Click the Add button to create a new IKE policy. A CCP default transform set is displayed. Click the Add button to create a new transform set.
b. Click the Add button to create a new IKE policy.
c. Set up the security policy as shown in the Add IKE Policy dialog box below. These settings are matched later on R3. When finished, click OK to add the policy. Then click Next. d. Click the Help button for assistance in answering the following questions. What is the function of the encryption algorithm in the IKE policy? The encryption algorithm encrypts and decrypts the payload of the control packets that pass over the secure IKE channel. CCNA Security All contents are Copyright © 1992 –2012 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 19 of 40 e. What is the purpose of the hash function? The hash validates that the entire control packet has not been tampered with during transit. The hash also authenticates the remote peer as the origin of the packet via a secret key. f. What function does the authentication method serve? Both endpoints verify that the IPsec traffic that they have received is sent by the remote IPsec peer. g. How is the Diffie-Hellman group in the IKE policy used? The Diffie-Hellman group is used by each of the endpoints to generate a shared secret key, which is never transmitted across the network. Each Diffie-Hellman group has an associated key length. h. What event happens at the end of the IK E policy’s lifetime? IKE renegotiates the IKE association. Step 6: Configure a transform set. The transform set is the IPsec policy used to encrypt, hash, and authenticate packets that pass through the tunnel. The transform set is the IKE Phase 2 policy.a. A CCP default transform set is displayed. Click the Add button to create a new transform set.
b. Set up the transform set as shown in the Transform Set dialog box below. These settings are matched later on R3. When finished, click OK to add the transform set. Then click Next. Step 7: Define interesting traffic. You must define interesting traffic to be protected through the VPN tunnel. Interesting traffic is defined through an access list applied to the router. By entering the source and destination subnets that you would like to protect through the VPN tunnel, CCP generates the appropriate simple access list for you. In the Traffic to protect window, enter the information as shown below. These are the opposite of the settings configured on R3 later in the lab. When finished, click Next. CCNA Security All contents are Copyright © 1992 –2012 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 20 of 40 Step 8: Review the summary configuration and deliver commands to the router. a. Review the Summary of the Configuration window. It should look similar to the one below. Do not select the checkbox for Test VPN connectivity after configuring. This is done after configuring R3. b. In the Deliver Configuration to router window, select Save running config to router ’s startup config and click the Deliver button. After the commands have been delivered, click OK. How many commands were delivered? 31 with CCP 2.5 CCNA Security All contents are Copyright © 1992 –2012 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 21 of 40 Task 3: Create a Mirror Configuration for R3 Step 1: Use CCP on R1 to generate a mirror configuration for R3. a. On R1, click the Configure button at the top of the CCP screen, and then choose Security VPN Site-to-Site VPN. Click the Edit Site to Site VPN tab. You should see the VPN configuration listed that you just created on R1. What is the description of the VPN? Tunnel to 10.2.2.1 b. What is the status of the VPN and why? Down. The IKE security association could not be established because the VPN peer R3 has not yet been configured. R3 must be configured with the appropriate VPN parameters, such as matching IKE proposals and IPsec policies and a mirrored access list, before the IKE and IPsec security associations will activate. c. Select the VPN policy you just configured on R1 and click the Generate Mirror button in the lower right of the window. The Generate Mirror window displays the commands necessary to configure R3 as a VPN peer. Scroll through the window to see all the commands generated. d. The text at the top of the window states that the configuration generated should only be used as a guide for setting up a site-to-site VPN. What commands are missing to allow this crypto policy to function on R3? The commands to apply the crypto map to the S001 interface. Hint: Look at the description entry following the crypto map SDM_CMAP_1 command. Step 2: Save the configuration commands for R3.a. Click the Save button to create a text file for use in the next task.
