ensp利用OSPF、LACP、DHCP实现虚拟机全网互通（PC1可以ping通PC5）

这个是我在学习OSPF、LACP、DHCP时做的一个综合性的实验，想把这个实验分享给学习网络的读者们

拓扑如图所示

配置如下

1.R1-R3各接口配置IP地址
1.1R1
[R1-GigabitEthernet0/0/1]ip address 10.1.12.1 24
[R1-GigabitEthernet0/0/0]ip address 192.168.1.254 24
1.2R2
[R2-GigabitEthernet0/0/0]ip address 10.1.12.2 24
[R2-GigabitEthernet0/0/1]ip address 10.1.23.1 24
1.3R3
[R3-GigabitEthernet0/0/1]ip address 10.1.23.2 24
[R3-GigabitEthernet0/0/1]ip address 172.16.1.254 24
2.R1-R3之间运行ospf网络
2.1R1
[R1]ospf 1 router-id 1.1.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]network 10.1.12.0 0.0.0.255
2.2R2
[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.1.12.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255
2.3R3
[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 172.16.1.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255
3.LSW1与LSW2之间使用基于LACP的链路聚合，设置最大活动接口数为2
并使G0/0/1和G0/0/3处于活动状态
3.1SW1
[SW1]interface Eth-Trunk 1
[SW1-Eth-Trunk1]mode lacp-static 
[SW1-Eth-Trunk1]qu
[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/5]eth-trunk 1
//其余2-4接口类似配置
[SW1]interface Eth-Trunk 1
[SW1-Eth-Trunk1]max active-linknumber 2
[SW1-Eth-Trunk1]qu
[SW1-GigabitEthernet0/0/1]lacp priority 100
[SW1-GigabitEthernet0/0/3]lacp priority 100
[SW1]display dhcp statistics
[SW1]display eth-trunk 1
3.2SW2
[SW2]interface Eth-Trunk 1
[SW2-Eth-Trunk1]mode lacp-static 
[SW2-Eth-Trunk1]qu
[SW2]interface GigabitEthernet 0/0/5
[SW2-GigabitEthernet0/0/5]eth-trunk 1
//其余6-8接口类似配置
[SW2]interface Eth-Trunk 1
[SW2-Eth-Trunk1]max active-linknumber 2
[SW2-Eth-Trunk1]qu
[SW2-GigabitEthernet0/0/5]lacp priority 100
[SW2-GigabitEthernet0/0/7]lacp priority 100
[SW2]display dhcp statistics
[SW2]display eth-trunk 1
4.PC1——PC4配置基于全局的DHCP，PC5配置基于接口的DHCP
，dns统一设置为8.8.8.8。并在全局DHCP中排除192.168.1.253的地址
提交结果
4.1R1
[R1]dhcp enable
[R1-GigabitEthernet0/0/0]ip address 192.168.1.254 24
[R1]ip pool 1    //创建地址池
[R1-ip-pool-1]network 192.168.1.0 mask 24  //选择可以分配的地址范围
[R1-ip-pool-1]gateway-list 192.168.1.254  //设置网关
[R1-ip-pool-1]dns-list 8.8.8.8  //设置DNS
[R1-GigabitEthernet0/0/0]dhcp select global 
4.2R3
[R3-GigabitEthernet0/0/1]ip address 172.16.1.254 24
[R3]dhcp enable
[R3-GigabitEthernet0/0/1]dhcp select interface //在接口下开启基于接口的DHCP
[R3-GigabitEthernet0/0/1]dhcp server dns-list 8.8.8.8 //配置DNS地址

结果显示如下
