实验二十四：MP协议

1、实验二十四：MP协议一、 理论基础1、 MP简介MP是the PPP Multilink protocol的缩写，是人们出于增加带宽的考虑，将多条PPP链路捆绑起来，从而达到增加带宽的目的。MP协议能够对大的报文进行分片，分片将在多个PPP链路上送到同一个目的地，从而减少大报文的传送时间。Multilink PPP允许将报文分片，分片将从多个点对点的链路送到同一个目的地，多链路捆绑有两个条件：只要两个链路的Endpoint Discriminator和用户完全相符合时，才能对两个链路进行捆绑。这就意味着当验证完成后，才能真正完成MP协商过程。MP不会导致链路的拆除。如果配置了MP，两个链路不符

2、合MP条件，则会建立一条新的MP通道，这同时也表明允许MP为单链路。MP的捆绑是完全依照用户进行的，只要相同的用户才能进行捆绑。如一端配置了MP，另一端不支持或未配置成MP，则建立起来的链路为非MP链路。2、MP的工作进程(1)检测对端是否工作在MP方式。首先和对端进行LCP协商，协商过程中，除了协商一般的LCP参数外，还验证对端接口是否也工作在MP方式下。如果对端不工作在MP方式下，则在LCP协商成功后，进行NCP协商步骤，不进行MP捆绑。(2)将接口捆绑至虚模板接口。有两种方法可以将接口捆绑至虚模板接口：直接捆绑和根据用户名或终端标识符捆绑。直接捆绑是指不检测PPP接口的用户名和终端标识符

3、，直接将接口捆绑至指定的虚模板接口。根据用户名或终端标识符捆绑是指根据PPP验证的用户名或接口的终端标识符将接口捆绑至虚模板接口。(3)进行NCP协商等操作。PPP接口被捆绑至虚模板接口之后，将根据虚模板接口的各项NCP参数（如IP地址等）进行NCP协商，物理接口配置的NCP参数不起作用。NCP协商通过后，即可建立MP链路，用更大的带宽传输数据。二、 实验案例MP的配置1、实验拓扑结构图 2、配置说明：Router1的Ip地址： 192.168.100.1 子网掩码：255.255.255.0Router2的Ip地址： 192.168.100.2 子网掩码：255.255.255.03、 具体
