Instructions

All configurations must be performed through a direct terminal connection to the device consoles.

Step 1: Determine the Addresses to Assign

Determine the IP addresses that you will use for the required interfaces on the three routers and two switches. Use the information in the Addressing Table and follow the guidelines below:

  • Assign the first IP addresses in the networks that are provided in the Addressing Table to the LAN interfaces.
  • Assign the first address in the Central subnet to the interface that is connected to the Internet.
  • Assign any valid host address in the networks that are provided in the Addressing Table to the serial interfaces.
  • The host PCs will receive IP addresses over DHCP.

Step 2: Configure Police

  • Configure Police with the following:
  • Configure the router host name: PoliceDept  

Router(config)# hostname PoliceDept

  • Prevent the router from attempting to resolve command line entries to IP addresses.

PoliceDept(config)# no ip domain-lookup 

  • Protect privileged EXEC mode from unauthorized access with the MD5 encrypted password.

PoliceDept(config)# enable secret [password]

  • Prevent device status messages from interrupting command line entries at the device console.

PoliceDept(config)# line con 0

PoliceDept(config-line)# logging synchronous

  • Secure the router console and terminal lines.

PoliceDept(config)# line console 0

password [password]

login

PoliceDept(config)# line vty 0 4

password [password]

login

  • Prevent all passwords from being viewed in clear text in the device configuration file.

PoliceDept(config)# service password-encryption

  • Configure a message-of-the-day banner.

PoliceDept(config)# banner motd “message-of-the-day”

Step 3: Configure the Router Physical Interfaces

Configure the interfaces of the routers for full connectivity with the following:

  • IP addresses as shown in the addressing table.
  • Describe the operational Police serial interface. The Police Ethernet interfaces will be configured at the end of this assessment.
  • DCE settings where appropriate. Use a rate of 128000.

PoliceDept(config)# interface Serial0/0/0
PoliceDept(config-if)#bandwidth 128
PoliceDept(config-if)#ip address 192.168.10.105 255.255.255.252
PoliceDept(config-if)#description Police and Central
PoliceDept(config-if)#clock rate 128000
PoliceDept(config-if)#no shutdown

Central(config)# interface Serial0/0/0
Central(config-if)#bandwidth 128
Central(config-if)#ip address 192.168.10.106 255.255.255.252
Central(config-if)#no shutdown

Central(config)# interface Serial0/0/1
Central(config-if)#bandwidth 128
Central(config-if)#ip address 192.168.10.114 255.255.255.252
Central(config-if)#clock rate 128000
Central(config-if)#no shutdown

Central(config)# interface g0/0
Central(config-if)#ip address 192.168.18.41 255.255.255.248
Central(config-if)#no shutdown

Central(config)# interface Serial0/1/0
Central(config-if)#ip address 198.51.100.1 255.255.255.240
Central(config-if)#no shutdown

Fire(config)# interface Serial0/0/1
Fire(config-if)#bandwidth 128
Fire(config-if)#ip address 198.51.100.1 255.255.255.240
Fire(config-if)#no shutdown

Step 4: Configure static and default routing

Configure the following static routes:

  • Manually configure default routes to the Internet. Use the exit interface argument. All hosts on the internal LANs and School Network networks should be able to reach the Internet.

PoliceDept(config)#ip route 0.0.0.0 0.0.0.0 s0/0/0

Central(config)#ip route 0.0.0.0 0.0.0.0 s0/1/0

Fire(config)#ip route 0.0.0.0 0.0.0.0 s0/0/1

  • It has been decided to use static routes to reach the branch networks that are connected to Fire. Use a single summary to represent the branch networks in the most efficient way possible. Configure the summary static route onCentral and Fire using the exit interface argument.

Central(config)#ip route 192.168.200.0 255.255.252.0 s0/0/1

Fire(config)#ip route 192.168.200.0 255.255.252.0 s0/0/0

Step 5: Configure OSPF Routing

Configure single-area OSPFv2 to route between all internal networks. The branch networks are not routed with OSPFv2.

  • Use a process ID of 10.The routers should be configured in area 0.
  • Use the correct inverse masks for all network statements. Do not use quad zero masks (0.0.0.0).

Step 6: Customize single-area OSPFv2

Customize single-area OSPFv2 by performing the following configuration tasks:

a. Set the bandwidth of the serial interfaces to 128 kb/s.

b. Configure OSPF router IDs as follows:

  • Police: 1.1.1.1
  • Central: 2.2.2.2
  • Fire: 3.3.3.3

c. Configure the OSPF cost of the link between Police and Central to 7500.

d. Prevent routing updates from being sent out of any of the LAN interfaces that are routed with OSPFv2. Do not use the default keyword in the commands you use to do this.

Configuration step 5 and step 6

PoliceDept(config)#router ospf 10

PoliceDept(config-router)#router-id 1.1.1.1

PoliceDept(config-router)#network 192.168.10.104 0.0.0.3 area 0

Police-SW2(config-if-range)#shutdown

Step 8: Configure DHCP

Police should be configured as a DHCP server that provides addressing to the hosts attached to Police-SW1 and Police-SW2. The requirements are as follows:

  • Use VLAN45 and VLAN47 as the pool names. Note that the pool names must match the names given here exactly, all capital letters and exact spelling.
  • Addresses .1 to .20 should be reserved for static assignment from each pool.
  • The first address in each network will be assigned to the router interface attached to the networks as shown in the addressing table.
  • Use a DNS server address of 192.168.18.100. This server has not yet been added to the network, but the address must be configured.
  • Ensure that hosts in each LAN are able to communicate with hosts on remote networks.

PoliceDept(config)#ip dhcp excluded-address 192.168.45.1 192.168.45.20
PoliceDept(config)#ip dhcp excluded-address 192.168.47.1 192.168.47.20

PoliceDept(config)#ip dhcp pool VLAN45
PoliceDept(dhcp-config)#network 192.168.45.0 255.255.255.0
PoliceDept(dhcp-config)#default-router 192.168.45.1
PoliceDept(dhcp-config)#dns-server 192.168.18.100

PoliceDept(config)#ip dhcp pool VLAN47
PoliceDept(dhcp-config)#network 192.168.47.0 255.255.255.0
PoliceDept(dhcp-config)#default-router 192.168.47.1
PoliceDept(dhcp-config)#dns-server 192.168.18.100

*Set Clients to DHCP*

PC1, PC2, PC3, PC4

Step 9: Configure NAT

Configure NAT to translate internal private addresses into public addresses for the Internet. The requirements are:

a. Configure static NAT to the Town Server.

  • Translate the internal address of the server to the address 198.51.100.14.
  • Configure the correct interfaces to perform this NAT translation.

Central(config)#ip nat inside source static 192.168.18.46 198.51.100.14
Central(config)#interface g0/0
Central(config-if)#ip nat inside

Central(config)#interface s0/1/0
Central(config-if)#ip nat outside

b.Configure dynamic NAT (not NAT with overload, or PAT).

  • Use the addresses remaining in the public address subnet of 198.51.100.0/28. The first two addresses in the subnet have already been assigned to the Central and ISP serial interfaces. Also, another address has already been used in the static mapping in the step above.
  • Use a pool name of INTERNET. Note that the pool name must match this name exactly, in spelling and capitalization.
  • Hosts on each of the internal LANs shown in the topology and on all of the branch networks should be permitted to use the NAT addresses to access the Internet.
  • Use a source list number of 1.
  • Your source list should consist of three entries, one each for the LANs and one for the branch networks.

permit 192.168.47.0 0.0.0.255
permit 192.168.200.0 0.0.3.255

Step 10: Configure Access Control Lists

You will configure two access control lists to limit device access on Central. You should use the any and host keywords in the ACL statements as required.  The ACL requirements are:

a. Restrict access to the vty lines on Central:

  • Create a named standard ACL using the name MANAGE. Be sure that you use this name exactly as it appears in these instructions (case and spelling).
  • Allow only the  NetAdmin Host to access the vty lines of Central.
  • No other Internet hosts (including Internet hosts not visible in the topology) should be able to access the vty lines of Central.
  • Your solution should consist of a single ACL statement.

b.Allow outside access to the Town Server while controlling other traffic from the outside. Create the ACL as directed below:

  • Use access list number 101.
  • First, allow NetAdmin Host full access to all network hosts and devices.
  • Then, allow outside hosts to access the Town Server over HTTP only.
  • Allow traffic that is in response to data requests from the internal and School Network hosts to enter the network.
  • Add a statement so that counts of all denied traffic will be shown in the show access-lists command output.
  • Your ACL should have only four statements.

Your ACL should be placed in the most efficient location possible to conserve network bandwidth and device processing resources.

Step 11: Configure Router-on-a-Stick Inter-VLAN Routing.

Configure Police to provide routing between the VLANs configured on the switches. As follows:

  • Use the VLAN numbers for the required interface numbers.
  • Use the first addresses in the VLAN networks for the interfaces.

PoliceDept(config)# interface g0/0
PoliceDept(config-if)#no sh

PoliceDept(config)# interface g0/0.45
PoliceDept(config-subif)#encapsulation dot1Q 45
PoliceDept(config-subif)#ip address 192.168.45.1 255.255.255.0

PoliceDept(config)# interface g0/0.47
PoliceDept(config-subif)#encapsulation dot1Q 47
PoliceDept(config-subif)#ip address 192.168.47.1 255.255.255.0

PoliceDept(config)# interface g0/0.101
PoliceDept(config-subif)#encapsulation dot1Q 101
PoliceDept(config-subif)#ip address 192.168.101.1 255.255.255.0

Step 12: Test and Troubleshoot Connectivity.

Ensure that the hosts attached to the VLANs can reach hosts on the School Network and the Internet.

Use DHCP to assign addresses from the pool of Class B addresses.

Assign static internal addresses and public external addresses to each of the servers.*

 

7. What is a disadvantage of NAT?

There is no end-to-end addressing.*

The router does not need to alter the checksum of the IPv4 packets.​

The internal hosts have to use a single public IPv4 address for external communication.

The costs of readdressing hosts can be significant for a publicly addressed network.​

 

8. Refer to the exhibit. What has to be done in order to complete the static NAT configuration on R1?

R1 should be configured with the command ip nat inside source static 209.165.200.1 192.168.11.11.

R1 should be configured with the command ip nat inside source static 209.165.200.200 192.168.11.11.

Interface S0/0/0 should be configured with the command ip nat outside.*

Interface Fa0/0 should be configured with the command no ip nat inside.

 

9. Refer to the exhibit. R1 is configured for NAT as displayed. What is wrong with the configuration?

Access-list 1 is misconfigured.

NAT-POOL2 is not bound to ACL 1.*

Interface Fa0/0 should be identified as an outside NAT interface.

The NAT pool is incorrect.

 

10. Which statement accurately describes dynamic NAT?

It always maps a private IP address to a public IP address.

Port forwarding allows users to reach servers on the Internet that are not using standard port numbers.

Port forwarding allows an internal user to reach a service on a public IPv4 address that is located outside a LAN.

Port forwarding allows for translating inside local IP addresses to outside local addresses.

 

19. What is a characteristic of unique local addresses?

They allow sites to be combined without creating any address conflicts.*

They are designed to improve the security of IPv6 networks.

Their implementation depends on ISPs providing the service.

They are defined in RFC 3927.

 

20. Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?

dynamic NAT with a pool of two public IP addresses

PAT using an external interface*

static NAT with one entry

static NAT with a NAT pool

Based on the configuration and the output shown, what can be determined about the NAT status within the organization?

NAT is working.

Static NAT is working, but dynamic NAT is not.

Dynamic NAT is working, but static NAT is not.

Not enough information is given to determine if both static and dynamic NAT are working.*

 

22. Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254 across a router R1 that is running dynamic NAT. (Not all option are used.)


Place the options in the following order:
– not scored –
step 5 => R1 replaces the address 192.168.10.10 with a translated inside global address.
step 2 => R1 checks the NAT configuration to determine if this packet should be translated.
step 4 => R1 selects an available global address from the dynamic address pool.
step 1 => The cost sends packets that request a connection to the server at the address 209.165.200.254
step 3 => If there is no translation entry for this IP address, R1 determines that the source address 192.168.10.10 must be translated.

 

23.

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

What problem is causing PC-A to be unable to communicate with the Internet?

The static route should not reference the interface, but the outside address instead.

This router should be configured to use static NAT instead of PAT.

The ip nat inside source command refers to the wrong interface.

The access list used in the NAT process is referencing the wrong subnet.

The NAT interfaces are not correctly assigned.*
