How often does RIPv2 send out routing updates?

RIPv2 (Routing Information Protocol version 2) is a distance-vector routing protocol used for routing within an autonomous system. One of its key characteristics is the frequency at which it sends out routing updates. Routing updates in RIPv2 are sent out every 30 seconds.

This interval allows networks to maintain up-to-date routing information and ensures that any changes in network topology can be propagated without overwhelming the network with frequent updates. Sending updates too frequently could lead to high overhead and increased bandwidth consumption, while sending them too infrequently could result in stale routing information.

The choice indicating that RIPv2 sends updates every 30 seconds aligns with the standard behavior of the protocol and demonstrates an understanding of RIPv2's designed operational characteristics.
