Lab Objective:
The objective of this lab exercise is for you to learn and understand how to configure Port Address Translation using Cisco SDM.
Lab Purpose:
Understanding Cisco SDM is a fundamental skill. SDM is a web-based application that can be used to configure routers as well as troubleshoot internetworks. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure Port Address Translation using SDM.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 5/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes
| IMPORTANT NOTE:
In order to use SDM, you must have an SDM-capable router. The following routers support SDM:
The objective of this lab exercise is to familiarize your with the SDM GUI and how to navigate through it. As long as you have one of the platforms listed above, the configuration tasks and GUI navigation will be the same. These lab exercises are based on a Cisco 3640 router with two 10Mbps Ethernet interfaces and two Serial interfaces, but can be completed on any one of the above routers with similar interfaces. Substitute the interfaces in these lab exercises with the ones you have on your router. |
Lab Topology:
Please use the following topology to complete this lab.
Task 1:
Configure the hostname on Sw1 as illustrated in the topology.
Task 2:
Configure VLAN 25 on Sw1 and assign it the name SDM_VLAN. Next, configure the E0/0 interface of SDM-1 with the IP address of 10.1.1.2/24. Ensure that the PC has the IP address 10.1.1.1/24 configured on the correct NIC. Assign ports FastEthernet0/2 and FastEthernet0/3 to VLAN 25. Configure an IP address of 10.1.1.254 on interface VLAN 25 on Sw1.
Task 3:
Using the CLI configure the S0/0 interface of R2 with the IP address specified in the topology. Enable this interface and provide clocking to SDM-1 at 768Kbps.
Task 4:
Using SDM, configure the S0/0 interface of SDM-1 with the IP address specified in the topology. Ping from R2 to SDM-1 and verify that this works. Try to ping and Telnet from Sw1 to R2. At this point, neither will work because there is no route to the 10.1.1.0/24 subnet present on R2.
Task 5:
Using SDM, configure the S0/0 interface of SDM-1 as the NAT outside interface and the E0/0 interface as the NAT inside interface. In addition, configure PAT for the 10.1.1.0/24 subnet to the Serial0/0 interface of SDM-1.
Task 6:
To test your configuration, ping and Telnet to R2 from Sw1. If your configuration is correct, both tests should work.
