工业路由器动态的NAT分类_路由表

文章目录 : 产品文章

  IP地址:在自治系统中具有唯一性,且是个逻辑地址。

  私有地址:免费给私有网络使用的地址,用于表示私有网络中的网络与主机,只在同一管理域,自治系统域中是唯一的。工业级全网路由器资源是可以在不同的管理域中充分使用。在Internet,不提供网络寻址。

  NAT分类:【工业路由器

  静态的nat

  实现一对一的对应关系,永久绑定一个私有地址与公有地址的映射关系。

  通常用于工业全网通路由器网络内部的某项服务需要互联网络直接访问时,使用静态的nat

  动态的NAT【4g无线路由器

  实现工业级全网通路由器动态的一对一映射关系,通常当私有网络用户。但同一时刻访问资源较少时可以使用。或者全网通工业路由器没有特殊要求需要一对一的永久绑定时,可以使用。

  端口NAT【4g路由器

  是节省IP地址的一种方法,使用的是多个本地地址对应一个本地全局地址,通过不同的通信接口来标识不同的本地地址。是目前全网通工业级路由器应用最广泛的一个,又叫地址复用技术。

  全网工业路由器路由信息协议–路由表

  1.使用udp520端口来工作,并且rip是应用层协议和bgp一样。

  2.消息类型:请求消息和应答消息。

  3.更新的方式:版本1是广播更新版本二是组播224.0.0.9

  4.是距离矢量路由选择协议的一种,(*定期将工业路由器路由表复制给邻居,并且进行矢量堆加)。

  5.工作的度量值为跳数,最大可达跳数为15跳,16跳为不可达,对于工业级路由器而言,16跳为无穷大。

  6.更新时间,每30秒发送更新,180秒保持失效,240秒删除失效记录,又称刷新时间。

  7.有被称为传闻式路由协议,所以会出现环路,【4g无线路由器
