网络拓扑变得越复杂工业路由器必须进行过滤

文章目录 : 产品文章

当网络拓扑变得越复杂时,越需要对复杂的路由进行过滤,因此路由器应对每个路由协议分别提供:4g路由器

1.从哪一逻辑端口或工业4G路由器可以接收路由信息,哪些路由可以信任;

2.哪些路由将通过哪个逻辑接口来发送;

3.路由信息将发送到哪个路由器。

在许多情况下,需要将从其他工业级路由器上收到的路由信息赋予可信任度。工业EVDO路由器可以指定:对收到的每条路由赋予可信度或优先级。无论每个路由所关联的路由度量如何,赋予高可信度的路由将优先选择。

如果工业路由器支持赋予优先级值,路由器不允许传播不作为第一方信息选择的路由。如果路由器使用的路由协议不支持区分第一方与第三方信息。路由器不能传播任何不能优先选择的路由。

如果路由器不使用某路由信息中的路由,则工业TD-LTE路由器不能传播给其他路由器。
