RIPv1和RIPv2之间的区别

1. RIPv1：
RIPv1使用分类路由。定期路由更新不携带子网信息，缺少对可变长度子网掩码(VLSM)的支持。此限制使得不可能在同一网络类中拥有不同大小的子网。换句话说，网络类别中的所有子网都必须具有相同的大小。还不支持路由器身份验证，这使得RIP容易受到各种攻击。

2. RIPv2：
RIPv2是RFC 1723中定义的无类距离矢量路由协议。作为无类路由协议，它意味着在路由更新中包括子网掩码和网络地址。

由于RIPv1的不足，RIP版本2(RIPv2)于1993年开发，具有支持子网信息和支持无类域间路由(CIDR)的能力。

RIPv1和RIPv2之间的区别：
