什么是工业4g路由器RIPv2认证

文章目录 : 产品文章

  工业4g路由器

  1.RIPv2认证

  RIPv2增加了对发送响应帧设备的认证功能。由于响应帧用作传送网络路由信息,对响应帧作认证可以防止在全网传播虚假路由表。响应帧使用一个工业全网通路由器记录空间来承载。带认证的响应帧的第一个AFI字段被设置成0xFFFF来区别路由记录。所以带认证的响应帧中最大路由条数为24。认证记录中路由标签被作为认证类型。后24字节可以存放明文口令或MD5散列后的口令。

  RIPv2认证并没有对承载工业FDD-LTE路由器信息的加密或数字签名,所以使用RIPv2认证的网络仍然很容易受到攻击。

  2.子网掩码

  子网掩码字段因适应网络支持子网需求而产生。RIPv2在地址字段后分配4字节的空间存储子网掩码。RIPv2使用地址字段和子网掩码字段区分网络,子网或主机。

  3.下一跳标识

  使用下一跳标识,RIPv2可以通过防止不必要的跳数而使转发更高效。该字段通常用在某一共享介质网络上不是所有设备都运行RIP的情况。当下一跳字段为0.0.0.0时,下一跳是发送路由信息的工业TD-LTE路由器。当下一跳字段为其他值时,下一跳为该地址所指向的设备。该地址必须由路由设备直接可达。如果接收路由的设备不能直接到达下一跳字段所指向的地址,则下一跳字段作0.0.0.0处理。
