In the route entry 'R 10.10.30.0/24 [120/1] via 10.10.50.2, what does '00:00:14' indicate?

1. The interval to reach the next hop

2. The time the route has been in the table

3. The expected lifetime of the route

4. The priority of the route

The correct answer is: The time the route has been in the table

The notation '00:00:14' signifies the time duration that the route has been in the routing table. This is an important aspect of dynamic routing protocols, where routes can become stale or be replaced over time. Knowing how long a route has been in the table helps network administrators determine the reliability and recency of the route information. In this context, a longer time in the table might suggest that the information is stable, whereas a very short interval could indicate that the route just became available and might not yet be fully trusted. It's essential for monitoring network performance and ensuring optimal routing paths are maintained. While the other options may be related to routing, they do not accurately describe what '00:00:14' represents in this context. The interval to reach the next hop and the expected lifetime of the route imply time metrics but are not correct in this specific scenario. Additionally, the priority of the route refers to administrative distances or metrics used in route selection, which is separate from the timing aspect denoted here.
