Cisco CCNA 之 Packet Tracer 练习题系列

项目5-1：配置VLAN间路由（三层交换）

拓扑：

项目说明：

假设核心交换机名称为：COM；分支交换机分别为：PAR1、PAR2、PAR3，分别通过Port 1的光线模块与核心交换机相连；并且假设VLAN名称分别为COUNTER、MARKET、MANAGING……

端口分配（交换机 PAR1、PAR2和 PAR3）

端口	分配	网络
Fa0/1-0/5	Native 99-NetworkMgmt	192.168.90.0 /24
Fa0/6-0/10	VLAN 10 �CCOUNTER	192.168.10.0 /24
Fa0/11 - 0/15	VLAN 20 - MARKET	192.168.20.0 /24
Fa0/16 - 0/24	VLAN 30 - MANAGING	192.168.30.0 /24

设备	Vlan	IP地址	子网掩码
COM	VLAN99	192.168.99.99	255.255.255.0
PAR1	VLAN99	192.168.99.1	255.255.255.0
PAR2	VLAN99	192.168.99.2	255.255.255.0
PAR3	VLAN99	192.168.99.3	255.255.255.0
PC0	网卡	192.168.10.2	255.255.255.0
PC1	网卡	192.168.20.2	255.255.255.0
PC2	网卡	192.168.30.2	255.255.255.0

项目目标

1、对交换机进行基本配置（密码为cisco）

2、设置VTP（核心、分支交换机上都设置 密码cisco 域名 czie）
3、配置中继（核心、分支交换机上都设置）
4、创建VLAN（在server上设置）
5、将交换机端口划入VLAN
6、配置三层交换使不同网段能相互ping通
