Final answer:
In networking, sending the entire routing table to all routers at scheduled intervals is known as routing table broadcast, typically used in distance-vector routing protocols like RIP.
Step-by-step explanation:
The process of sending the entire routing table to all routers at a scheduled time is known as routing table broadcast. This approach is commonly associated with distance-vector routing protocols, such as the Routing Information Protocol (RIP). In this method, each router sends out its entire routing table, which contains all the routes it knows, to every other router within the network. The transmission occurs at regular intervals, ensuring that all routers have up-to-date routing information and can determine the best paths for packet forwarding.
Routing table broadcast is less common in modern networks due to its inefficiency, as the continual sending of the full routing table can consume a significant amount of bandwidth and processing power, and can lead to slower convergence times in dynamic networks. More sophisticated routing protocols, like OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol), use different mechanisms to maintain routing tables efficiently.
