.
实验过程：
第一步：配置sw1
sw1 (config)#ip routing
sw1(config)#int f2/1
sw1(config-if)#sw mo acc
sw1(config-if)#sw acc vlan 100
sw1(config-if)#int f2/2
sw1(config-if)#sw mo acc
sw1(config-if)#sw acc vlan 200
sw1(config)#int vlan 100
sw1(config-if)#ip add 192.168.1.1 255.255.255.0
sw1(config-if)#no sh
sw1(config-if)#int vlan 200
sw1(config-if)#ip add 172.16.1.1 255.255.255.0
sw1(config-if)#no sh
第二步：在R1和R2上进行配置，它们模拟pc
R1(config)#no ip routing
R1(config)#int e0/1
R1(config-if)#ip add 192.168.1.2 255.255.255.0
R1(config-if)#no sh
R1(config)#ip default-gateway 192.168.1.1
R2(config)#no ip routing
R2(config)#ip default-gateway 172.16.1.1
R2(config)#int e0/1
R2(config-if)#ip add 172.16.1.2 255.255.255.0
R2(config-if)#no sh
第三步：测试
R1#ping 172.16.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/71/104 ms
R1#
R2#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/65/84 ms
R2#
