Description: The ‘Routing Loop’ is a problematic situation where a data packet is continuously routed through the same routers in a network, without reaching its final destination. This phenomenon can occur in routing protocols such as BGP (Border Gateway Protocol) and EIGRP (Enhanced Interior Gateway Routing Protocol). In a routing loop, the packet moves from one router to another, but never encounters a valid route to its destination, leading to inefficient use of network resources and increased latency. Routing loops can be caused by incorrect configurations, changes in network topology, or communication failures between routers. To mitigate this issue, routing protocols implement various techniques, such as the use of timers, loop detection, and the implementation of algorithms that prevent loop formation. Identifying and resolving routing loops is crucial for maintaining the stability and efficiency of networks, as they can lead to network congestion and packet loss, thus affecting the quality of service provided to end users.
