CE系列交换机M-LAG与Cisco vPC对接示例
适用产品和版本
CE系列交换机V200R005C10或更高版本。
组网需求
如图2-11所示，左侧为Cisco设备组建的网络，右侧为华为设备组建的网络，两个网络之间通过DCI Leaf互联。Cisco侧两台DCI Leaf组建vPC，华为侧两台DCI Leaf组建M-LAG，vPC与M-LAG之间通过跨设备链路聚合实现对接。
配置思路
- 配置Cisco侧的Leaf1、Leaf2交换机组建vPC，并创建跨设备链路聚合组。
- 配置华为侧的Leaf3、Leaf4交换机组建M-LAG，并创建跨设备链路聚合组。
操作步骤
- 配置Leaf1、Leaf2组建vPC，并创建跨设备链路聚合组。以下为Leaf1和Leaf2的相关配置。
Leaf1# vpc domain 1 //配置vPC域 role priority 10 peer-keepalive destination 10.10.1.2 source 10.10.1.1 auto-recovery interface port-channel1 //配置Peer-link switchport switchport mode trunk switchport trunk allowed vlan 100 spanning-tree port type network vpc peer-link interface port-channel10 //配置互联的链路聚合组 switchport switchport mode trunk switchport trunk allowed vlan 100 //放通互通VLAN vpc 10 interface Ethernet8/1 //将端口加入Peer-link switchport switchport mode trunk switchport trunk allowed vlan 100 channel-group 1 mode active no shutdown interface Ethernet8/2 switchport switchport mode trunk switchport trunk allowed vlan 100 channel-group 1 mode active no shutdown interface Ethernet8/3 //将端口加入DCI互联的链路聚合组 switchport switchport mode trunk switchport trunk allowed vlan 100 channel-group 10 mode active no shutdown interface Ethernet8/4 switchport switchport mode trunk switchport trunk allowed vlan 100 channel-group 10 mode active no shutdown

- 配置Leaf3、Leaf4组建M-LAG，并创建跨设备链路聚合组。以下为Leaf3和Leaf4的相关配置。
