链路聚合实现冗余功能综合实验

链路聚合实现冗余功能综合实验

1.实验环境

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

2.配置LSW1 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             

Operate status: down    Number Of Up Port In Trunk: 0

 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 ms

5.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 ms

6.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.
