使用vlans和无线路由器在多个公司路由器之间路由的数据包跟踪器帮助

Question

我仍然是一个包追踪器的新手(很抱歉，如果这已经被回答了)，我正在尝试在company1路由器上的两个vlans与company2路由器上的两个Lans之间切换，但是由于某种原因，当包被发送到ISP路由器时，它会去company3路由器而不是company1路由器，所以我不知道为什么(ps )。我已经集群了两个vlans和设置了ip路由)。另外，company4的无线路由器无法在局域网外切换，我想可能是因为无线路由器是其中一种方式，所以我尝试用普通路由器临时替换无线路由器，看看这是否是问题，但现在没有运气，所以我很难接受任何帮助。

Answer 1

每个路由器只有一个默认路由指向中间的ISP路由器。除非ISP路由器有固定的路由到每个公司路由器背后的所有子网，否则不会有任何数据包找到它们的方式。

同样，C4也不知道无线路由器后面的子网。任何注定(返回)到子网的数据包永远找不到它的方向。
