RIP

RIP v1：为有类别路由协议，不支持VLSM和CIDR

             以广播的形式发送报文

             不支持验证

RIP v2：为无类别路由协议，支持VLSM，支持路由聚合与CIDR

             支持以广播或者组播（224.0.0.9）的形式发送报文

             支持明文验证和MD5密文验证

RIP是距离矢量路由选择协议

 

RIP的基本概念：

定期更新 30S

邻居

广播更新

全路由表更新

 

RIP度量值为跳数

最大跳数为15跳，16跳为不可达

RIP更新时间

每隔30秒发送路由更新消息，UDP520端口

RIP路由更新消息

发送整个路由表信息

什么是主类网络边界？

指的是两个不同的主类网络之间的路由网段

如图所示：

R2、R3就是跨越主类网络边界的路由器，R2连接了主类12网段和主类172网段，R3连接了主类12网段和主类172网段。
