RIPv2 messages are sent using which type of broadcast?

RIPv2 messages are sent using multicast addressing. Specifically, they are sent to the multicast address 224.0.0.9. This method allows RIPv2 routers to communicate with one another efficiently without needing to send updates to all devices on the network, as unicast would do, which targets a single specific device. Similarly, broadcasting is less efficient in larger networks because it sends updates to all devices regardless of whether they need it or not, which creates unnecessary network traffic.

Multicast targeting is particularly useful in scenarios where multiple routers need to listen for routing updates simultaneously while reducing the overall load on the network. By using multicast, RIPv2 ensures that only routers configured to participate in RIP will process the update messages, creating a more efficient routing protocol that conserves bandwidth and reduces congestion in the network.
