华为单臂路由、DHCP、LACP模式链路捆绑、二层与三层链路捆绑!

◆◆实验拓扑◆◆

◆◆实验需求◆◆

1、C1与C3属于vlan10，C2与C4属于vlan20

2、SW1与SW2之间使用LACP模式链路捆绑，活动接口为2个

3、SW1与R1之间进行链路捆绑

4、VLAN 10 与 VLAN 20 通过DHCP自动获取IP地址

5、在R1上配置单臂路由使全网互通

vlan10 IP：192.168.10.0/24

vlan20 IP：192.168.20.0/24

SW1配置：

system-view //进入系统视图

[SW1]vlan batch 10 20 //创建vlan

[SW1]inter e0/0/1 //进接口

[SW1-Ethernet0/0/1]port hybrid pvid vlan 10 //为进来的数据包加vlan10标签

[SW1-Ethernet0/0/1]port hybrid untagged vlan 10 //将接口以untagged方式加入vlan10

[SW1-Ethernet0/0/1]quit

[SW1]inter e0/0/2

[SW1-Ethernet0/0/2]port hybrid pvid vlan 20

[SW1-Ethernet0/0/2]port hybrid untagged vlan 20

[SW1-Ethernet0/0/2]quit

[SW1]lacp priority 100 //配置系统优先级为100

[SW1]inter eth-trunk 1 //进入eth-trunk 1

[SW1-Eth-Trunk1]mode lacp-static //设置为lacp模式

[SW1-Eth-Trunk1]max active-linknumber 2 //设置活动接口为2

[SW1-Eth-Trunk1]port hybrid tagged vlan 10 20 //将接口以tagged方式加入到vlan10和vlan20,设置中继

[SW1-Eth-Trunk1]quit

[SW1]interface e0/0/10 //进接口

[SW1-Ethernet0/0/10]eth-trunk 1 //将接口加入eth-trunk

[SW1-Ethernet0/0/10]lacp priority 100 //设置接口优先级为100，默认为32768

[SW1-Ethernet0/0/10]inter e0/0/11

[SW1-Ethernet0/0/11]eth-trunk 1

[SW1-Ethernet0/0/11]inter e0/0/12

[SW1-Ethernet0/0/12]eth-trunk 1

[SW1-Ethernet0/0/12]quit

[SW1]interface Eth-Trunk 2 //进入eth-trunk 2

[SW1-Eth-Trunk2]trunkport GigabitEthernet 0/0/1 0/0/2 //将接口加入到eth-trunk中

[SW1-Eth-Trunk2]port hybrid tagged vlan 10 20 //将接口以tagged方式加入到vlan10和vlan20

SW2配置:

system-view

[SW2]vlan batch 10 20

[SW2]inter e0/0/3

[SW2-Ethernet0/0/3]port hybrid pvid vlan 10

[SW2-Ethernet0/0/3]port hybrid untagged vlan 10

[SW2-Ethernet0/0/3]quit

[SW2]interface e0/0/4

[SW2-Ethernet0/0/4]port hybrid pvid vlan 20

[SW2-Ethernet0/0/4]port hybrid untagged vlan 20

[SW2-Ethernet0/0/4]quit

[SW2]interface Eth-trunk 1

[SW2-Eth-Trunk1]mode lacp-static

[SW2-Eth-Trunk1]max active-linknumber 2

[SW2-Eth-Trunk1]trunkport Ethernet 0/0/10 to 0/0/12

[SW2-Eth-Trunk1]port hybrid tagged vlan 10 20

通过display eth-trunk 1 查看端口信息，发现优先级高的e0/0/10,e0/0/11接口被选中为活动接口优先级低的未被

◆◆在SW1上关闭一个端口SW1◆◆

[SW1]interface e0/0/10

[SW1-Ethernet0/0/10]shutdown

会发现0/0/10接口关闭了以后 0/0/12接口自动补上了

R1配置：

system-view

[R1]dhcp enable

[R1]interface Eth-Trunk 1 //进入eth-trunk 1

[R1-Eth-Trunk1]undo portswitch //转换三层口，默认eth-trunk是二层口路由是三层端口要把接口转换成三层接口才可以捆绑

[R1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 0/0/2 //将接口加入eth-trunk

[R1]interface Eth-Trunk 1.10 //进入子接口

[R1-Eth-Trunk1.10]dot1q termination vid 10 //封装dot1q，设置为vlan10的网关

[R1-Eth-Trunk1.10]ip address 192.168.10.1 24 //配置接口IP

[R1-Eth-Trunk1.10]arp broadcast enable //开启ARP广播

[R1-Eth-Trunk1.10]dhcp select interface //采用接口地址池的DHCP功能

[R1-Eth-Trunk1.10]inter eth-trunk 1.20

[R1-Eth-Trunk1.20]dot ter vid 20

[R1-Eth-Trunk1.20]ip add 192.168.20.1 24

[R1-Eth-Trunk1.20]a b e

[R1-Eth-Trunk1.20]dhcp sel int

用PC自动获取DHCP

C2获取

C3获取

C4获取

C1去测试，全网互通
