Which protocol helps manage traffic flow within an organization’s internal network?

The Internal Border Gateway Protocol (iBGP) is designed to manage the flow of data traffic within an organization’s internal network. Unlike its counterpart, External BGP (eBGP), which deals with route exchange between different autonomous systems on the internet, iBGP is utilized within a single autonomous system. Its primary function is to facilitate effective route propagation between routers in the same organization, ensuring that each router has a consistent view of the network's topology. This consistency is vital for optimizing traffic flow, enabling the network to make informed routing decisions and efficiently manage data paths.

For instance, in a large enterprise network with multiple routers, iBGP helps ensure that if one router learns about a new path to a destination, that information is communicated to all other routers within the same autonomous system. This coordination helps prevent routing loops, reduces data congestion, and enhances the overall reliability and performance of the network.

In contrast to this protocol, options like Traffic Mirroring relate more to monitoring traffic rather than managing it, while the Domain Name System (DNS) serves the function of translating domain names into IP addresses, and Remote Desktop Protocol (RDP) is used for remote access to networked computers. None of these alternatives address the specific need for managing internal
