1.边界网关协议(BGP)：
在 BGP 中，使用传输控制协议。它是一种网状拓扑或设计。它通过交换路由信息的两个独立网络(自治系统或 AS)工作。两台路由器同意交换有关如何到达某些 IP 范围的信息。 BGP 使用传输控制协议 (TCP) 端口 179。
2. 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标的路由循环。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)性能较差且规模有限，即网络较小。使用 RIP 的主要优点是它使用 UDP(用户数据报协议)。边界网关协议 (BGP) 和路由信息协议 (RIP) 之间的区别：
| S.NO. | Border Gateway Protocol | Routing Information Protocol |
|---|---|---|
| 1. | BGP stands for Border Gateway Protocol. | RIP Stands for Routing Information Protocol. |
| 2. | It works on Best path algorithm. | RIP works on Bellman Ford algorithm. |
| 3. | It is basically used for very lager size organizations as compared to RIP. | It is basically used for smaller size organizations. |
| 4. | It is an external gateway protocol. | It is an industry standard dynamic routing protocol. |
| 5. | It is a more intelligent routing protocol than RIP. | It is not a very intelligent dynamic routing protocol. |
| 6. | The networks are classified as areas and tables. | The networks are classified as areas, sub areas, autonomous systems and backbone areas. |
| 7. | It calculates the metric in terms of Hop Count. | It calculates the metric in terms of Bandwidth. |
| 8. | It is hybrid type. | It is a Vector State type. |
| 9. | There is no such restriction on the hop count. | It allows a maximum of 15 hops. |
