【实验步骤】
步骤1 配置三层交换机IP地址

Switch>en
Switch#conf t
Switch(config)#vlan 10
Switch(config-vlan)#ex

Switch(config)#vlan 50
Switch(config-vlan)#ex

Switch(config)#int f0/1
Switch(config-if)#switchport access vlan 10
Switch(config-if)#ex

Switch(config)#int f0/2
Switch(config-if)#switchport access vlan 50
Switch(config-if)#ex

Switch(config)#int f0/24
Switch(config-if)#switchport access vlan 10
Switch(config-if)#ex

Switch(config)#int vlan 10
Switch(config-if)#ip add 172.16.1.2 255.255.255.0
Switch(config-if)#no sh
Switch(config-if)#ex

Switch(config)#int vlan 50
Switch(config-if)#ip add 172.16.5.1 255.255.255.0
Switch(config-if)#no sh
Switch(config-if)#ex

Switch(config)#int f0/1
Switch(config-if)#sw
Switch(config-if)#switchport access vlan 10
Switch(config-if)#ex

Switch(config)#int f0/2
Switch(config-if)#switchport access vlan 50
Switch(config-if)#ex

Switch(config)#int f0/24
Switch(config-if)#switchport access vlan 10
Switch(config-if)#ex
Switch(config)#

步骤2 配置路由器IP地址

//路由器R-A:
Router>en
Router#conf t
Router(config)#hostname R-A
R-A (config)#int g0/0
R-A (config-if)#ip add 172.16.1.1 255.255.255.0
R-A (config-if)#no sh
R-A (config-if)#
R-A (config-if)#ex

R-A (config)#int g0/1
R-A (config-if)#ip add 172.16.2.1 255.255.255.0
R-A (config-if)#no sh
R-A (config-if)#ex

R-A (config)#int g0/2
R-A (config-if)#ip add 172.16.4.1 255.255.255.0
R-A (config-if)#no sh
R-A (config-if)#ex

//路由器R-B:
Router>en
Router#conf t
Router(config)#hostname R-B
R-B(config)#int g0/0
R-B(config-if)#ip add 172.16.2.2 255.255.255.0
R-B(config-if)#no sh
R-B(config-if)#
R-B(config-if)#ex

R-B(config)#int g0/1
R-B(config-if)#ip add 172.16.3.1 255.255.255.0
R-B(config-if)#no sh
R-B(config-if)#
R-B(config-if)#ex

R-B(config)#int g0/2
R-B(config-if)#ip add 172.16.6.1 255.255.255.0
R-B(config-if)#no sh
R-B(config-if)#
R-B(config-if)#ex
R-B(config)#

步骤3 配置OSPF路由协议

//三层交换机：
Switch>en
Switch#conf t
Switch(config)#ip routing //思科三层交换机需要加上此命令才能执行router ospf操作
Switch(config)#router ospf 1
Switch(config-router)#network 172.16.1.0 0.0.0.255 area 0
Switch(config-router)#network 172.16.5.0 0.0.0.255 area 0
Switch(config-router)#end

//路由器R-A
R-A>en
R-A#conf t
R-A(config)#router ospf 1
R-A(config-router)#network 172.16.1.0 0.0.0.255 area 0
R-A(config-router)#network 172.16.2.0 0.0.0.255 area 0
R-A(config-router)#network 172.16.4.0 0.0.0.255 area 0
R-A(config-router)#end

//路由器R-B
R-B>en
R-B#conf t
R-B(config)#router ospf 1
R-B(config-router)#network 172.16.2.0 0.0.0.255 area 0
R-B(config-router)#network 172.16.3.0 0.0.0.255 area 0
R-B(config-router)#network 172.16.6.0 0.0.0.255 area 0
R-B(config-router)#end

步骤4 配置电脑网关及IP地址

//PC0
网关：172.16.1.2
IP地址：172.16.1.3
子网掩码：255.255.255.0

//PC1
网关：172.16.5.1
IP地址：172.16.5.2
子网掩码：255.255.255.0

//PC2
网关：172.16.4.1
IP地址：172.16.4.2
子网掩码：255.255.255.0

//PC3
网关：172.16.3.1
IP地址：172.16.3.2
子网掩码：255.255.255.0

//PC4
网关：172.16.6.1
IP地址：172.16.6.2
子网掩码：255.255.255.0
