配置说明 MC-LAG是一种实现跨设备链路聚合的机制，能够实现多台设备间的链路聚合，从而把链路可靠性从单板级提高到了设备级，组成双活系统。 MC-LAG典型组网如图1所示： 图1 MC-LAG典型组网示意图
配置思路
- 创建SmartGroup及配置peerlink链路
- 在peerlink上配置静态路由，使S1和S2之间loopback地址可达
- S1和S2之间配置LDP协议，用来同步MC-LAG数据
- S1和S2之间再配置一条三层链路用来进行keepalive保活和协商
- 配置MC-LAG成员及协商参数
-
配置双活系统虚MAC
配置过程
本示例使用IPv4和IPv6双栈，具体配置信息如下：
-
创建smartgroup1024并配置为peerlink链路。
S1的配置：
S1(config)#interface smartgroup1024 S1(config-if-smartgroup1024)#exit S1(config)#lacp S1(config-lacp)#interface smartgroup1024 S1(config-lacp-sg-if-smartgroup1024)#lacp mode 802.3ad S1(config-lacp-sg-if-smartgroup1024)#exit S1(config-lacp)#interface xgei-0/3/0/47 S1(config-lacp-member-if-xgei-0/3/0/47)#smartgroup 1024 mode active S1(config-lacp-member-if-xgei-0/3/0/47)#exit S1(config-lacp)#interface xgei-0/3/0/48 S1(config-lacp-member-if-xgei-0/3/0/48)#smartgroup 1024 mode active S1(config-lacp-member-if-xgei-0/3/0/48)#exit S1(config-lacp)#exit S1(config)#lacp S1(config-lacp)#lacp peer-link smartgroup1024 S1(config-lacp)#exit S1(config)#
