思科模拟器配置-基本操作和vlan实训_思科模拟器配置vlan命令

根据下面的拓扑图进行配置，保证全网互通，VLAN间能互通

S1上配置VTY登录，限制3台主机，保存运行配置到启动配置文件。

S1(config)#line vty 0 2
S1(config-line)#exit
S1(config)#exit
S1#copy running-config startup-config 
Destination filename [startup-config]? 
Building configuration...
[OK]

S1使用本地数据库验证方式，添加用户a1:1234。配置特权加密口令为2345。

S1(config)#line vty 0 2
S1(config-line)#login local
S1(config-line)#exit
S1(config)#username a1 password 1234
S1(config)#enable password 2345

给各交换机配置VLAN，VLAN管理地址均为本网段最后一个地址。

S1:

S1(config)#vlan 50
S1(config-vlan)#vlan 60
S1(config-vlan)#exit
S1(config)#interface vlan 50
S1(config-if)#
%LINK-5-CHANGED: Interface Vlan50, changed state to up
S1(config-if)#ip address 172.0.50.254 255.255.255.0
S1(config-if)#exit
S1(config)#interface vlan 60
S1(config-if)#

S1上配单臂路由，S3上配三层交换路由。

配置各pc ip

S1：

S1(config)#interface fastEthernet 0/5
S1(config-if)#switchport mode access 
S1(config-if)#switchport access vlan 50
S1(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan50, changed state to up
S1(config-if)#exit
S1(config)#interface fastEthernet 0/6
S1(config-if)#switchport mode access 
S1(config-if)#switchport access vlan 60
S1(config-if)#

验证可用性：

S2：

S2(config)#vlan 10
S2(config-vlan)#vlan 20
S2(config-vlan)#exit
S2(config)#interface fastEthernet 0/1
S2(config-if)#switchport mode access 
S2(config-if)#switchport access vlan 10
S2(config-if)#exit
S2(config)#interface fastEthernet 0/6
S2(config-if)#switchport mode access 
S2(config-if)#switchport access vlan 20
S2(config-if)#exit

三层路由验证：

R0清除密码和所有配置，再配静态路由。

R0：

R0#erase startup-config
R0(config)#interface fastEthernet 0/1
R0(config-if)#no shutdown 
R0(config-if)#ip address 192.168.1.2 255.255.255.0
R0(config-if)#exit
R0(config)#interface fastEthernet 0/0
R0(config-if)#no shutdown 
R0(config-if)#ip address 192.168.0.1 255.255.255.0
R0(config-if)#exit
R0(config)#interface fastEthernet 1/0
R0(config-if)#no shutdown 
R0(config-if)#ip address 192.168.3.1 255.255.255.0
R0(config)#ip route 172.0.50.0 255.255.255.0 192.168.3.2
R0(config)#ip route 172.0.60.0 255.255.255.0 192.168.3.2

R1配置默认路由，保存配置文件，并复制到server0的TFTP服务器。

R1(config)#interface fastEthernet 0/1
R1(config-if)#no shutdown 
R1(config-if)#ip address 192.168.3.2 255.255.255.0
R1(config-if)#exit
R1(config)#
R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.3.1
