What are the advantages of RIPv2 over RIPv1?

RIPv2 offers several advantages over RIPv1, primarily through support for Classless Inter-Domain Routing (CIDR), which allows for variable-length subnet masks (VLSM). This enables more efficient use of IP addresses and better management of routing tables. Additionally, RIPv2 includes support for multicast updates, reducing unnecessary load on network devices, and provides authentication features to enhance security by ensuring that only authorized routers can participate in the routing process.
