CLI举例：防火墙直路部署，上下行连接路由器的主备备份组网

2026年 3月 6日 中间件 SE_YT

介绍了业务接口工作在三层，上下行连接路由器的主备备份组网的CLI举例。

组网需求

如图1所示，两台FW的业务接口都工作在三层，上下行分别连接路由器。FW与上下行路由器之间运行OSPF协议。现在希望两台FW以主备备份方式工作。正常情况下，流量通过FW_A转发。当FW_A出现故障时，流量通过FW_B转发，保证业务不中断。

操作步骤

  1. 完成网络基本配置。 

    FW_A

    FW_B

    # 配置FW各接口的IP地址。

    		 
    <FW_A> system-view 
[FW_A] interface GigabitEthernet 1/0/1
[FW_A-GigabitEthernet1/0/1] ip address 10.2.0.1 24
[FW_A-GigabitEthernet1/0/1] quit 
[FW_A] interface GigabitEthernet 1/0/3
[FW_A-GigabitEthernet1/0/3] ip address 10.3.0.1 24
[FW_A-GigabitEthernet1/0/3] quit 
[FW_A] interface GigabitEthernet 1/0/7
[FW_A-GigabitEthernet1/0/7] ip address 10.10.0.1 24
[FW_A-GigabitEthernet1/0/7] quit
    		 
    <FW_B> system-view 
[FW_B] interface GigabitEthernet 1/0/1
[FW_B-GigabitEthernet1/0/1] ip address 10.2.1.1 24
[FW_B-GigabitEthernet1/0/1] quit 
[FW_B] interface GigabitEthernet 1/0/3
[FW_B-GigabitEthernet1/0/3] ip address 10.3.1.1 24
[FW_B-GigabitEthernet1/0/3] quit 
[FW_B] interface GigabitEthernet 1/0/7
[FW_B-GigabitEthernet1/0/7] ip address 10.10.0.2 24
[FW_B-GigabitEthernet1/0/7] quit

    # 将FW各接口加入相应的安全区域。

    		 
    [FW_A] firewall zone trust
[FW_A-zone-trust] add interface GigabitEthernet 1/0/3
[FW_A-zone-trust] quit 
[FW_A] firewall zone dmz
[FW_A-zone-dmz] add interface GigabitEthernet 1/0/7
[FW_A-zone-dmz] quit 
[FW_A] firewall zone untrust
[FW_A-zone-untrust] add interface GigabitEthernet 1/0/1
[FW_A-zone-untrust] quit
    		 
    [FW_B] firewall zone trust
[FW_B-zone-trust] add interface GigabitEthernet 1/0/3
[FW_B-zone-trust] quit 
[FW_B] firewall zone dmz
[FW_B-zone-dmz] add interface GigabitEthernet 1/0/7
[FW_B-zone-dmz] quit 
[FW_B] firewall zone untrust
[FW_B-zone-untrust] add interface GigabitEthernet 1/0/1
[FW_B-zone-untrust] quit

    # 在FW上配置OSPF，保证路由可达。

    		 
    [FW_A] ospf 10
[FW_A-ospf-10] area 0
[FW_A-ospf-10-area-0.0.0.0] network 10.2.0.0 0.0.0.255
[FW_A-ospf-10-area-0.0.0.0] network 10.3.0.0 0.0.0.255
[FW_A-ospf-10-area-0.0.0.0] quit
[FW_A-ospf-10] quit
    		 
    [FW_B] ospf 10
[FW_B-ospf-10] area 0
[FW_B-ospf-10-area-0.0.0.0] network 10.2.1.0 0.0.0.255
[FW_B-ospf-10-area-0.0.0.0] network 10.3.1.0 0.0.0.255
[FW_B-ospf-10-area-0.0.0.0] quit
[FW_B-ospf-10] quit

     

  2. 配置双机热备功能。 

    FW_A

    FW_B

    # 在FW上配置VGMP组监控上下行业务接口。

    		 
    [FW_A] hrp track interface GigabitEthernet 1/0/1
[FW_A] hrp track interface GigabitEthernet 1/0/3
    		 
    [FW_B] hrp track interface GigabitEthernet 1/0/1
[FW_B] hrp track interface GigabitEthernet 1/0/3

    # 在FW上配置根据VGMP状态调整OSPF Cost值功能。配置这个命令后，FW发布OSPF路由时，会判断自身是主用设备还是备用设备。如果是主用设备，FW会把学习到的路由直接发布出去；如果是备用设备，FW会增加Cost值后再将路由发布出去。这样上下行路由器在计算路由的时候，就能将下一跳指向主用设备，并把报文转发到主用设备上。

    		 
    [FW_A] hrp adjust ospf-cost enable
    		 
    [FW_B] hrp adjust ospf-cost enable

    # 在FW上指定心跳口并启用双机热备功能。

    		 
    [FW_A] hrp interface GigabitEthernet 1/0/7 remote 10.10.0.2
[FW_A] hrp enable
    		 
    [FW_B] hrp interface GigabitEthernet 1/0/7 remote 10.10.0.1
[FW_B] hrp standby-device
[FW_B] hrp enable

     

  3. 在FW_A上配置安全策略。双机热备状态成功建立后，FW_A的安全策略配置会自动备份到FW_B上。 

    # 配置安全策略，允许FW与上下行路由器交互OSPF报文。

    CLI举例：防火墙直路部署，上下行连接路由器的主备备份组网

    OSPF报文是否受安全策略控制决定于firewall packet-filter basic-protocol enable命令的配置。缺省情况下，firewall packet-filter basic-protocol enable处于开启状态，即OSPF报文受安全策略控制，需要在上下行业务接口所在安全区域与local区域之间配置安全策略，允许协议类型为OSPF的报文通过。本例以firewall packet-filter basic-protocol enable开启为例进行介绍。

    HRP_M[FW_A] security-policy
HRP_M[FW_A-policy-security] rule name policy_ospf_1 
HRP_M[FW_A-policy-security-rule-policy_ospf_1] source-zone local
HRP_M[FW_A-policy-security-rule-policy_ospf_1] destination-zone trust untrust
HRP_M[FW_A-policy-security-rule-policy_ospf_1] service ospf
HRP_M[FW_A-policy-security-rule-policy_ospf_1] action permit
HRP_M[FW_A-policy-security-rule-policy_ospf_1] quit
HRP_M[FW_A-policy-security] rule name policy_ospf_2 
HRP_M[FW_A-policy-security-rule-policy_ospf_2] source-zone trust untrust
HRP_M[FW_A-policy-security-rule-policy_ospf_2] destination-zone local
HRP_M[FW_A-policy-security-rule-policy_ospf_2] service ospf
HRP_M[FW_A-policy-security-rule-policy_ospf_2] action permit
HRP_M[FW_A-policy-security-rule-policy_ospf_2] quit

    # 配置安全策略，允许内网用户访问外网。

    HRP_M[FW_A-policy-security] rule name policy_sec 
HRP_M[FW_A-policy-security-rule-policy_sec] source-zone trust
HRP_M[FW_A-policy-security-rule-policy_sec] destination-zone untrust
HRP_M[FW_A-policy-security-rule-policy_sec] source-address 10.3.2.0 24
HRP_M[FW_A-policy-security-rule-policy_sec] source-address 10.3.3.0 24
HRP_M[FW_A-policy-security-rule-policy_sec] action permit

     

  4. 配置路由器。 

    分别在四台路由器上配置OSPF，发布相邻网段，具体配置命令请参考路由器的相关文档。

     

结果验证

在FW_A和FW_B上执行display hrp state verbose命令，检查当前VGMP组的状态，显示以下信息表示双机热备建立成功。
