基于eNSP的多VLAN配置

实验名称
多VLAN配置
实验拓扑图如下

实验要求
1.全网可达;
2.使用DHCP获取IP地址;
实验思路
1.创建vlan域。
2.配置交换机的vlan。
3.配置路由器的vlan。
4.配置DHCP协议。
5.检查。
实验步骤
一
增添vlan域
S1
[S 3700 NO.1]vlan 2
[S 3700 NO.1-vlan2]quit
[S 3700 NO.1]vlan 3
[S 3700 NO.1-vlan3]quit

S2
[S 3700 NO.2]vlan 2
[S 3700 NO.2-vlan2]quit
[S 3700 NO.2]vlan 3
[S 3700 NO.2-vlan3]quit

S3
[S 3700 NO.3]vlan 2
[S 3700 NO.3-vlan2]quit
[S 3700 NO.3]vlan 3
[S 3700 NO.3-vlan3]quit

此时可以用【display vlan】命令来检查是否新增vlan域
如S1所示：

二
关联端口和vlan
S1
[S 3700 NO.1]int e0/0/2
[S 3700 NO.1-Ethernet0/0/2]port link-type access?
[S 3700 NO.1-Ethernet0/0/2]port default vlan 2
[S 3700 NO.1-Ethernet0/0/2]quit
[S 3700 NO.1]int e0/0/3
[S 3700 NO.1-Ethernet0/0/3]port link-type access?
[S 3700 NO.1-Ethernet0/0/3]port default ?vlan 3

S2
[S 3700 NO.2]int e0/0/3
[S 3700 NO.2-Ethernet0/0/3]port link-type access?
[S 3700 NO.2-Ethernet0/0/3]port default vlan 2
[S 3700 NO.2-Ethernet0/0/3]quit
[S 3700 NO.2]int e0/0/4
[S 3700 NO.2-Ethernet0/0/4]port link-type access?
[S 3700 NO.2-Ethernet0/0/4]port default ?vlan 3

S3
[S 3700 NO.3]int e0/0/2
[S 3700 NO.3-Ethernet0/0/2]port link-type access?
[S 3700 NO.3-Ethernet0/0/2]port default vlan 2
[S 3700 NO.3-Ethernet0/0/2]quit
[S 3700 NO.3]int e0/0/3
[S 3700 NO.3-Ethernet0/0/3]port link-type access?
[S 3700 NO.3-Ethernet0/0/3]port default ?vlan 3

此时可以用【display port vlan active】命令来检查是否关联
如S1所示

三
配置路由器
AR 1
[S 3700 NO.1]int e0/0/1
[S 3700 NO.1-Ethernet0/0/1]port link-type trunk
[S 3700 NO.1-Ethernet0/0/1]port trunk allow-pass vlan 2 3

AR2
[S 3700 NO.2]int e0/0/1
[S 3700 NO.2-Ethernet0/0/1]port link-type trunk
[S 3700 NO.2-Ethernet0/0/1]port trunk allow-pass vlan 2 3
[S 3700 NO.2-Ethernet0/0/1]quit
[S 3700 NO.2]int e0/0/2
[S 3700 NO.2-Ethernet0/0/2]port link-type trunk
[S 3700 NO.2-Ethernet0/0/2]port trunk allow-pass vlan 2 3

AR 3
[S 3700 NO.3]int e0/0/1
[S 3700 NO.3-Ethernet0/0/1]port link-type trunk
[S 3700 NO.3-Ethernet0/0/1]port trunk allow-pass vlan 2 3
四
配置路由器
AR1
增加单臂路由子接口
[AR 2220 NO.1]int g0/0/0.2
[AR 2220 NO.1-GigabitEthernet0/0/0.2]ip add 192.168.1.254 24
