三层交换机配置综合实验

实验拓扑

第一步，配置VTP域，创建VLAN
3550：
3550#vlan database
3550(vlan)#vtp server
3550(vlan)#vtp domain sy
3550(vlan)#vtp password cisco
3550(vlan)#vlan 2
3550(vlan)#vtp 3
3550(vlan)#vtp pruning
3550(vlan)#exit

SW1:
SW1#vlan database
SW1(vlan)#vtp client
SW1(vlan)#vtp domain sy
SW1(vlan)#vtp password cisco
SW1(vlan)#exit

 

第二步，设置中继
3550：
3550（config）#int f0/0
3550(config-if)#switchport trunk encapsulation dot1q
3550(config-if)#switchport mode trunk
3550(config-if)#end
3550#show vtp status
VTP Version                 :2
Confiugration Revision          :2
Maximum VLANs supported locally :256
Number of existing VLANs       :7
VTP Operating Mode            :Server
VTP Domain Name              :sy
VTP Pruning Mode               :Enabled
VTP V2 Mode                   :Disabled
VTP Traps Generation              :Disabled

 

SW1:
SW1(config)#int f0/15
SW1(config-if)#switchport trunk encapsulation dot1q
SW1(config-if)#switchport mode trunk
SW1(config-if)#end
SW1#show vtp status
VTP Version                   :2
Configuration Revision            :2
Maximum VLANs supported locally:256
Number of existing vlans          :7
VTP Operating Mode              :Client
VTP Domain Name                :sy
VTP Pruning Mode                 :Enabled
VTP V2 Mode                      :Disabled
VTP Traps Generation                :Disabled

第三步，端口加入VLAN
SW1：
SW1#conf t
SW1(config)#int f0/1
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 2
SW1(config-if)#exit

SW1(config)#int f0/2
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 3
SW1(config-if)#end

 

第四步，配置三层交换，实现VLAN之间互通
3550
3550#conf t
3550(config)#ip routing
3550(config)#int vlan 2
3550(config-if)#ip address 192.168.2.1 255.255.255.0
3550(config-if)#no shutdown
3550(config-if)#exit
3550(config)#int vlan 3
3550(config-if)#ip address 192.168.3.1 255.255.255.0
3550(config-if)#no shutdown
3550(config-if)#exit

 

第五步，客户机验证
PC1#ping 192.168.3.3
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to 192.168.3.3,timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 216/284/336 ms
PC2#ping 192.168.2.2
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to 192.168.2.2,timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 144/211/276 ms

 

第六步，在三层交换机上启用路由功能
3550
3550（config）#int f0/1
3550(config-if)#no switchport
3550(config-if)# ip address 172.16.1.1 255.255.255.0
3550(config-if)#no shutdown
3550(config-if)#exit
3550(config)#int f0/2
3550(config-if)#no switchport
3550(config-if)# ip address 172.16.2.1 255.255.255.0
3550(config-if)#no shutdown
3550(config-if)#exit

 

第七步，配置两台路由器，并启用HSRP
R1：
R1（config）#
R1（config）#int f0/0
R1（config-if）#no ip address
R1(config-if)# ip address 172.16.1.2 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#speed 100
R1(config-if)#duplex full
R1(config-if)#exit
R1(config)#int f1/0
R1(config-if)# ip address 10.0.0.254 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#speed 100
R1(config-if)#duplex full
R1(config-if)#standby 1 ip 10.0.0.252
R1(config-if)#standby 1 priority 200
R1(config-if)#standby 1 preempt
R1(config-if)#standby 1 track f0/0 10
R1(config-if)#end
R1#show standby brief
             P indicates configured to preempt.
              /
Interface grp prio p state active     standby      virtual ip
Fa1/0   1 200 p active local    10.00.253     10.0.0.252

R2:
R2#conf t
R2(config)#int f0/0
R2(config-if)# ip address 172.16.2.2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#speed 100
R2(config-if)#duplex full
R2(config-if)#exit
R2(config)#int f1/0
R2(config-if)# ip address 10.0.0.253 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#speed 100
R2(config-if)#duplex full
R2(config-if)#standby 1 ip 10.0.0.252
R2(config-if)#end

第八步，配置动态路由协议
3550：
3550（config）#router ospf 1
3550（config-router）#network 192.168.2.0.0.0.0.255.area 0
3550（config-router）#network 192.168.3.0.0.0.0.255.area 0
3550（config-router）#network 172.16.1.0.0.0.0.255.area 0
3550（config-router）#network 172.16.2.0.0.0.0.255.area 0
3550（config-router）#end

R1:
R1（config）#router ospf 2
R1（config-router）#network 172.16.1.0.0.0.0.255.area 0
R1（config-router）#network 10.0.0.0.0.0.0.255.area 0
R1（config-router）#end

R2:
R2（config）#router ospf 3
R2（config-router）#network 172.16.2.0.0.0.0.255.area 0
R2（config-router）#network 10.0.0.0.0.0.0.255.area 0
R2（config-router）#end
R2#show ip route Gateway of last resort is not set
   172.16.0.0/24 is subnetted,2 subnets
O     172.16.1.0[110/2] via 172.16.2.1,00:03:39,FastEthernet0/0
             [110/2] via 10.0.0.254,00:03:39,FastEthernet0/0
C     172.16.2.0 is directly connected,FastEthernet0/0
     10.0.0.0/24 is subnetted,1 subnets
C          10.0.0.0 is directly connected,FastEthernet1/0
O      192.168.2.0/24 [110/2] via 172.16.2.1,00:03:39, FastEthernet0/0
O      192.168.3.0/24 [110/2] via 172.16.2.1,00:03:39, FastEthernet0/0

第九步，客户机验证
PC3#ping 192.168.2.2
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to 192.168.2.2,timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 288/337/432 ms
PC3#ping 192.168.3.3
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to 192.168.3.3,timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 240/300/336 ms
PC1#ping 192.168.3.3
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to 192.168.3.3,timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 192/231/288 ms
以上就是三层交换机配置综合实验。希望对大家有所帮助。
