How do I enable IKEv2 on my Cisco router?

What’s the difference between IKEv1 and IKEv2?

IKEv2 uses four messages; IKEv1 uses either six messages (in the main mode) or three messages (in aggressive mode). IKEv2 has Built-in NAT-T functionality which improves compatibility between vendors. IKEv2 supports EAP authentication. IKEv2 has the Keep Alive option enabled as default.

How do I troubleshoot IPSec tunnel?

If tunnels are up but traffic is not passing through the tunnel:

  1. Check security policy and routing.
  2. Check for any devices upstream that perform port-and-address-translations.
  3. Apply debug packet filters, captures or logs, if necessary, to isolate the issue where the traffic is getting dropped.

How do I verify VPN tunnel?

To verify that your VPN tunnel is working properly, it is necessary to ping the IP address of a computer on the remote network. By pinging the remote network, you send data packets to the remote network and the remote network replies that it has received the data packets.

Why are there only two packets in Ike_SA_init?

The exchanges contain only two packets because it combines all the information usually exchanged in MM1-4 in IKEv1. As a result, the responder is computationally expensive to process the IKE_SA_INIT packet and can leave to process the first packet; it leaves the protocol open to a DOS attack from spoofed addresses.

What happens after the Ike_SA_init exchange is complete?

After the IKE_SA_INIT exchange is complete, the IKEv2 SA is encrypted; however, the remote peer has not been authenticated. The IKE_AUTH exchange is used to authenticate the remote peer and create the first IPsec SA.
