%% 1. 外网连接 (R3模拟外网网关) InternetServer -- "8.8.8.0/24" --> R3 PC4 -- "172.16.1.0/24" --> R3

%% 2. ISP 到 出口 R3 -- "链路 A (203.0.113.0/30)" --> R1 R3 -- "链路 B (203.0.113.4/30)" --> R2

%% 3. 出口 到 防火墙 (Untrust 接口, ECMP) R1 -- "L3 链路 A (10.0.2.0/30)" --> FW1 R2 -- "L3 链路 B (10.0.3.0/30)" --> FW1

%% 4. 防火墙 到 核心 (Trust 接口) FW1 -- "L3 Eth-Trunk 2
(10.0.1.0/30)" --> CORE

%% 5. 防火墙 到 DMZ (DMZ 接口) - 关键变更点 FW1 -- "L2 链路 (VLAN 20)" --> S4

%% 6. 核心 到 接入 (Trust 接口) CORE -- "Trunk (VLAN 10)" --> S3 CORE -- "Trunk (VLAN 30)" --> S4

%% 7. 接入 到 终端 S3 -- "Access (VLAN 10)" --> PC1 S4 -- "Access (VLAN 30)" --> PC3 S4 -- "Access (VLAN 20)" --> Server
