H3CNE小小综合实验
实验拓扑图
实验需求
- 按照图示配置IP地址
- 在SW1和SW2之间配置链路聚合增加链路带宽，提高可靠性
- PC5和PC6属于VLAN10， PC7和PC8属于VLAN20
- SW1和SW2属于二层交换机，SW3为三层交换机（VLAN100用于对接R4）,在交换机之间相连的链路
放行相关VLAN（不允许放行所有VLAN） - SW3作为DHCP服务器，配置两个地址池，分别为192.168.1.0/24网段和192.168.2.0/24网段网关分
别为192.168.1.254和192.168.2.254，dns统一为114.114.114.114；分别排除地址段192.168.1.1-
192.168.10和192.168.2.1-192.168.2.10 - 在R4上配置静态路由，使其有到达各个部门的路由，在SW3上配置默认路由，使其全网互通
- 在R4上配置Telnet服务使两个部门都能登录到R4
实现步骤
