步骤五:配置对端网关设备

操作步骤

本示例对端网关以华为AR路由器为例。更多对端网关配置示例,请参见管理员指南

  1. 登录AR路由器配置界面。
  2. 进入系统视图。

    <AR651>system-view

  3. 配置公网接口的IP地址。本示例假设AR路由器GigabitEthernet 0/0/8为公网接口。

    [AR651]interface GigabitEthernet 0/0/8
    [AR651-GigabitEthernet0/0/8]ip address 22.xx.xx.22 255.255.255.0
    [AR651-GigabitEthernet0/0/8]quit

  4. 配置默认路由。

    [AR651]ip route-static 0.0.0.0 0.0.0.0 22.xx.xx.1

    其中,22.xx.xx.1为AR路由器公网IP的网关地址,请根据实际替换。

  5. 开启SHA-2算法兼容RFC标准算法功能。

    [AR651]IPsec authentication sha2 compatible enable

  6. 配置IPsec安全提议。

    [AR651]IPsec proposal hwproposal1
    [AR651-IPsec-proposal-hwproposal1]esp authentication-algorithm sha2-256
    [AR651-IPsec-proposal-hwproposal1]esp encryption-algorithm aes-128
    [AR651-IPsec-proposal-hwproposal1]quit

  7. 配置IKE安全提议。

    [AR651]ike proposal 2
    [AR651-ike-proposal-2]encryption-algorithm aes-128
    [AR651-ike-proposal-2]dh group14
    [AR651-ike-proposal-2]authentication-algorithm sha2-256
    [AR651-ike-proposal-2]authentication-method pre-share
    [AR651-ike-proposal-2]integrity-algorithm hmac-sha2-256
    [AR651-ike-proposal-2]prf hmac-sha2-256
    [AR651-ike-proposal-2]quit

  8. 配置IKE对等体。

    [AR651]ike peer hwpeer1
    [AR651-ike-peer-hwpeer1]undo version 1
    [AR651-ike-peer-hwpeer1]pre-shared-key cipher Test@123
    [AR651-ike-peer-hwpeer1]ike-proposal 2
    [AR651-ike-peer-hwpeer1]local-address 22.xx.xx.22
    [AR651-ike-peer-hwpeer1]remote-address 11.xx.xx.11
    [AR651-ike-peer-hwpeer1]rsa encryption-padding oaep
    [AR651-ike-peer-hwpeer1]rsa signature-padding pss
    [AR651-ike-peer-hwpeer1]ikev2 authentication sign-hash sha2-256
    [AR651-ike-peer-hwpeer1]quit
    [AR651]ike peer hwpeer2
    [AR651-ike-peer-hwpeer2]undo version 1
    [AR651-ike-peer-hwpeer2]pre-shared-key cipher Test@123
    [AR651-ike-peer-hwpeer2]ike-proposal 2
    [AR651-ike-peer-hwpeer2]local-address 22.xx.xx.22
    [AR651-ike-peer-hwpeer2]remote-address 11.xx.xx.12
    [AR651-ike-peer-hwpeer2]rsa encryption-padding oaep
    [AR651-ike-peer-hwpeer2]rsa signature-padding pss
    [AR651-ike-peer-hwpeer2]ikev2 authentication sign-hash sha2-256
    [AR651-ike-peer-hwpeer2]quit

    相关命令说明如下:

    • pre-shared-key cipher:预共享密钥,需要和VPN连接配置的预共享密钥保持一致。
    • local-address:AR路由器的公网地址。
    • remote-address:VPN网关的主EIP/主EIP2。

  9. 配置IPsec安全框架。

    [AR651]IPsec profile hwpro1
    [AR651-IPsec-profile-hwpro1]ike-peer hwpeer1
    [AR651-IPsec-profile-hwpro1]proposal hwproposal1
    [AR651-IPsec-profile-hwpro1]pfs dh-group14
    [AR651-IPsec-profile-hwpro1]quit
    [AR651]IPsec profile hwpro2
    [AR651-IPsec-profile-hwpro2]ike-peer hwpeer2
    [AR651-IPsec-profile-hwpro2]proposal hwproposal1
    [AR651-IPsec-profile-hwpro2]pfs dh-group14
    [AR651-IPsec-profile-hwpro2]quit

  10. 配置虚拟隧道接口。

    [AR651]interface Tunnel0/0/1
    [AR651-Tunnel0/0/1]mtu 1400
    [AR651-Tunnel0/0/1]ip address 169.254.70.1 255.255.255.252
    [AR651-Tunnel0/0/1]tunnel-protocol IPsec
    [AR651-Tunnel0/0/1]source 22.xx.xx.22
    [AR651-Tunnel0/0/1]destination 11.xx.xx.11
    [AR651-Tunnel0/0/1]IPsec profile hwpro1
    [AR651-Tunnel0/0/1]quit
    [AR651]interface Tunnel0/0/2
    [AR651-Tunnel0/0/2]mtu 1400
    [AR651-Tunnel0/0/2]ip address 169.254.71.1 255.255.255.252
    [AR651-Tunnel0/0/2]tunnel-protocol IPsec

    [AR651-Tunnel0/0/2]destination 11.xx.xx.12
    [AR651-Tunnel0/0/2]IPsec profile hwpro2
    [AR651-Tunnel0/0/2]quit

    相关命令说明如下:

    • interface Tunnel0/0/1、interface Tunnel0/0/2:两条VPN连接对应的Tunnel隧道。

      本示例中,Tunnel0/0/1对应VPN网关主EIP所在的VPN连接;Tunnel0/0/2对应VPN网关主EIP2所在的VPN连接。

    • ip address:AR路由器的Tunnel接口地址。
    • source:AR路由器的公网地址。
    • destination:VPN网关的主EIP/主EIP2。

  11. 配置NQA。

    [AR651]nqa test-instance IPsec_nqa1 IPsec_nqa1
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]test-type icmp
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]destination-address ipv4 169.254.70.2
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]source-address ipv4 169.254.70.1
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]frequency 15
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]ttl 255
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]start now
    [AR651-nqa-IPsec_nqa1-IPsec_nqa1]quit
    [AR651]nqa test-instance IPsec_nqa2 IPsec_nqa2
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]test-type icmp
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]destination-address ipv4 169.254.71.2
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]source-address ipv4 169.254.71.1
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]frequency 15
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]ttl 255
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]start now
    [AR651-nqa-IPsec_nqa2-IPsec_nqa2]quit

    相关命令说明如下:

    • nqa test-instance IPsec_nqa1 IPsec_nqa1、nqa test-instance IPsec_nqa2 IPsec_nqa2:NQA名称。

      本示例中,IPsec_nqa1对应VPN网关主EIP所在的VPN连接;IPsec_nqa2对应VPN网关主EIP2所在的VPN连接。

    • destination-address:VPN网关的Tunnel接口地址。
    • source-address:AR路由器的Tunnel接口地址。

  12. 配置静态路由联动NQA功能。

    [AR651]ip route-static 192.168.0.0 255.255.255.0 Tunnel0/0/1 track nqa IPsec_nqa1 IPsec_nqa1
    [AR651]ip route-static 192.168.0.0 255.255.255.0 Tunnel0/0/2 track nqa IPsec_nqa2 IPsec_nqa2

    相关参数说明如下:

    • 192.168.0.0:VPC的本端子网。
    • 同一条命令中,Tunnelx和IPsec_nqax需要同属于一条VPN连接。

结果验证

  1. 登录管理控制台。
  2. 在页面左上角单击图标,选择区域,选择网络 > 虚拟专用网络VPN
  3. 在左侧导航栏,单击虚拟专用网络 > 企业版-VPN连接

    此时可以看到两条VPN连接状态均变为“正常”
