Template applied to Service VPN 1, Source interface from VPN 0 (Internet Interface with public IP to reach external Firewall via Internet). These parameters are identical to the one that was received from ASA1. A vulnerability in the Internet Key Exchange Version 2 (IKEv2) implementation in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to prevent IKEv2 from establishing new security associations. We may get it in march release if everything will be on track. The problem is that a 'VPN Interface IPSEC' is not available: https://www.zscaler.com/resources/solution-briefs/partner-viptela-cisco-sd-wan-deployment.pdf. Responder sends the response for IKE_AUTH. You cannot configure IKEv2 through the user interface. In addition, this document provides information on how to translate certain debug lines in a configuration. The Responder tunnel usually comes up before the Initiator. Beginner. This section lists the configurations used in this document. This mode is more secure, and uses three . *Nov 11 19:30:34.835: IKEv2:KMI message 12 consumed. I have a working IPSEC project in GNS3 that uses csr1000 and 7200 routers, VTI interfaces, and IKEv1. IKEv2-ERROR:Address type 1622425149 not supported My assumption is that although the IPSEC is created on the service side, by sourcing the tunnel from the interface with a public IP address in VPN0, the cEdge would VRF jump to VPN0.

First pair of messages is the IKE_SA_INIT exchange. - edited if my config was wrong then tunnel shouldn't come up when Cisco ASA sending traffic. Components Used The information in this document is based on these software and hardware versions: Internet Key Exchange Version 2 (IKEv2) Cisco recommends that you have knowledge of the packet exchange for IKEv2. Source Interface in my setup is the WAN Interface connected to the Internet. E.g. If it guesses wrong, the CREATE_CHILD_SA exchange fails, and it will have to retry with a different KEi. tanyatamir53355. With IKEv1, you see a different behavior, because Child SA creation happens during Quick Mode, and the CREATE_CHILD_SA message has a provision to carry the Key Exchange payload that specifies the DH parameters to derive a new shared secret. IKEv2 allows the security association to remain unchanged despite changes in the underlying connection. 4 Sep 18 2018 17:40:58 750003 Local:80.x.y.z:500 Remote:51.a.b.c:500 Username:51.a.b.c IKEv2 Negotiation aborted due to ERROR: Detected unsupported . Let me ask you something - what format do you enter user/domain information in the client? The address range specifies that all traffic to and from that range are tunnelled. You can also check the output of theshow crypto sessioncommand on both routers; this output shows the tunnel session status as UP-ACTIVE. This is the CREATE_CHILD_SA response.
