CCNA实验(3) -- RIP

RIP协议分为版本1和版本2，均具备以下特征：
1.是距离向量路由协议
2.使用跳数(Hop Count)作为度量值
3.默认路由更新周期为30秒
4.管理距离(AD)为120
5.支持触发更新
6.最大跳数为15跳
7.支持等价路径，默认4跳，最大6条
8.使用UDP520端口进行路由更新

RIPv1：
1.在路由更新过程中不携带子网信息
2.不提供认证
3.不支持VLSM和CIDR
4.采用广播更新
5.有类(Classful)路由协议

RIPv2：
1.在路由更新过程中携带子网信息
2.提供明文和MD5认证
3.支持VLSM和CIDR
4.采用组播(224.0.0.9)更新
5.无类(Classless)路由协议

1.RIPv1
2.RIPv2
3.RIPv1与RIPv2兼容
4.在接口上禁止运行RIP
5.RIPv2单播更新
6.RIPv2自动汇总
7.RIPv2手动汇总
8.RIPv2产生默认路由
9.RIPv2明文认证
10.RIPv2 MD5认证
11.RIP过滤路由
