引言

传统VRRP方式无法实现主、备用防火墙状态信息和多组VRRP状态的一致性，所以可能会导致流量的回包不从首包通过的防火墙回包，防火墙会因为状态检测机制丢弃此报文，所以防火墙使用VGMP统一管理VRRP的状态。

双机热备的部署模式有三种，主备备份、负载分担、镜像模式。其中主备分担和镜像模式的VGMP的状态，主是active，备是standby；而负载分担模式中，两个防火墙的状态都是load-balance。

主备备份实验

1、基本配置

FW1：（配置地址、VRRP、接口加入安全区域）

[FW1]interface GigabitEthernet1/0/0
[FW1-GigabitEthernet1/0/0] ip address 192.168.10.2 24
[FW1-GigabitEthernet1/0/0] vrrp vrid 1 virtual-ip 192.168.10.1 active

[FW1]interface GigabitEthernet1/0/1
[FW1-GigabitEthernet1/0/1] ip address 1.1.1.2 29
[FW1-GigabitEthernet1/0/1] vrrp vrid 2 virtual-ip 1.1.1.1 active

[FW1]interface GigabitEthernet1/0/2
[FW1-GigabitEthernet1/0/2] ip address 10.1.1.1 30[FW1]firewall zone trust
[FW1-zone-trust] add interface GigabitEthernet1/0/0

[FW1]firewall zone untrust                     
[FW1-zone-untrust] add interface GigabitEthernet1/0/1

[FW1]firewall zone name hrp
[FW1-zone-hrp] set priority 51
[FW1-zone-hrp] add interface GigabitEthernet1/0/2

FW2：（配置地址、VRRP、接口加入安全区域）

[FW2]interface GigabitEthernet1/0/0
[FW2-GigabitEthernet1/0/0] ip address 192.168.10.3 24
[FW2-GigabitEthernet1/0/0] vrrp vrid 1 virtual-ip 192.168.10.1 standby

[FW2]interface GigabitEthernet1/0/1
[FW2-GigabitEthernet1/0/1] ip address 1.1.1.3 29
[FW2-GigabitEthernet1/0/1] vrrp vrid 2 virtual-ip 1.1.1.1 standby

[FW2]interface GigabitEthernet1/0/2
[FW2-GigabitEthernet1/0/2] ip address 10.1.1.2 30

[FW2]firewall zone trust
[FW2-zone-trust] add interface GigabitEthernet1/0/0

[FW2]firewall zone untrust                     
[FW2-zone-untrust] add interface GigabitEthernet1/0/1

[FW2]firewall zone name hrp
[FW2-zone-hrp] set priority 51
[FW2-zone-hrp] add interface GigabitEthernet1/0/2

2、双机热备配置

FW1：（配置心跳接口、开启HRP）

[FW1]hrp interface G1/0/2 remote 10.1.1.2
[FW1]hrp enable

FW2：（配置心跳接口、开启HRP）

[FW2]hrp interface g1/0/2 remote 10.1.1.1
[FW2]hrp enable

查看双机热备状态

FW1：（作为主设备，Role 为Active）

验证备机无法配置安全策略、NAT策略等等，比如进入NAT策略的视图都会报错。

HRP_S[FW2]nat-policy Error: The device is in HRP standby state, so this command can not be executed.

主备切换

FW1：关闭主防火墙的一个配置了VRRP的接口

HRP_M[FW1]interface g1/0/1 (+B)
HRP_M[FW1-GigabitEthernet1/0/1]shutdown

FW1：主防火墙的角色会立马发生转变，变成Role 是 Standby

HRP_S[FW1]display hrp state  
2025-03-16 03:14:00.580 Role: standby, peer: active (should be "active-standby")Running priority: 44998, peer: 45000Backup channel usage: 0.00%Stable time: 0 days, 0 hours, 0 minutesLast state change information: 2025-03-16 3:13:45 HRP core state changed, old_state = normal, new_state = abnormal(standby), local_priority = 44998, peer_priority = 45000.

FW2：备防火墙的角色会立马发生转变，变成Role 是 Active


HRP_M[FW2]display hrp state
2025-03-16 03:14:12.050 Role: active, peer: standby (should be "standby-active")Running priority: 45000, peer: 44998Backup channel usage: 0.00%Stable time: 0 days, 0 hours, 0 minutesLast state change information: 2025-03-16 3:13:44 HRP core state changed, old_state = normal, new_state = abnormal(active), local_priority = 45000, peer_priority = 44998.

FW1：恢复主防火墙的接口，查看切换状态

HRP_S[FW1]interface g1/0/1 (+B)
HRP_S[FW1-GigabitEthernet1/0/1]undo shutdown

（主防火墙一分钟之后会抢占回来，因为默认的抢占就是60S）

路由影响

双机热备除了主墙响应VRRP的地址以外，对于网络中路由的宣告也有影响。

备墙会增加OSPF、ISIS、BGP的cost值，从而影响网络的流量，走到主墙上。（在最后几行）

HRP_S[FW2]display hrp state verbose

查看会话表

FW1：

FW2：（因为是备墙，所以会同步主墙的会话表，所以带有remote字样）

HRP_S[FW2]display firewall session table
