RIPv2 is the enhanced version of RIPv1 (Routing Information Protocol). It is a simple distance vector protocol, which you can use in small networks because it does not use much bandwidth and it has very little configuration and management time. RIPv2 is the optimal choice for small networks (RIPv2 is  part of the CCNA syllabus) rather than OSPF, IS-IS, and EIGRP. RIP is documented in RFC2453.RIP uses broadcast User Datagram Protocol (UDP), and you can use the following ACL in order to match RIP packets: Access-list 100 permit udp any eq 520 any eq 520 Unlike RIPv1, RIPv2 sends routes along with...

RIPv1 is the oldest version of RIP (Routing Information Protocol). It is a simple distance vector protocol, which you can use it on routers that do not support other routing protocols such as RIPv2, EIGRP, and OSPF (these protocols are part of the CCNA syllabus). RIPv1 sends routes without their subnet masks. It is the function of the router receiving the RIP route to set a subnet mask for it. In the coming paragraphs, we will discuss the process of sending RIPv1 updates. Before discussing how RIP sends updates, let us see how to calculate the major network IP address of a specific subnet IP address...
