在本节中，我们将讨论域内路由是如何从域间路由不同。域内是路由算法仅在域内工作的任何协议，另一方面，域间是路由算法在域内和域之间工作的任何协议。
让我们看看域内和域间之间的区别：
| S.No | Intradomain Routing | Interdomain Routing |
|---|---|---|
| 1. | Routing algorithm works only within domains. | Routing algorithm works within and between domains. |
| 2. | It need to know only about other routers within their domain. | It need to know only about other routers within and between their domain. |
| 3. | Protocols used in intradomain routing are known as Interior-gateway protocols. | Protocols used in interdomain routing are known as Exterior-gateway protocols. |
| 4. | In this Routing, routing takes place within an autonomous network. | In this Routing, routing takes place between the autonomous networks. |
| 5. | Intradomain routing protocols ignores the internet outside the AS(autonomous system). | Interdomain routing protocol assumes that the internet contains the collection of interconnected AS(autonomous systems). |
| 6. | Some Popular Protocols of this routing are RIP(resource information protocol) and OSPF(open shortest path first). | Popular Protocols of this routing is BGP(Border Gateway Protocol) used to connect two or more AS(autonomous system). |
