What is the primary role of a Route Reflector in BGP?

The primary role of a Route Reflector in BGP (Border Gateway Protocol) is indeed to reduce the number of iBGP (internal BGP) sessions. In a traditional iBGP setup, every BGP router must establish a direct peer session with every other iBGP router within the same autonomous system, leading to a significant number of connections as the network scales. This can result in a complex and demanding configuration, especially in large networks with many routers.

By deploying a Route Reflector, you can simplify this architecture. The Route Reflector acts as a central point that can receive iBGP updates from multiple clients and then reflect those updates to other clients. This means that instead of having each router connected to every other router, a minimal number of connections is required, greatly reducing the number of sessions and simplifying configuration and management.

The other options do not accurately represent the purpose of a Route Reflector. For example, increasing network latency is not a function of Route Reflectors; they are designed to streamline the process. An elimination of the routing table does not occur, as routing tables remain essential for directing data traffic within and outside a network. While creating a loop-free topology is crucial in networking, Route Reflectors primarily focus on reducing
