Differences between InterDomain Routing and IntraDomain


As we know that Routing is the process of forwarding the information/data packets from source to the destination but the best route to send the packets is determined by the routing algorithm.

So on the basis of interaction of domains we can distinguish between both InterDomain and IntraDomain Routing protocols. Following are the important differences between InterDomain and IntraDomain Routing.

Sr. No.KeyInterDomain RoutingIntraDomain Routing
1DefinitionInterDomain Routing as name suggests is the protocol in which Routing algorithm works within and between domains.On other hand IntraDomain as name suggests is a protocol in which Routing algorithm works only within the domains.
2Information RequiredIn case of InterDomain the interaction is between different domains so information of components of other domains is also required.On other hand as IntraDomain Routing has to interact within the domain so only information of different components within the domain is required.
3Protocols UsedIn InterDomain Routing Interior-gateway protocols such as RIP(resource information protocol) and OSPF(open shortest path first) are being used.While On other Exterior-gateway protocols such as BGP(Border Gateway Protocol) are being get used in case of IntraDomain Routing.
4PrerequisiteFor InterDomain Routing internet within the domain and in domain with which the interaction is going on should be connected and available.On other hand for IntraDomain Routing internet within the domain should be connected and available during the transmission.
5Complex and DependentInterDomain Routing is more complex and more dependent as compared to that of IntraDomain Routing.On other hand as mentioned in above points the IntraDomain Routing is less complex and less interdependent as compared to that of InterDomain Routing.
