本实验要求：
通过在SW1来规划vlan 100，sw2上规划vlan200.因为vlan100和vlan200因为业务上的关系，需要两台pc之间相互通信，保证不同vlan之间可以互访。
实验过程：
第一步：配置sw1
sw1(config)# int f2/13
sw1(config-if)#no sw
//将2层变为3层
sw1(config-if)#ip add 12.0.0.1 255.255.255.0
sw1(config-if)#no sh
第二步：配置sw2
sw2(config)#int f2/13
sw2(config-if)#no sw
//将2层变为3层
sw2(config-if)#ip add 12.0.0.2 255.255.255.0
sw2(config-if)#no sh
第三步：在sw1上vlan配置
sw1#vlan da
sw1#vlan database
sw1(vlan)#vlan 100 name pc1-192
VLAN 100 added:
Name: pc1-192
sw1(vlan)#exi
APPLY completed.
Exiting....
sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#int f2/1
sw1(config-if)#sw mo acc
sw1(config-if)#sw acc vlan 100
sw1(config-if)#no sh
sw1(config-if)#spanning-tree portfast
sw1#sh vlan-s
VLAN Name Status Ports
1 default active Fa2/0, Fa2/2, Fa2/3, Fa2/4
Fa2/5, Fa2/6, Fa2/7, Fa2/8
Fa2/9, Fa2/10, Fa2/11, Fa2/12
Fa2/14, Fa2/15
100 pc1-192 active Fa2/1
1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active
VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2
1 enet 100001 1500 - - - - - 1002 1003
100 enet 100100 1500 - - - - - 0 0
1002 fddi 101002 1500 - - - - - 1 1003
1003 tr 101003 1500 1005 0 - - srb 1 1002
1004 fdnet 101004 1500 - - 1 ibm - 0 0
1005 trnet 101005 1500 - - 1 ibm - 0 0
第四步：在sw2上配置vlan
sw2#vlan da
sw2#vlan database
sw2(vlan)#vlan 200 name pc2-172
VLAN 200 added:
Name: pc2-172
sw2(vlan)#exi
APPLY completed.
Exiting....
sw2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw2(config)#int f2/2
sw2(config-if)#sw mo acc
sw2(config-if)#sw acc vlan 200
sw2(config-if)#spanning-tree portfast
第五步：在sw1 和sw2配置SVI（交换机虚拟接口）并给各自连接的pc配置相应的地址和网关（pc相关配置：略）
①SW1上的配置
sw1(config)#int vlan 100
sw1(config-if)#ip ad 172.16.0.1 255.255.255.0
sw1(config-if)#no sh
sw1#ping 192.168.0.200
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.200, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/20/56 ms
//在sw上ping pc
R1# ping 192.168.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/17/36 ms
//在pc1上ping网关
②SW上的配置
sw2(config)#int vlan 200
sw2(config-if)#ip add 1
sw2(config-if)#ip add 172.16.0.1 255.255.255.0
sw2(config-if)#no sh
sw2# ping 172.16.0.100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.0.100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/27/64 ms
//sw2上ping pc
R2#ping 172.16.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/22/48 ms
//从pc上ping sw2
第六步 ：在sw1和sw2上开启路由功能，这里我们运行动态路由协议，并查看路由协议
sw1(config)#router os
sw1(config)#router ospf 11
sw1(config-router)#net 12.0.0.1 0.0.0.255 a 0
sw1(config-router)#net 192.168.0.1 0.0.0.255 a 0
sw1(config-router)#end
sw2(config)#router ospf 11
sw2(config-router)#net 12.0.0.2 0.0.0.255 a 0
sw2(config-router)#net 172.16.0.1 0.0.0.255 a 0
sw1#sh ip rou
………………
172.16.0.0/24 is subnetted, 1 subnets
O 172.16.0.0 [110/2] via 12.0.0.2, 00:00:33, FastEthernet2/13
C 192.168.0.0/24 is directly connected, Vlan100
12.0.0.0/24 is subnetted, 1 subnets
C 12.0.0.0 is directly connected, FastEthernet2/13
sw2#sh ip rou
………………
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.0.0 is directly connected, Vlan200
O 192.168.0.0/24 [110/2] via 12.0.0.1, 00:00:58, FastEthernet2/13
12.0.0.0/24 is subnetted, 1 subnets
C 12.0.0.0 is directly connected, FastEthernet2/13
第七步：测试
R2#ping 192.168.0.200
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.200, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/77/108 ms
sw2# ping 172.16.0.100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.0.100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/18/52 ms
