H3C ER6300 + 两台 H3C S5120 组网举例
组网需求：
1、H3C ER6300 作出口路由、防火墙及Qos限速等功能（ER6300 配置LAN口 192.168.30.254默认网关）
2、H3C S5120 两台配置相同VLAN10 VLAN 20 VLAN 30并分配IP地址
VLAN 10 192.168.10.1/24 分配端口 Gi 1/0/1 - Gi 1/0/5
VLAN 20 192.168.20.1/24 分配端口 Gi 1/0/6 - Gi 1/0/10
VLAN 30 192.168.30.1/24 只在第一台交换机分配端口 Gi 1/0/30 用于与H3C ER6300 LAN口相连(第二台交换机不用分配端口)
3、H3C S5120 两台配置 Gi 1/0/47 - Gi 1/0/48端口为二层动态聚合接口1
4、H3C S5120两台配置静态默认路由指向H3C ER6300路由器默认网关 0.0.0.0 0.0.0.0 192.168.30.254
5、配置一台DHCP服务器192.168.20.20(windows server 2008 R2操作系统)连接到第一台H3C S5120交换机VLAN 20并配置DHCP中继代理
6、H3C ER6300路由器静态路由列表配置VLAN 10和VLAN 20回程路由
