RIP 和 OSPF 的区别

1. 路由信息协议(RIP)：
RIP 代表路由信息协议，其中距离矢量路由协议用于数据/数据包传输。在路由信息协议 (RIP) 中，最大跳数为 15，因为它可以防止从源到目的地的路由循环。使用水平分割、路由中毒和抑制等机制来防止不正确或错误的路由信息。 Sally Floyd 和 Van Jacobson [1994] 建议，如果计时器没有轻微的随机化，计时器就会同步超时。与其他路由协议相比，RIP(路由信息协议)性能较差且限制规模，即小型网络。使用 RIP 的主要优点是它使用 UDP(用户数据报协议)。

2. 开放最短路径优先(OSPF)：
OSPF 代表开放最短路径优先，它使用链路状态路由算法。使用路由器中可用的链路状态信息，它构建拓扑，其中拓扑确定路由决策的路由表。它支持可变长度子网掩码和无类别域间路由寻址模型。由于它使用 Dijkstra 算法，因此它计算每条路线的最短路径树。 OSPF(开放最短路径优先)的主要优点是它自己处理错误检测，并使用多播寻址在广播域中进行路由。

RIP 和 OSPF 的区别

SR.NO	RIP	OSPF
1	RIP Stands for Routing Information Protocol.	OSPF stands for Open Shortest Path First.
2	RIP works on Bellman Ford algorithm.	OSPF works on Dijkstra algorithm.
3	It is a Distance Vector protocol and it uses the distance or hops count to determine the transmission path.	It is a link state protocol and it analyzes different sources like the speed, cost and path congestion while identifying the shortest path.
4	It is basically use for smaller size organization.	It is basically use for larger size organization in the network.
5	It allows a maximum of 15 hops.	There is no such restriction on the hop count.
6	It is not a more intelligent dynamic routing protocol.	It is a more intelligent routing protocol than RIP.
7	The networks are classified as areas and tables here.	The networks are classified as areas, sub areas, autonomous systems and backbone areas here.
8	Its administrative distance is 120.	Its administrative distance is 110.
9	RIP uses UDP(User Datagram Protocol) Protocol.	OSPF works for IP(Internet Protocol) Protocol.
10	It calculates the metric in terms of Hop Count.	It calculates the metric in terms of bandwidth.
