In the IKEv1 Phase 1 settings, you can select one of these modes: Main Mode. This exchange consists of a single request/response pair and was referred to as a phase 2 exchange in IKEv1. 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. Thanks again for this article. If the SA offers include different DH groups, KEi must be an element of the group the initiator expects the responder to accept.

Hi, made some more tests and my problem is the following, IPSec tunnel can be established if remote end is configured without any specific encryption domains for the communication and with a transport network within the tunnel (for routing purpose - like in GRE Tunnel). If the proposal is acceptable to the responder, it sends identical TS payloads back. The IKE_AUTH packet contains: ISAKMP Header(SPI/ version/flags), IDi(initiator's identity), AUTH payload, SAi2(initiates the SA-similar to the phase 2 transform set exchange in IKEv1), and TSi and TSr (Initiator and Responder Traffic selectors): They contain the source and destination address of the initiator and responder respectively for forwarding/receiving encrypted traffic. Responder verifies and processes the IKE_INIT message: (1) Chooses crypto suite from those offered by the initiator, (2) computes its own DH secret key, and (3) it computes a skeyid value, from which all keys can be derived for this IKE_SA.

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.
