摘要
双机热备是在网络出口处部署两台网关设备,以防一台设备出现故障而导致网络中断。使用华为路由器仿真模拟软件(eNSP)设计防火墙双机热备实验方案,分析了组管理协议(VGMP)和冗余备份协议(HRP),构建了以命令行方式配置防火墙双机热备的方案,并对实验结果进行了有效性验证。在具体的实验教学设计中,给出详细的配置方案设计,绘制了网络拓扑图,完成了防火墙的命令配置,最后进行了连通测试。
Dual-machine hot standby is to deploy two gateway devices at the network egress to prevent network interruption caused by the failure of one device.Using Huawei Router Simulation Software(eNSP)to design a firewall dual machine hot standby experimental scheme,analyze the Group Management Protocol(VGMP)and Redundant Backup Protocol(HRP),construct a solution for configuring firewall dual machine hot standby through command line mode,and validate the effectiveness of the experimental results.In the specific experimental teaching design,detailed configuration scheme design is provided,network topology diagram is drawn,firewall command configuration is completed,finally,connectivity testing is conducted.
