    简介

    本文档介绍如何在两个Cisco路由器(Cisco IOS®或Cisco IOS® XE)之间配置基于策略的VPN over Internet Key Exchange(IKEv1)。

    先决条件

    要求

    本文档没有任何特定的要求。

    使用的组件

    本文档中的信息基于采用Cisco IOS®版本15.7的Cisco路由器。它允许用户通过IPsec VPN隧道跨站点访问资源。

    本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。

    规则

    有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

    配置

    本部分提供有关如何配置本文档所述功能的信息。

    网络图

    本文档使用以下网络设置：

    Network Diagram

    注意：此配置中使用的 IP 编址方案在 Internet 上不可合法路由。这些地址是在实验室环境中使用的 RFC 1918 地址。

    配置

    本文档使用以下配置：

    注意：Cisco建议应用到两台设备上的加密映射的ACL是彼此的镜像。

    Router A 
    !--- Create an ISAKMP policy for Phase 1 negotiations for the L2L tunnels.

crypto isakmp policy 10
encryption aes
hash sha256
authentication pre-share
group 14

!--- Specify the pre-shared key and the remote peer address 
    !--- to match for the L2L tunnel.

crypto isakmp key vpnuser address 10.0.0.2

!--- Create the Phase 2 policy for IPsec negotiation.

crypto ipsec transform-set myset esp-aes esp-sha256-hmac

!--- Create an ACL for the traffic to be encrypted.
!--- In this example, the traffic from 10.1.1.0/24 to 172.16.2.0/24
!--- is encrypted. The traffic which does not match the access list 
!--- is unencrypted for the Internet.

access-list 100 permit ip 10.1.1.0 0.0.0.255 172.16.2.0 0.0.0.255

!--- Create the actual crypto map. Specify an access control list (ACL),
    !--- which defines the proxy identities (local and remote host/networks).

 set peer 10.0.0.2
 set transform-set myset

!--- Apply the crypto map on the outside interface.
