工业路由器必须使用分发规则决定适用哪一种?

文章目录 : 产品文章

  工业路由器收到IP包时,必须决定改数据包是否发给本工业TD-LTE路由器(应本地分发)或另一系统(应转发处理)。上述两种情况下可能同时发生,某些IP广播或IP多播可能同时要求本地分发及转发。工业路由器必须使用下面规则决定适用哪一种情况:

  1.未到期的源路由选项域是那些指针值没有超过源路由选项域中的最后条目。如果IP包包含一个未到期的源路由选项域,选项域中的指针应前移,直到指针超过该选项域中最后一个地址,或下一地址已不是该路由器的地址。

  2.下列情况,包被本地分发,不考虑转发:【4g无线路由器

  数据包的目的地地址完全匹配工业LTE路由器的某个IP地址;

  数据包的目的地地址是有限广播地址;

  数据包的目的地地址是IP多播地址,该地址不会成为转发目的地址(例如224.0.0.1或者244.0.0.2)且收到数据包的物理接口上相关联的逻辑接口至少一个工业EVDO路由器是目标多播组的成员。

  3.下列情况下包被转发及本地分发:

  数据包的目的地地址是IP广播地址,该地址指向至少一个的逻辑接口,但是不指向收到该数据包的物理接口上相关联的逻辑接口。

  数据包的目的地是IP多播地址,该地址允许成为转发目的地址(不像224.0.0.1和224.0.0.2)且收到数据包的物理接口上相关联的逻辑接口至少一个是目标多播组的成员。
