This support requirement applies to newer ASA devices. Support for IPsec Encryption with AES-GCM and IPsec Integrity with SHA-256, SHA-384, or SHA-512, requires ASA version 9.x. Support for DH Group and PFS Group beyond Group 5 requires ASA version 9.x. Support for IKEv2 requires ASA version 8.4 and later. * On some devices, IPsec Integrity must be a null value when the IPsec Encryption algorithm is AES-GCM. Consult your VPN device specifications to verify the algorithms that are supported for your VPN device models and firmware versions. The following table lists the IPsec/IKE algorithms and parameters that are used in the sample. This section lists the parameters for the sample. Virtual network and VPN gateway information You can optionally configure the BGP across the VPN tunnel.ДЇor step-by-step instructions to build the Azure configurations, see Single VPN tunnel setup. This configuration consists of a single S2S VPN tunnel between an Azure VPN gateway and an on-premises VPN device. If you specify an exact combination of algorithms and key strengths, be sure to use the corresponding specifications on your VPN devices.

You can optionally specify an exact combination of cryptographic algorithms and key strengths for a specific connection, as described in About cryptographic requirements. For the detailed IPsec/IKE protocol parameters and default cryptographic algorithms for Azure VPN gateways, see About VPN devices. VPN device requirementsДЄzure VPN gateways use the standard IPsec/IKE protocol suites to establish Site-to-Site (S2S) VPN tunnels. Consult your VPN device vendor specifications to verify that the IKEv2 policy is supported on your on-premises VPN devices. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. The connection uses a custom IPsec/IKE policy with the UsePolicyBasedTrafficSelectors option, as described in this article. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway. Azure VPN gateway type: Route-based VPN gateway.The example applies to Cisco ASA devices that are running IKEv2 without the Border Gateway Protocol (BGP). This article provides sample configurations for connecting Cisco Adaptive Security Appliance (ASA) devices to Azure VPN gateways. Sample configuration: Cisco ASA device (IKEv2/no BGP)
