This section describes sample configurations of an IPsec VPN on a Junos OS device using the following IKE authentication methods:

Configuring VPN on a Device Running Junos OS Overview

This section describes sample configurations of an IPsec VPN on a Junos OS device using the following IKE authentication methods:

Configuring an IPsec VPN with a Preshared Key for IKE Authentication
Configuring an IPsec VPN with an RSA Signature for IKE Authentication
Configuring an IPsec VPN with an ECDSA Signature for IKE Authentication

Figure 1 illustrates the VPN topology used in all the examples described in this section. Here, H0 and H1 are the host PCs, R0 and R2 are the two endpoints of the IPsec VPN tunnel, and R1 is a router to route traffic between the two different networks.

Note:

The router R1 can be a Linux-based router, a Juniper Networks device, or any other vendor router.

Figure 1: VPN Topology

Table 1 provides a complete list of the supported IKE protocols, tunnel modes, Phase 1 negotiation mode, authentication method or algorithm, encryption algorithm, DH groups supported for the IKE authentication and encryption (Phase1, IKE Proposal), and for IPsec authentication and encryption (Phase2, IPsec Proposal). The listed protocols, modes, and algorithms are supported and required for 22.2 R1 S1 Common Criteria.

Note:

The following sections provide sample configurations of IKEv1 IPsec VPN examples for selected algorithms. Authentication and encryption algorithms can be replaced in the configurations to accomplish the user’s desired configurations. Use set security ike gateway <gw-name> version v2-only command for IKEv2 IPsec VPN.

Configuring an IPsec VPN with a Preshared Key for IKE Authentication

In this section, you configure devices running Junos OS for IPsec VPN using a preshared key as the IKE authentication method. The algorithms used in IKE or IPsec authentication or encryption is shown in Table 2

Table 2: IKE or IPsec Authentication and Encryption
IKE Protocol	Tunnel Mode	Phase1 Negotiation Mode	Phase 1 Proposal (P1, IKE)
IKE Protocol	Tunnel Mode	Phase1 Negotiation Mode	Authentication Method	Authentication Algorithm	DH Group	Encryption Algorithm
IKEv1	Main	Route	pre-shared-keys	sha-256	group14	aes-256-cbc

IKE Protocol	Tunnel Mode	Phase1 Negotiation Mode	Phase 2 Proposal (P2, IPsec)
IKE Protocol	Tunnel Mode	Phase1 Negotiation Mode	Authentication Algorithm	DH Group (PFS)	Encryption Method	Encryption Algorithm
IKEv1	Main	Route	hmac-sha-256-128	group14	ESP	aes-256-cbc

Note:

A device running Junos OS uses certificate-based authentication or preshared keys for IPsec. TOE accepts ASCII preshared or bit-based keys up to 255 characters (and their binary equivalents) that contain uppercase and lowercase letters, numbers, and special characters such as !, @, #, $, %, ^, &, *, (, and ). The device accepts the preshared text keys and converts the text string into an authentication value as per RFC 2409 for IKEv1 or RFC 4306 for IKEv2, using the PRF that is configured as the hash algorithm for the IKE exchanges. The Junos OS does not impose minimum complexity requirements for preshared keys. Hence, users are advised to carefully choose long preshared keys of sufficient complexity.
