E-trunk實驗配置

實驗說明：

PE兩臺交換機要三層可達，兩臺交換機使用E-trunk鏈接，都劃分到VLAN1裏面
設備CE：Eth-reunk 10
設備PE1：Eth-trunk 20
設備PE3：Eth-trunk 30

配置PE1和PE2三層IP可達

PE1配置接口和VLANIF

<Huawei>system-view     //進入全局配置模式
[Huawei]undo info-center enable     //關閉信息告警提示
[Huawei]sysname PE1     //更名
[PE1]interface g0/0/1     //進入接口
[PE1-GigabitEthernet0/0/1]port link-type access     //配置爲access鏈路，VLAN1默認爲本徵VLAN    
[PE1-GigabitEthernet0/0/1]quit     //退出
[PE1]interface vlanif1     //配置VLANIF1
[PE1-Vlanif1]ip address 10.1.1.1 255.255.255.0     //設置IP地址
[PE1-Vlanif1]quit     //退出
[PE1]

PE2配置接口和VLANIF

<Huawei>system-view     //進入全局配置模式 
[Huawei]undo info-center enable     //關閉信息告警提示 
[Huawei]sysname PE2     //更名
[PE2]interface g0/0/1     //進入接口
[PE2-GigabitEthernet0/0/1]port link-type access     //配置爲access鏈路，VLAN1默認爲本徵VLAN     
[PE2-GigabitEthernet0/0/1]quit     //退出
[PE2]interface vlanif1
[PE2-Vlanif1]ip address 10.1.1.2 255.255.255.0     //設置IP地址
[PE2-Vlanif1]quit     //退出
[PE2]

PE1測試是否能夠ping通PE 2設備

[PE1]ping 10.1.1.2     //測試ping PE2設備
  PING 10.1.1.2: 56  data bytes, press CTRL_C to break
    Reply from 10.1.1.2: bytes=56 Sequence=1 ttl=255 time=80 ms

DE配置Eth-trunk

<Huawei>system-view     //進入全局配置模式  
[Huawei]undo info-center enable     //關閉信息告警提示  
[Huawei]sysname CE     //更名
[CE]interface Eth-Trunk 10     //配置Eth-trunk10
[CE-Eth-Trunk10]mode lacp-static     //必須配置靜態 
[CE-Eth-Trunk10]trunkport GigabitEthernet 0/0/2 to 0/0/5     //將上面兩個設備當成一個設備，配置4條鏈路的捆綁
[CE-Eth-Trunk10]quit     //退出
[CE]

PE1和PE2同時配置：虛擬一個ID和優先級，讓下面設備（CE）認爲是一個設備

PE1配置MAC地址和優先級

[PE1]lacp e-trunk system-id 0000-0102-0304     //配置MAC地址
[PE1]lacp e-trunk priority 32768     //配置優先級

PE2配置MAC地址和優先級

[PE2]lacp e-trunk system-id 0000-0102-0304     //配置MAC地址
[PE2]lacp e-trunk priority 32768     //配置優先級

注：兩臺設備的MAC地址和優先級要一致

配置兩臺設備的主備

PE1配置E-trunk爲主設備

[PE1]e-trunk 1     //配置E-trunk 1
[PE1-e-trunk-1]priority 99     //越小越優先，默認100，用來在PE1和PE2之間競爭主備，備設備要down接口
[PE1-e-trunk-1]peer-address 10.1.1.2 source-address 10.1.1.1     //指定對端IP地址和本身的IP地址
[PE1-e-trunk-1]quit     //退出
[PE1]

PE2配置E-trunk爲備設備

[PE2]e-trunk 1     //配置E-trunk 1    
[PE2-e-trunk-1]peer-address 10.1.1.1 source-address 10.1.1.2     //指定對端IP地址和本身的IP地址
[PE2-e-trunk-1]quit     //退出
[PE2]

配置兩臺設備的E-trunk鏈接

PE1配置鏈接對端PE2設備

[PE1]interface Eth-Trunk 20     //本端20，對端30，也能夠都同樣
[PE1-Eth-Trunk20]mode lacp-static     //必須配置靜態
[PE1-Eth-Trunk20]trunkport g0/0/2     //捆綁G0/0/2鏈路  
[PE1-Eth-Trunk20]trunkport g0/0/3     //捆綁G0/0/3鏈路  
[PE1-Eth-Trunk20]e-trunk 1 remote-eth-trunk 30     //關聯E-trunk 1，remote-eth-trunk 30是對端Eth-trunk30
[PE1-Eth-Trunk20]quit     //退出
[PE1]

PE2配置鏈接對端PE1設備

[PE2]interface Eth-Trunk 30     //本端30，對端20，也能夠都同樣
[PE2-Eth-Trunk30]mode lacp-static     //必須配置靜態 
[PE2-Eth-Trunk30]trunkport g0/0/4     //捆綁G0/0/4鏈路  
[PE2-Eth-Trunk30]trunkport g0/0/5     //捆綁G0/0/5鏈路  
[PE2-Eth-Trunk30]e-trunk 1 remote-eth-trunk 20     //關聯E-trunk 1，remote-eth-trunk 30是對端Eth-trunk20
[PE2-Eth-Trunk30]quit     //退出
[PE2]

注：若是對端的Eth-trunk同樣的話，不用配置trmote-eth-trunk X
