The correct answer is C. Route redistribution.
In networking, routing protocols are used to determine the best path for data to travel from one network to another. Different routing protocols use different metrics, or criteria, to determine the best path. For example, the Routing Information Protocol (RIP) uses hop count as a metric, while the Open Shortest Path First (OSPF) protocol uses bandwidth and cost as metrics.
When different routing protocols are used within the same router, it is necessary to share metrics between them to ensure that the best path is chosen for the data. Route redistribution is the process of sharing routes and metrics between different routing protocols. When a router receives a route from one routing protocol, it can redistribute that route into another protocol's routing table.
Route redistribution is important for maintaining connectivity between different networks, especially when those networks use different routing protocols. It allows a router to take advantage of the strengths of different protocols and choose the best path for the data.
Routing loops, routing tables, and dynamic routes are all important concepts in networking, but they are not directly related to sharing metrics between routing protocols within the same router.
A routing loop occurs when a packet is continuously routed between two or more routers in a network, without ever reaching its destination. Routing tables are used by routers to store information about the paths available to reach different networks. Dynamic routes are routes that are learned and updated automatically by a routing protocol.
In summary, route redistribution is necessary to share metrics between routing protocols within the same router and ensure that the best path is chosen for the data.
