The VPN tunnel between two devices fails with error "Unknown ikev2 peer," even if all the crypto profiles, pre-shared-keys and proxy IDs match. The client sends the initiator packet with the EAP payload. Since the EAP exchange is successful, the client sends the IKE_AUTH initiator packet with the AUTH payload. The documentation set for this product strives to use bias-free language. The client omits the AUTH payload from message 3 in order to indicate a desire to use extensible authentication. One of the peer is using IKEv1, and another peer is using IKEv2. View with Adobe Reader on a variety of devices, IKEv2 Packet Exchange and Protocol Level Debugging, RFC 3748, Extensible Authentication Protocol (EAP), RFC 5996, Internet Key Exchange Protocol Version 2 (IKEv2), Technical Support & Documentation - Cisco Systems. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Not exactly the question you had in mind? The information in this document is based on these software and hardware versions: The information in this document was created from the devices in a specific lab environment. It works with IPsec that is used to set up encrypted, authenticated communication tunnels between two IPsec peer devices. The client had requested that the user enter credentials. This payload is decrypted, and its contents are parsed as additional payloads. This could be verified through the packet captures asshown below. %ASA-5-752003: Tunnel Manager dispatching a KEY_ACQUIRE message to IKEv2. Learn more about how Cisco is using Inclusive Language.
