A 192.168.0.0/16 network
The 192.168.4.0 network is not included in the RIP configuration of R2.
The main difference between RIPv1 and RIPv2 is classless routing. RIPv2 incorporates the addition of the network mask in the update to allow classless routing advertisements. This is extremely important for the flexibility needed to efficiently utilize network assignments for an ever-shrinking pool of IP addresses.There are other differences, as well. In RIPv2, the destination address for the updates is multicast, instead of broadcast, as in RIPv1. This reduces the burden on the network devices that do not need to listen to RIP updates. With broadcast, every device on the broadcast domain must at least open the IP packet and process the initial information to determine relevance. With multicast addressing, if a device needs that information, it will listen to that specific address. If it does not need the RIP information, it does not have to process the multicast address. The multicast address RIPv2 sends to is 224.0.0.9.Another addition to RIPv2 is authentication. Authentication is used to ensure that routes being distributed throughout the network are coming from authorized sources.

To disable automatic summarization in RIPv2, you can use the command no auto-summary in the router configuration mode. For EIGRP, the command is no auto-summary as well, which can be entered in the EIGRP configuration mode. This prevents the router from summarizing routes at network boundaries and ensures that specific subnets are advertised.
Subnet mask
RIPv2 and EIGRP
yes
RIPv2 sends subnetmasks in the routing table updates. RIPv1 does not, which causes it be class-full.
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.
