一、实验拓扑 

二、实验要求

内网IP地址172.16.0.0/16合理分配
SW1/2之间互为备份
VRBP/STP/LANTRUNK均使用
所有PC通过DHCP获取ip地址
 

三、实验步骤

 首先思考进行IP地址的规划

配置eht-trunk

[sw1]interface  Eth-Trunk 0
[sw1-Eth-Trunk0]q
[sw1-GigabitEthernet0/0/1]int g0/0/2
[sw1-GigabitEthernet0/0/2]eth-trunk 

[wa2]interface Eth-Trunk 0
[wa2-Eth-Trunk0]  
[wa2-GigabitEthernet0/0/1]eth-trunk 0
[wa2-GigabitEthernet0/0/2]eth-trunk 0

查询 eht-trunk

 创建VLAN
[sw1]vlan 2
[sw1-vlan2]
[sw2]vlan 2
[sw2-vlan2]
[sw3]vlan 2
[sw3-vlan2]
[sw4]vlan 2
[sw4-vlan2]

划分VLAN

[sw3-Ethernet0/0/4]port link-type access 

[sw3-Ethernet0/0/4]port default vlan 2

[sw4-Ethernet0/0/4]port link-type access 
[sw4-Ethernet0/0/4]port default vlan 2

 配置trunk

[sw1]port-group group-member Eth-Trunk 0 Ethernet0/0/1 to Ethernet 0/0/2

[sw1-port-group]port link-type trunk     
[sw1-port-group]port trunk allow-pass vlan 2

[wa2]port-group group-member Eth-Trunk 0 Ethernet0/0/1 to Ethernet 0/0/2 

[wa2-port-group]port link-type trunk 

[wa2-port-group]port trunk allow-pass vlan 2

[sw4]port-group group-member Ethernet0/0/1 to Ethernet 0/0/2
[sw4-port-group]port link-type trunk 
[sw4-port-group]port trunk allow-pass  vlan 2

[sw3]port-group group-member Ethernet0/0/1 to Ethernet 0/0/2
[sw3-port-group]port link-type trunk 
[sw3-port-group]port trunk allow-pass  vlan 2

 查询配置是否成功

 

 调整生成树 

分组

[sw1]stp enable 
[sw1]stp region-configuration 
[sw1-mst-region]region-name a
[sw1-mst-region]instance 1 vlan 1  
[sw1-mst-region]instance 2 vlan 2
[sw1-mst-region]active region-configuration

 其他交换机配置一样

做备份

[sw1]stp instance 2 root secondary 

[sw1]stp instance 1 root primary

[wa2]stp instance 2 root primary

[wa2]stp instance 1 root secondary

 查询（仅展示部分）

调整用户接口类型

[sw3]port-group group-member Ethernet  0/0/3 to Ethernet 0/0/4

[sw3-port-group]stp edged-port enable

交换机4配置同理

配置SVI 

[sw1]interface vlan 1
[sw1-Vlanif1]ip address 172.16.1.1 25

[sw1]int vlan 2   
[sw1-Vlanif2]ip address 172.16.1.129 25

[wa2]int vlan 1
[wa2-Vlanif1]ip address 172.16.1.2 25
[wa2]int vlan 2
[wa2-Vlanif2]
[wa2-Vlanif2]ip address 172.16.1.130 25 

网关备份

 [sw1]int vlan 1
[sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.126 
[sw1-Vlanif1]vrrp vrid 1 priority 105
[sw1-Vlanif1]vrrp vrid 1 track interface Ethernet0/0/5 reduced 10

[wa2-Vlanif2]int vlan 1
[wa2-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.126
[wa2-Vlanif1]int vlan 2
[wa2-Vlanif2]vrrp vrid 1 virtual-ip 172.16.1.254
[wa2-Vlanif2]vrrp vrid  1 track interface Ethernet 0/0/5 reduced 10 

 查询配置是否成功

 然后配置dhcp

[sw1]dhcp enable 
[sw1]ip pool v1 
[sw1-ip-pool-v1]network 172.16.1.0 
[sw1-ip-pool-v1]network 172.16.1.0 mask  25
[sw1-ip-pool-v1]gateway-list 172.16.1.126
[sw1-ip-pool-v1]dns-list 8.8.8.8
[sw1]int vlan 1   
[sw1-Vlanif1]dhcp select global 
[sw1-Vlanif1]int vlan 2
[sw1-Vlanif2]dhcp select global 

[sw1]ip pool v2
[sw1-ip-pool-v2]network 172.168.1.128 mask 25
[sw1-ip-pool-v2]gateway-list 172.16.1.254
[sw1-ip-pool-v2]dns-list 8.8.8.8

然后获取IP看配置是否成功 

 

 配置路由 

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip address 172.16.0.1 30
[r1-GigabitEthernet0/0/0]int g0/0/1
[r1-GigabitEthernet0/0/1]ip address 172.16.0.5 30

[sw1]vlan 20
[sw1-Vlanif20]ip address  172.16.0.2 30

[sw1]int e0/0/5
[sw1-Ethernet0/0/5]port l a
[sw1-Ethernet0/0/5]p d vlan 20

[wa2]vlan 20
[wa2-vlan20]q
[wa2]int e0/0/5
[wa2-Ethernet0/0/5]
[wa2-Ethernet0/0/5]port link-type access 
[wa2-Ethernet0/0/5]port default vlan 20
[wa2-Vlanif20]ip address 172.16.0.6 30

然后配置ospf再配置去往外网缺省和nat的就可以ping通了
