QUESTION 39
SIMULATION
CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP.
CCNA.com has recently added the ENG router. Currently, the ENG router does not have connectivity to the ISP router. All over interconnectivity and Internet access for the existing locations of the company are working properly.
The task is to identify the fault(s) and correct the router configuration(s) to provide full connectivity between the routers.
Access to the router CLI can be gained by clicking on the appropriate host.
All passwords on all routers are cisco.
IP addresses are listed in the chart below.
MGT
Fa0/0 – 192.168.77.33
S1/0 – 198.0.18.6
S0/0 – 192.168.27.9

QUESTION 40
SIMULATION
The following have already been configured on the router:
The basic router configuration
The appropriate interfaces have been configured for NAT inside and NAT outside.
The appropriate static routes have also been configured (since the company will be a stub network, no routing protocol will be required)
All passwords have been temporarily set to “cisco”.
The task is to complete the NAT configuration using all IP addresses assigned by the ISP to provide Internet access for the hosts in the Weaver LAN. Functionality can be tested by clicking on the host provided for testing.
Configuration information:
router name – Weaver
inside global addresses – 198.18.184.105 – 198.18.184.110/29
inside local addresses – 192.168.100.17 – 192.168.100.30/28
number of inside hosts – 14A network associate is configuring a router for the weaver company to provide internet access. The ISP has provided the company six public IP addresses of 198.18.184.105 198.18.184.110. The company has 14 hosts that need to access
the internet simultaneously. The hosts in the company LAN have been assigned private space addresses in the range of 192.168.100.17 – 192.168.100.30.
Correct Answer: Explanation
Explanation
Explanation/Reference:
The company has 14 hosts that need to access the internet simultaneously but we just have 6 public IP addresses from 198.18.184.105 to 198.18.184.110/29.
Therefore we have to use NAT overload (or PAT)
Double click on the Weaver router to open it
Router>enable
Router#configure terminal
First you should change the router’s name to Weaver
Router(config)#hostname Weaver
Create a NAT pool of global addresses to be allocated with their netmask.
Weaver(config)#ip nat pool mypool 198.18.184.105 198.18.184.110 netmask 255.255.255.248
Create a standard access control list that permits the addresses that are to be translated.
Weaver(config)#access-list 1 permit 192.168.100.16 0.0.0.15
Establish dynamic source translation, specifying the access list that was defined in the prior step.
Weaver(config)#ip nat inside source list 1 pool mypool overload
This command translates all source addresses that pass access list 1, which means a source address from 192.168.100.17 to 192.168.100.30, into an address from the pool named mypool (the pool contains addresses from 198.18.184.105
to 198.18.184.110).
Overload keyword allows to map multiple IP addresses to a single registered IP address (many-to-one) by using different ports.
The question said that appropriate interfaces have been configured for NAT inside and NAT outside statements.
This is how to configure the NAT inside and NAT outside, just for your understanding:
Weaver(config)#interface fa0/0
Weaver(config-if)#ip nat inside
Weaver(config-if)#exit
Weaver(config)#interface s0/0
Weaver(config-if)#ip nat outside
Weaver(config-if)#end
Finally, we should save all your work with the following command:
Weaver#copy running-config startup-config
Check your configuration by going to „Host for testing” and type:
C :\>ping 192.0.2.114
The ping should work well and you will be replied from 192.0.2.114
