2、小跳数作为路由选择的度量标准，而不是在链路的带宽和延迟的基础上进行选择。RIP是为小型网络设计的。它的最大跳数为15跳，16跳为无穷远，只能应用在中小型网络中。RIPv1是一种有类路由协议，不支持不连续子网设计。RIP周期进行路由更新，将路由表广播给邻居路由器，广播周期为30秒。RIP的管理距离为120。第3页/共66页6.1.1 RIP概述（续）RIPv2与RIPv1不同的特点：RIPv2（RFC 1723）是RIPv1的扩展版本。在RIPv2的消息包中包含了子网掩码信息。在RIPv2中，更新消息发送到多播地址224.0.0.9。RIPv2可以关闭自动汇总特性。第4页/共66页6.1.1 R
