ASA1(config-if)# no shutdown, Interface IP-Address OK? Is there any impact of enabling IKEv2 to existing IPSec tunnels configured with IKEv1. The Cisco ASA is often used as VPN terminator, supporting a variety of VPN types and protocols. Router(config-ikev2-profile)#authentication remote pre-share . Now we have a CA operating, we need to generate a certificate for our router to identify itself to clients. You can check that the certificate is installed with: Below I have allowed for users VPNing in to get an IP address from 192.168.255.1 to 192.168.255.254. A connection must exist between the Cisco CG-OS router and the head-end router before you can configure a virtual tunnel interface between the two systems. Following are the phase 1 and phase 2 requirements. authentication pre-share Keyring: configure the key will be exchanged to establish phase1 and the type which is in our example (pre-shared) Example: #crypto ikev2 keyring cisco. #peer R3. DETAILED STEPS EXAMPLE Example 1: RSA Authentication This example shows how to enable IKEv2 and then create a virtual IPSec tunnel when employing RSA authentication for both the Cisco CG-OS router and the head-end router. Take a break, you have now completed the main config on the router, and its time to move onto just want to keep your Cisco technology current. Contact the system administrator to confirm the authentication method (PSK or RSA) to configure on the Cisco CG-OS router. As opposed to IKEv1, where we configured a transform set that combines the encryption and authentication method, with IKEv2 we can configure multiple encryption and authentication types, and multiple integrity algorithms for a single policy. Its pretty critical that your router has at least the right date. 2) Click the Add button to create a new profile. This section needs to be repeated for each user you want to be able to VPN in. to your router. Once your request has been generated, save it to your computer and send it off to your CA (Certificate Authority) for signing.Once youve received your signed certificate back from your CA, head back over to the Crypto Maps page in the Cisco ASR 1000 web interface and click on your map entry again. Finally, we will create a crypto map linking the access list, the peer and the IKEv2 proposal. IFM supplies network engineering services for $NZ180+GST per hour. or later.
