【网络-实验】rip最大有效跳数15

365bet导航 admin 2025-10-09 04:11:07

相信给位网工大拿学习RIP时都看到过这样一句话：

RIP 使用跳数（Hop Count）来衡量到达目的网络的距离。在RIP中，路由器到与它直接相连网络的跳数为0，每经过一个路由器后跳数加1，

其余依此类推。为限制收敛时间，RIP规定metric取值0~15之间的整数，大于或等于16的跳数被定义为无穷大，即目的网络或主机不可达。

换成人话说：跳数不能超过16。

今天做个实验验证下，网络拓扑图如下：连线的顺序为0口连接上一台设备，1口连接下一台设备。

rip版本为2

PS:注意哦，是17台路由器串联而不是16台路由器串联。

16台串联才15跳

17台串联才能达到16跳

我们在AR16查看rip路由

192.168.1.0/24 RIP 100 15 D 116.1.1.1 GigabitEthernet0/0/0

RIP routing table status :

可以看到可以学到去往192.168.1.0/24网段的路由，开销为15。

我们再到AR17上查看RIP路由

116.1.1.0/24 RIP 100 1 D 117.1.1.1 GigabitEthernet0/0/0

RIP routing table status :

Destinations : 0 Routes : 0

可以看到没有学到去往192.168.1.0/24网段的路由。

原因为：AR16学到的路由开销为15，发出时加1，变成16。AR17收到后发现开销为16，既无效路由，自然不会添加到自己的路由表里。

所以我们可以得出一个结论:运行RIP路由协议的路由器最大串联数量为15，超过后将会丢失路由。
