected (Rogue3),set the allow MAC Address to be 0030.F295.15C6.

If everything is correct, you will see ports Fa0/2 and Fa0/3 change status to down (err-disabled) when there is the attempt to connect from unauthorized hosts, and Host1 will not be able to connect with the unauthorized hosts (192.168.0.58 – 192.168.0.60) .

You are the network administrator at Ranet, and have to config the routers both Ranet-HQ and Ranet-BR to make the connection throughout Ranet network and with the Internet. So all you have to do are:
(Config via console of each router.)

1. Enable and set IP address on LAN interface of each router to be the first assignable IP of each subnet.

2. Enable serial interface on each router and set IP address on each interface as:
- s0/0/0 on Ranet-BR: first IP of 98.83.165.72/30
- s0/0/0 on Ranet-HQ: last IP of 98.83.165.72/30
- s0/1/0 on Ranet-HQ: last IP of 52.9.236.20/30

all serial interface use HDLC as encapsulation protocol and do not forget to set clock rate at 64 kbps on Ranet-BR side.

3. Set RIPv2 as routing protocol on each router to let Host1 connect to Host2.

4. Set default route on each router to let both Host1 and Host2 be able to connect to the Online Server        (55.8.92.3) in the internet.

LAB 3-4: Frame Relay – Point-to-Point (Subinterface)

You are the network administrator at Ranet Headquater, and have to configure the router “Ranet-HQ” to let Host1 connect with Host2, Host3 and Host4 as below:
(Use console to config this router.)

1. Enable and set IP address on LAN interface to be the first IP of this subnet.

2. Enable serial interface, and create subinterface with Frame-Relay setting as below:

- s0/0/0.2 for connect with Ranet-BR2, via DLCI 902
- s0/0/0.3 for connect with Ranet-BR3, via DLCI 903
- s0/0/0.4 for connect with Ranet-BR4, via DLCI 904

All subinterfaces use CISCO standard for both encapsulation and LMI, and set IP address to use the first IP in each subnet.

If everything is correct, Host1 should be able to connect
with Host2, Host3, and Host4.

3. Enable and set IP address on interface s0/0/0 on Ranet-BR2 to be the last assignable IP in the same network.
Don’t forget to set clock rate at 64 kbps due to this is the DCE.

4. Set encapsulation on this link to be PPP and use username and password as:
user: ranetpapuser
pass: ranetpappass
by using PAP as authentication protocol

If everything is done, Host1 has to be able to
connect with Host2.

LAB 2-2: Virtual Trunking Protocol (VTP) 


You are the Network Administration at Ranet, and have to config to let Ranet-SW3 seperate VLAN
according to the VLAN database from Ranet-SW1 via VTP (use Console for each switch) as below:

1. Gather information about VTP configuration in Ranet-SW1 by using "show" command in
USER mode only. (You do not have right to config anything on this switch.)

2. On switch Ranet-SW2, you have to config to let the VTP information send from Ranet-SW1
via itself to Ranet-SW3 without any change in VLAN database of Ranet-SW2

3. On switch Ranet-SW3, you have to config to receive VTP information from Ranet-SW1 and
use the received VLAN database to set members of each VLAN as:
VLAN 10: Fa0/1
VLAN 20: Fa0/2

LAB 2-1: InterVLAN Routing 

You are the Network Administrator at Ranet, and have to config both switch "Ranet-SW" and router 
"Ranet-GW" via its console terminal as below: 

1. Set Ranet-SW to seperate VLAN to be VLAN 10 and VLAN 20 and set its member as: 
VLAN 10: Fa0/1, Fa0/2 
VLAN 20: Fa0/3, Fa0/4 

2. Enable feature "Portfast" on all access ports. 

3. Set both Ranet-SW and Ranet-GW to route between VLAN 10 and VLAN 20: 

- Use interface Fa0/0.1 and Fa0/0.2 on Ranet-GW as sub-interface for VLAN 10 and 
VLAN 20 respectively.
- Please note that all hosts in each VLAN set IP Default Gateway to be the last IP of its 
own subnet. 

If everything is correct, All hosts will be able to connect with each other.

LAB 1-2: IPv4 Addressing

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

1. enable interface Se0/0/0 and set IP address
/Subnet Mask that can connect with router
“Ranter-HQ” at 192.168.0.254/30

2. enable interface Se0/1/0 and set IP address
/Subnet Mask that can connect with router
“Ranter-BR1-1″ at 192.168.0.30/30

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

3.1 enable interface Fa0/0 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
must be able to ping to Ranet Server at 192.168.0.33

============= The End ===================

Solution:


192.168.0.0/27
*10 host:
int fa0/0 : 192.168.0.0/28  --- use last ip
*5 host:
int fa0/1 : 192.168.0.16/29 -- use last ip
------------------------------
int se0/0/0 : 192.168.0.254/30 -- use first ip
int se0/1/0: 192.168.0.30/30 -- use first ip
