实验22_链路聚合合集_ENSP

1.二层链路聚合

---

#实搭拓扑图：

---

#具体操作：
##SW1:

[SW1]int eth-trunk 1 //创建捆绑组1
[SW1-Eth-Trunk1]interface GigabitEthernet0/0/1
[SW1-GigabitEthernet0/0/1]eth-trunk 1 //将gi0/0/1口加入捆绑组1
其他接口(2-4)同理,略

将捆绑之后的链路配置为trunk链路：
[SW1]int Eth-Trunk 1
[SW1-Eth-Trunk1]port li trunk 	
[SW1-Eth-Trunk1]port trunk allow-pass  vlan  all

---

##sw2:

[sw2]int Eth-Trunk 1	
[sw2-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/4
[sw2]int Eth-Trunk 1
[sw2-Eth-Trunk1]port li trunk 	
[sw2-Eth-Trunk1]port trunk allow-pass  vlan  all

---

2.三层链路聚合 路由器和路由器

---

#实搭拓扑图：

---

#具体操作：
##R1:

[R1]int Eth-Trunk 1
[R1-Eth-Trunk1]undo portswitch 	//将二层逻辑接口提升为三层接口
[R1-Eth-Trunk1]ip address 12.1.1.1 255.255.255.0
[R1-Eth-Trunk1]int g0/0/0
[R1-GigabitEthernet0/0/0]eth-trunk 1
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]eth-trunk 1

---

##R2:

[R2]interface Eth-Trunk 1
[R2-Eth-Trunk1]undo portswitch
[R2-Eth-Trunk1]ip address 12.1.1.2 24
[R2-Eth-Trunk1]int g0/0/0	
[R2-GigabitEthernet0/0/0]eth-trunk 1
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]eth-trunk 1

[SW1-GigabitEthernet0/0/2]int vlanif 10
[SW1-Vlanif10]ip address 12.1.1.2 24

5.LACP(推荐)

可以自定义备份链路，“灵活”,有协商报文

---

#实搭拓扑图：

---

#具体操作：
##SW1:

[SW1]int Eth-Trunk 1	
[SW1-Eth-Trunk1]mode lacp-static %该指令必须先配置，然后再向该捆绑组添加成员接口
[SW1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/4	

配置sw1 为主设备：
[SW1]lacp priority 50 %系统优先级默认是32768 ，数字越小越优先。
[SW1]int Eth-Trunk 1
[SW1-Eth-Trunk1]max active-linknumber 4 %指定最大活跃接口数量
[SW1-Eth-Trunk1]least active-linknumber 2 %最少活跃链路的数量，如果up链路少于2个则整条捆绑链路down 掉。
[SW1]int GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]lacp priority 10 %接口优先级，数字越小越被优先选用
[SW1-GigabitEthernet0/0/1]int gi0/0/2
[SW1-GigabitEthernet0/0/2]lacp priority 20
[SW1-GigabitEthernet0/0/2]int gi0/0/3
[SW1-GigabitEthernet0/0/3]lacp priority 30
[SW1-GigabitEthernet0/0/3]int gi0/0/4
[SW1-GigabitEthernet0/0/4]lacp priority 40
