路由器由联通双链路,电信双链路接入,4个出接口全部为固定ip,由于运营商给的地址较多,所有在每个出接口下配有多个sub地址,然后四条缺省路由下一跳指到每条线路的网关地址,电信线路缺省路由优先级分别为60、61,联通线路缺省路由优先级为62、63;现在出现的情况是通过公网能ping通电信所有的出接口地址,联通1的出接口地址也能全部ping通,联通2出接口下的58.251.137.242无法ping通,但这个接口下其他的sub地址却可以ping通
4个出接口配置如下
联通1

最佳答案
看一下这个地址直接配在电脑上能不能ping通呢?
(0)
在电脑上是可以的,我觉得是路由的问题,我如果把联通1的出接口shutdown,那么联通2所有的地址就都能ping通,重启undo shutdown后,该地址就又不通了
那就不太清楚了,看看有没有其他大神
