HCIP---三层架构实验

一、实验要求

1.内网IP用172.16.0.0 /16合理分配
2.SW1/2之间互为备份
3.VRRP/STP/VLAN/TRUNK均使用
4.所有PC通过DHCP获取IP地址

调生成树:

[sw1]stp enable 	
[sw1]stp mode mstp 
[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 

[sw2]stp enable 
[sw2]stp mode mstp 
[sw2]stp region-configuration 
[sw2-mst-region]region-name a
[sw2-mst-region]instance 1 vlan 1
[sw2-mst-region]instance 2 vlan 2

调整根网桥:

[sw1]stp instance  1 root primary 
[sw1]stp instance 2 root secondary 

[sw2]stp instance 1 root secondary 
[sw2]stp instance  2 root primary 

在这里插入图片描述

[sw3]port-group group-member Ethernet 0/0/3 to Ethernet 0/0/4
[sw3-port-group]stp edged-port enable 
[sw3-Ethernet0/0/3]stp edged-port enable 
[sw3-Ethernet0/0/4]stp edged-port enable 

[sw4]port-group group-member Ethernet 0/0/3 to Ethernet 0/0/4
[sw4-port-group]stp edged-port enable 
[sw4-Ethernet0/0/3]stp edged-port enable 
[sw4-Ethernet0/0/4]stp edged-port enable 

做SVI:

[sw1]interface Vlanif 1
[sw1-Vlanif1]ip address 172.16.1.1 25
[sw1]interface Vlanif 2
[sw1-Vlanif2]ip address  172.16.1.129 25

[sw2]interface Vlanif 1
[sw2-Vlanif1]ip address 192.16.1.2 25
[sw2]interface Vlanif 2
[sw2-Vlanif2]ip address 172.16.1.130 25

在这里插入图片描述

做VRRP:

[sw1]interface Vlanif 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 GigabitEthernet 0/0/1 reduced 6
[sw1]interface Vlanif 2
[sw1-Vlanif2]vrrp vrid 1 virtual-ip 172.161.254

[sw2]interface Vlanif 1 
[sw2-Vlanif1]vrrp vrid 1 virtual-ip172.16.1.126
[sw2]interface Vlanif 2
[sw2-Vlanif2]vrrp vrid  2 virtual-ip 172.16.1.254
[sw2-Vlanif2]vrrp vrid 1 priority 105
[sw2-Vlanif2]vrrp vrid  1 track interface GigabitEthernet 0/0/1 reduced 6

做DHCP:

[sw1]ip pool v1
[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 114.114.114.114 8.8.8.8
[sw1]ip pool v2
[sw1-ip-pool-v2]network 172.16.1.128 mask 25
[sw1-ip-pool-v2]gateway-list 172.16.1.254
[sw1-ip-pool-v2]dns-list 114.114.114.114

[sw1]interface Vlanif 1
[sw1-Vlanif1]dhcp select global 
[sw1]interface Vlanif 2
[sw1-Vlanif2]dhcp select global 

sw2一样的做法

交换下边做完了 开始配置公网:

[r1]interface  g0/0/2
[r1-GigabitEthernet0/0/2]ip address 12.1.1.1 24
[r1-GigabitEthernet0/0/2]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


[isp]interface  g0/0/2
[isp-GigabitEthernet0/0/2]ip add 12.1.1.2 24
[isp-GigabitEthernet0/0/2]int l0
[isp-LoopBack0]ip add 6.6.6.6 24

在这里插入图片描述

[sw1]vlan 99
[sw1-vlan99]q	
[sw1]interface Vlanif 99
[sw1-Vlanif99]ip add 172.16.0.2 30
[sw1]interface g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type access 	
[sw1-GigabitEthernet0/0/1]port default vlan 99

[sw2]vlan 99
[sw2-vlan99]q
[sw2]interface Vlanif 99
[sw2-Vlanif99]ip address 172.16.0.6 30
[sw2-Vlanif99]q
[sw2]interface g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type access 
[sw2-GigabitEthernet0/0/1]port default vlan 99

核心层跑ospf,但是无法汇总:

[r1]ospf 1 router-id 1.1.1.1
[r1-ospf-1]area 0 
[r1-ospf-1-area-0.0.0.0]network 172.16.0.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 172.16.0.5 0.0.0.0

[sw1]ospf 1 router-id 2.2.2.2	
[sw1-ospf-1]area 0
[sw1-ospf-1-area-0.0.0.0]network 172.16.0.2 0.0.0.0
[sw1-ospf-1]area 1
[sw1-ospf-1-area-0.0.0.1]
[sw1-ospf-1-area-0.0.0.1]network 172.16.1.1 0.0.0.0	
[sw1-ospf-1-area-0.0.0.1]network 172.16.1.129 0.0.0.0

[sw2]ospf 1 router-id 3.3.3.3
[sw2-ospf-1]area 0
[sw2-ospf-1-area-0.0.0.0]network  172.16.0.6 0.0.0.0
[sw2-ospf-1]area 1
[sw2-ospf-1-area-0.0.0.1]network 172.16.1.2 0.0.0.0
[sw2-ospf-1-area-0.0.0.1]network 172.16.1.130 0.0.0.0

[sw1-ospf-1]silent-interface all 
[sw1-ospf-1]undo silent-interface GigabitEthernet 0/0/1
[sw1-ospf-1]undo silent-interface Eth-Trunk 0
[sw1-ospf-1]undo silent-interface Vlanif 1
[sw1-ospf-1]undo silent-interface Vlanif 99
[sw1-ospf-1-area-0.0.0.1]abr-summary 172.16.1.0 255.255.255.0

[sw2-ospf-1]silent-interface GigabitEthernet 0/0/2
[sw2-ospf-1]silent-interface GigabitEthernet 0/0/3
[sw2-ospf-1]silent-interface Vlanif 2
[sw2-ospf-1-area-0.0.0.1]abr-summary 172.16.1.0 255.255.255.0

最后做缺省和nat:

[r1]ip route-static 0.0.0.0 0 12.1.1.2
[r1]ospf 1
[r1-ospf-1]default-route-advertise
[r1-ospf-1]q
[r1]acl 2000
[r1-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r1]interface GigabitEthernet 0/0/2
[r1-GigabitEthernet0/0/2]nat outbound 2000

防环;

[sw1]ip route-static 172.16.1.0 24 NULL 0
[sw2]ip route-static 172.16.1.0 24 NULL 0

四、测试
