Cisco_单臂路由配置实验

Cisco 单臂路由配置实验拓扑：

交换机配置如下：

SW#vlan database

SW(vlan)#vlan 2

VLAN 2 added:

Name: VLAN0002

SW(vlan)#vlan 3

VLAN 3 added:

Name: VLAN0003

SW(vlan)#exit

SW(config)#int f0/2

SW(config-if)#switchport mode access

SW(config-if)#switchport access vlan 2

SW(config-if)#no shutdown

SW(config-if)#int f0/3

SW(config-if)#switchport mode access

SW(config-if)#switchport access vlan 3

SW(config-if)#no shutdown

SW(config-if)#int f0/1

SW(config-if)#switchport mode trunk

SW(config-if)#no shutdown

路由器配置如下：

R(config)#int f0/0

R(config-if)#no shutdown

R(config-if)#int f0/0.2

R(config-subif)#encapsulation dot1q 2

R(config-subif)#ip address 192.168.2.254 255.255.255.0

R(config-subif)#no shutdown

R(config-subif)#int f0/0.3

R(config-subif)#encapsulation dot1q 3

R(config-subif)#ip address 192.168.3.254 255.255.255.0

R(config-subif)#no shutdown

R(config-subif)#end

客户机配置如下：

HostA:

ip:192.168.2.1/24

ip default-gateway:192.168.2.254

HostB:

ip:192.168.3.1/24

ip default-gateway:192.168.3.254

测试连通性：

HostB#ping 192.168.2.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds: !!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 64/95/132 ms
