    <Huawei>u t m
    [Huawei]sysname R1
    
    // 配置端口
    [R1]int g 0/0/0
    [R1-GigabitEthernet0/0/0]ip a 192.168.10.254 24
    [R1]int g 0/0/1
    [R1-GigabitEthernet0/0/1]ip a 192.168.20.254 24
    [R1]int g 0/0/2
    [R1-GigabitEthernet0/0/2]ip a 192.168.30.254 24
    
    // 配置静态路由
    [R1]ip route-static 192.168.40.0 24 192.168.30.253
    
    // 配置aaa认证
    [R1]aaa
    [R1-aaa]local-user admin password cipher 123456
    [R1-aaa]local-user admin service-type telnet
    [R1-aaa]local-user admin privilege level 15
    [R1]user-interface vty 0 4
    [R1-ui-vty0-4]authentication-mode aaa

  4. SW4设置

    // 基础配置
    <Huawei>u t m
    [Huawei]sysname SW4
    
    // VLAN及IP
    [SW4]int v 1
    [SW4-Vlanif1]ip a 192.168.40.2 24
    
    // 配置静态路由
    [SW4]ip route-static 192.168.10.0 24 192.168.40.254
    [SW4]ip route-static 192.168.20.0 24 192.168.40.254

  5. 测试

    在SW4中
    ping 192.168.10.1
    ping 192.168.20.1
    ping 192.168.40.1
    telnet 192.168.30.254	// 远程连接R1
    telnet 192.168.40.254	// 远程连接R2
