基于rip协议的距离向量算法

收到相邻路由器（地址为X）的每一个rip报文 1，先修改此报文中的所有项目：将“下一跳”字段中的地址都改为X，并将所有的“距离”字段的值加1 2，对修改后的报文中的每一个项目，重复以下步骤 若项目中的目的网络不在路由表中，则将该项目添加到路由表中



否则，若下一跳字段给的路由器地址是同样的，则将收到的项目替换原路由表中的项目



否则，若收到的项目中的距离小于路由表中的距离，则进行更新



否则，设么也不做-Rip protocol based on distance vector algorithm receives the adjacent router (address X) rip each packet 1, the first to modify this message to all projects: the " next hop"　address fields are replaced by X, and all of the " distance"　field value plus 1　2, the modified packets of each item, repeat the following steps　if the project is not the purpose of network routing table, then add the item to the routing table in or, if the field to the next hop router address is the same, you will receive the items in the routing table to replace the original item or, if the item received is less than the distance from the routing table, then the Updated Otherwise, do not set Mody
