IKEv2 IPsec Site-to-Site VPNs

IKEv2 has streamlined the original IKEv1 packet exchanges during Phase 1 and Phase 2 operation (Main mode, Aggressive mode, and Quick mode) used to create IKE and IPsec SAs for a secure communications tunnel. Unlike IKEv1, which uses either nine messages (Main mode = 6 + Quick mode = 3 or 6 messages (Aggressive mode = 3 + Quick mode = 3) for successful operation.

IKEv2 introduces a new packet-exchange process using only four messages (Note that additional child SAs require further packet exchanges, so this number may increase).

A successful IKEv2 message exchange involves a pair of messages for each of the phases listed here, which have been created to replace the older IKEv1 Phase 1 and Phase 2 negotiations. The corresponding IKEv1 "phases" are shown next to the relevant IKEv2 phase for your reference:

* IKE_SA_INIT (Phase 1)

* IKE_AUTH (Phase 1 and 2)


Phase 1

The first exchange, IKE_SA_INIT, is used to negotiate the security parameters by sending IKEv2 proposals, including the configured encryption and integrity protocols, Diffie-Hellman values, and nonces (random) numbers. At this point, the two peers generate SKEYSEED (a seed security key value), from which all future IKE keys are generated. The messages that follow in later exchanges are encrypted and authenticated using keys generated from the SKEYSEED value.


Phase 2

The second exchange, IKE_AUTH, operates over the IKE_SA created by the IKE_SA_INIT exchanges and is used to validate the identity of the peers and negotiate the various encryption, authentication, and integrity protocols to establish the first CHILD_SA for use by ESP or AH in which IPsec communication occurs. Peers are validated using PSKs, certificates, or Extensible Authentication Protocol (EAP) (allowing for legacy authentication methods between peers).

The first CHILD_SA created in the second exchange (Phase 2) is commonly the only SA created for IPsec communication. However, if an application or peer requires the use of additional SAs to secure traffic through an encrypted tunnel, IKEv2 uses the CREATE_CHILD_SA exchange. During the CREATE_CHILD_SA exchange, new Diffie-Hellman values may be generated and cryptographic protocols used (That is, there is no requirement for later SAs to use the same key material created during the initial IKE_SA_INIT exchange). This behavior is similar in function to the use of PFS, whereby during an IKEv1 Quick mode exchange, new Diffie-Hellman values may be used to prevent the reuse of key material created in the previous Phase 1 exchanges. If you do not want to multiplex multiple source/destination traffic pairs over the same SA, you'll usually have multiple CREATE_CHILD_SA exchanges to create multiple SAs for securing data traffic.

IKEv1 IPsec Site-to-Site VPN

IKEv1 provides a framework for the parameter negotiation and key exchange between VPN peers for the correct establishment of a (Security Association) SA.

However, the actual processes of key exchange and parameter negotiation are carried out by two protocols used by IKEv1:

* Internet Security Association and Key Management Protocol (ISAKMP)

* Oakley

ISAKMP takes care of parameter negotiation between peers (for example, DH groups, lifetimes, encryption and authentication). The process of negotiating these parameters between peers is required for the successful establishment of SAs. After an SA has been established, ISAKMP defines the procedures followed for correct maintenance and removal of the SA during connection termination.

Note: You will often find the terms ISAKMP and IKE used interchangeably in earlier versions of ASA (pre 8.4) and IOS reference IKEv1 functions and parameters.

Two mandatory IKEv1 phases (aptly named IKEv1 Phase 1 and IKEv1 Phase 2) must be followed by each peer before a communications tunnel can be established between them and they are ready for successful data transmision:

* IKEv1 Phase 1: During this phase, both peers negotiate parameters (integrity and encryption algorithms, authentication methods) to set up a secure and authenticated tunnel. This is also called a management channel because no user data is flowing through it (and it is actually a bidirectional IKE SA). Its sole scope is to handle secure Phase 2 negotiations. It is called bidirectional because both peers use only one session key to secure both incoming and outgoing traffic. Peer authentication can be carried out by one of the following methods:

    - Pre-shared keys

    - Digital certificates

* IKEv1 Phase 2: This second mandatory phase uses the negotiated parameters in Phase 1 for secure IPsec SA creation. However, unlike the single bidirectional SA created within Phase 1, the IPsec SA are unidirectional, meaning a different session key is used for each direction (one for inbound, or decrypted, traffic, and one for outbound, or encrypted, traffic). This is applicable for any administrator-configured source-destination network pair. Therefore, you might end up with four unidirectional IPsec SAs if you have two source-destination network pairs defined in a VPN policy.

I used my 871w IOS router and ASA 5505 firewall to establish an IKEv1 IPsec site-to-site VPN tunnel. This will help demonstrate the similarities and differences in configuring and troubleshooting for IKE Phase 1 and IKE Phase 2 VPN policies.
