一. 链路捆绑实现冗余功能实验1.在华为模拟器ensp上设置两个普通路由器，两个交换机，四台PC
先打开ensp ，新建2个路由器和2个pc用户，分别用网线连接,如下图
- 配置LSW1 LACP
配置lacp[SW1]lacp priority 1000 [SW1]int Eth-Trunk 1 [SW1-Eth-Trunk1]bpdu enable [SW1-Eth-Trunk1]mode lacp-static [SW1-Eth-Trunk1]max active-linknumber 2 [SW1-Eth-Trunk1]q [SW1]vlan batch 10 20 [SW1]int Eth-Trunk 1 [SW1-Eth-Trunk1]trunkport e 0/0/20 to 0/0/22 [SW1-Eth-Trunk1]p l t [SW1-Eth-Trunk1]p t a v a [SW1-Eth-Trunk1]un sh [SW1-Eth-Trunk1]dis eth-trunk 1 Least Active-linknumber: 1 Max Active-linknumber: 2 Ethernet0/0/20 Unselect 100M 32768 21 289 10100010 1 Ethernet0/0/21 Unselect 100M 32768 22 289 10100010 1 Ethernet0/0/22 Unselect 100M 32768 23 289 10100010 1 [SW1-Eth-Trunk1]dis int brief Eth-Trunk1 down down 0% 0% 0 0 Ethernet0/0/20 up up 0% 0% 0 0 Ethernet0/0/21 up up 0% 0% 0 0 Ethernet0/0/22 up up 0% 0% 0 0配置Trunk 2
[SW1]int Eth-Trunk 2 [SW1-Eth-Trunk2]trunkport g 0/0/1 to 0/0/2 [SW1-Eth-Trunk2]p l a [SW1-Eth-Trunk2]p d v 10 [SW1-Eth-Trunk2]un sh [SW1]dis eth-trunk 2 Eth-Trunk2 up up 0% 0% 0 0 GigabitEthernet0/0/1 up up 0% 0% 0 0 GigabitEthernet0/0/2 up up 0% 0% 0 0
配置接PC的连个口
[SW1-Eth-Trunk1]q
[SW1]int e0/0/1
[SW1-Ethernet0/0/1]p l a
[SW1-Ethernet0/0/1]p d v 10
[SW1-Ethernet0/0/1]un sh
[SW1-Ethernet0/0/1]int e0/0/2
[SW1-Ethernet0/0/2]p l a
[SW1-Ethernet0/0/2]p d v 20
[SW1-Ethernet0/0/2]undo sh- 配置LSW2
[SW2] int Eth-Trunk 1 [SW2Eth-Trunk1]bpdu enable [SW2Eth-Trunk1]mode lacp-static [SW2-Eth-Trunk1]trunkport e 0/0/20 to 0/0/22 [SW2-Eth-Trunk1]p l t [SW2-Eth-Trunk1]p t a v a [SW2-Eth-Trunk1]un sh [SW2-Eth-Trunk1]int Eth-Trunk 2 [SW2-Eth-Trunk2]trunkport g 0/0/1 to 0/0/2 [SW2-Eth-Trunk2]p l a [SW2-Eth-Trunk2]p d v 20 [SW2-Eth-Trunk2]un sh [SW2]int e0/0/1 [SW2-Ethernet0/0/1]p l a [SW2-Ethernet0/0/1]p d v 10 [SW2-Ethernet0/0/1]undo sh [SW2-Ethernet0/0/1]int e0/0/2 [SW2-Ethernet0/0/2]p l a [SW2-Ethernet0/0/2]p d v 20 [SW2-Ethernet0/0/2]un sh [SW2-Ethernet0/0/2]dis int brief Eth-Trunk1 up up 0% 0% 0 0 Ethernet0/0/20 up up 0% 0% 0 0 Ethernet0/0/21 up up 0% 0% 0 0 Ethernet0/0/22 up up 0% 0% 0 0 Eth-Trunk2 up up 0% 0% 0 0 GigabitEthernet0/0/1 up up 0% 0% 0 0 GigabitEthernet0/0/2 up up 0% 0% 0 04.配置R1
[R1]interface Eth-Trunk 1 [R1-Eth-Trunk1]trunkport g 0/0/2 to 0/0/3 [R1-Eth-Trunk1]ip add 12.0.0.1 30 [R1-Eth-Trunk1]un sh [R1-Eth-Trunk1]interface Eth-Trunk 2 [R1-Eth-Trunk2]trunkport g 0/0/0 to 0/0/1 [R1-Eth-Trunk2]ip add 192.168.10.1 24 [R1-Eth-Trunk2]un sh [R1-Eth-Trunk2]dis int brief Eth-Trunk1 up up 0% 0% 0 0 GigabitEthernet0/0/2 up up 0% 0% 0 0 GigabitEthernet0/0/3 up up 0% 0% 0 0 Eth-Trunk2 up up 0% 0% 0 0 GigabitEthernet0/0/0 up up 0% 0% 0 0 GigabitEthernet0/0/1 up up 0% 0% 0 0配置静态路由
[R1]ip route-static 192.168.20.0 24 12.0.0.2 [R1]ping 192.168.10.20 PING 192.168.10.20: 56 data bytes, press CTRL_C to break Reply from 192.168.10.20: bytes=56 Sequence=1 ttl=128 time=180 ms [R1]ping 192.168.10.10 PING 192.168.10.10: 56 data bytes, press CTRL_C to break Reply from 192.168.10.10: bytes=56 Sequence=1 ttl=128 time=140 ms Reply from 192.168.10.10: bytes=56 Sequence=2 ttl=128 time=60 ms5.配置R2
[R2]interface Eth-Trunk 1 [R2-Eth-Trunk1]trunkport g 0/0/2 to 0/0/3 [R2-Eth-Trunk1]ip add 12.0.0.2 30 [R2-Eth-Trunk1]un sh [R2-Eth-Trunk1]int eth-trunk 2 [R2-Eth-Trunk2]trunkport g 0/0/0 to 0/0/1 [R2-Eth-Trunk2]ip add 192.168.20.1 24 [R2-Eth-Trunk2]un sh [R2-Eth-Trunk2]ip route-static 192.168.10.0 24 12.0.0.1 [R2]ping 12.0.0.1 PING 12.0.0.1: 56 data bytes, press CTRL_C to break Reply from 12.0.0.1: bytes=56 Sequence=1 ttl=255 time=60 ms Reply from 12.0.0.1: bytes=56 Sequence=2 ttl=255 time=30 ms6.主机配置注意网关地址一定要填
如PC1 10.10网关时10.1
7.互通性测试
每台主机Ping 其他三台都能通，则ok.
