1.路由信息协议(RIP)：
在RIP中，距离矢量路由(DVR)协议用于数据/数据包传输。在路由信息协议(RIP)中，最大跃点数为15，因为它可以防止从源到目标的路由环路。使用诸如水平分割，路由中毒和保持所有权之类的机制来防止错误或错误的路由信息。 Sally Floyd和Van Jacobson [1994]建议，在不对计时器进行轻微随机化的情况下，计时器会随着时间的推移而同步。与其他路由协议相比，RIP较差并且限制了规模，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.增强的内部网关协议(EIGRP)：
EIGRP代表允许路由器与同一区域内的相邻路由器共享信息。不需要将全部信息发送到相邻路由器，而是共享所需的信息，这减少了工作量和需要传输的数据量。它是由CISCO系统设计的，只能在CISCO路由器中使用，但是在2013年它成为开源的，因此可以在其他路由器中使用。邻居表和拓扑表由EIGRP维护。
RIP和EIGRP之间的区别：
| SR.NO | RIP | EIGRP |
|---|---|---|
| 1. | RIP stands for Routing Information Protocol. | EIGRP stands for Enhanced Interior Gateway Routing Protocol. |
| 2. | RIP works on Bellman Ford algorithm. | EIGRP works on DUAL(Diffusing Update Algorithm) Algorithm. |
| 3. | It is a industry standard dynamic routing protocol. | It is a Cisco standard routing protocol. |
| 4. | It is basically use for smaller size organization. | It is basically use for lager size organization as compared to RIP. |
| 5. | RIP is a distance vector protocol. | EIGRP is derived from Integrated Gateway Routing Protocol. |
| 6. | It allow maximum hop count upto 15. | It allow maximum hop count upto 255. |
| 7. | It’s administrative distance is 120. | It’s administrative distance is 90. |
| 8. | It is not a more intelligent dynamic routing protocol. | It is a more intelligent routing protocol than RIP. |
| 9. | It calculates the metric in terms of Hop Count. | It calculates the metric in terms of bandwidth and delay. |
| 10. | RIP routing protocol creates two table in the router: Routing Table, and Topology Table. | EIGRP routing protocol creates three table In the router: Neighbor Table, Topology Table, and Routing Table. |
