What is the default routing update period for RIPv2?

1. 180 seconds

2. 30 seconds

3. 240 seconds

4. 15 seconds

The correct answer is: 30 seconds

The correct answer for the default routing update period for RIPv2 is that it is set to 30 seconds. In the Routing Information Protocol version 2 (RIPv2), updates to the routing table are sent every 30 seconds by default. This periodic update helps ensure that all routers participating in the RIP routing domain maintain a consistent view of the network topology by sharing routing information regularly. RIP uses a simple distance vector algorithm, which relies on periodic updates to propagate routing information throughout the network. By having a default update period of 30 seconds, RIPv2 strikes a balance between timely updates and network overhead, avoiding excessive bandwidth consumption that could occur if updates were sent more frequently. In the context of network performance, the 30-second interval allows for acknowledgment of changes or failures in the network, ensuring convergence and stability. However, it is important to note that while RIPv2 has a default update interval of 30 seconds, there are other configuration options that can be adjusted based on the needs of a specific network.
