最佳答案
您好，请知：
1、可尝试将vlan 351给shutdown后看下是否能PING通，如果还能PING通，就远程登陆10.50.49.254这台设备查看是否有IP地址的冲突。
2、同时也有可能出现了物理环路，需要通过插拔线路或者关闭端口逐步排查。
3、如果VLAN 351是业务VLAN，建议业务VLAN都设置为OSPF静默接口。

你好，我在网络中没有发现冲突的ID的IP地址呢，每台设备都不一样的

debug看下，有可能是从本设备发出来，又收到的，就有环路的可能，或者把业务端口静默，环路还是要注意

其它ospf路由器 没有个这个日志，就一台有

看下10.50.49.254 这个地址在哪个设备上，这台设备的Vlan-interface351的IP地址又是多少。如果是在同一台设备，说明网络有环，如果不是同一台设备说明应该是冲突了。

10.50.49.254是VLAN351下面的vlan的IP地址，作为终端网关的
那说明网络有环路了，自己发出的报文自己又收到了，需要检查网络环境。
都是在核心6800三层交换机上面
