华为防火墙双机热备-主备旁挂组网

拓扑说明:FW1作为主墙、FW2作为备墙,进行双机热备,旁挂形式组网,PC访问路由器AR1的时候需要流量经过防火墙,并且在防火墙上做SNAT,PC地址对于路由器不可见。

结果:

访问的时候会话的状态
VGMP的状态
HRP状态

知识点:由于华为不能设置hrp track的优先级,当track接口down后,优先级会-2,然后会进行主备切换,当track接口为Eth-trunk接口的时候,可以设置Eth-trunk的成员的下限阈值来控制最小的端口活动数,如果不满足则down掉eth-trunk接口,如:least active-linknumber 2,就是当成员端口数量大于等于2的时候接口状态为UP,否者为DOWN。
