如下:
两台S6805为一个DRNI系统,两台S5560为另一个DRNI系统。四台设备交叉互联,配置DR口将四条链路配置为一个大的跨设备二层聚合。目前的问题是5560-01设备的vlan10地址172.16.1.117 ping不通S6805-01设备上的172.16.1.253和vrrp虚地址172.16.1.254. drni的ipp聚合口为bagg1024,6800使用xge1/0/33、1/0/34与5560的1/0/49、1、0/50的物理链路会连。68上的聚合口为bagg2,5560的聚合口为bagg1。
5560-01设备的vlan10地址172.16.1.117 ping不通S6805-01设备上的172.16.1.253和vrrp虚地址172.16.1.254;5560-02设备上ping对端6805-02设备的地址能通。
查看drni的状态是正常的:

在S5560上查看S6805-1的ARP发现学不到,查看debug arp信息,发现报文被丢弃:

设备全局和IPP口没有配置undo mac-address static source-check enable命令关闭报文入接口与静态MAC地址表项匹配检查功能。
因为DR系统中,主备很多配置都完全一样,需要在ipl链路上注意避免冲突,防止从主发往备的报文的源mac地址和目的网关的mac地址一样,被源mac检查丢掉了;可通过“display interface current-configuration Bridge-Aggregation IPP口对应的聚合口编号”来检查两个设备的DR口状态是否正常。
在S5560全局和S6805IPP接口(不同设备位置不一样,需参考配置指导)配上这个命令undo mac-address static source-check enable
