结构为er路由器，核心，现在vlan92上有一个92段的，核心现在两条外线，一条连锐捷连着教育网，另外一条连着er路由器连新的电信专线，客户说想要原本的教室网段改ip就可以用电信专线上网了，我就想到在核心上面的92段加个sub，192.168.8.1上去，之后做条策略路由，指向到路由器上面去嘛，然而现在核心交换机上面带源192.168.8.1ping192.168.10.1这个路由器ipping不通，路由器上面已经写了回包路由回来了，后来尝试在原本的教室电脑上面改ip，发现发现问题是，在终端，93段的ip可以ping通93.1，但是8.100却ping不通8.1。这个应该怎么排？我看了看核心上虽然有acl，但是没有应用，192.168.8.1是sub的，192.168.10.1是路由器的，192.168.10.2是核心交换机上与路由互联的。下面发一份core的配置文件，想问这是怎么回事？为什么会ping不通sub的ip。

8.100这个终端ip掩码配置没问题吧，你的配置没看出有问题
