1. RIPv1: 

RIPv1 uses classful routing. The periodic routing updates do not carry subnet information, lacking support for variable length subnet masks (VLSM). This limitation makes it impossible to have different-sized subnets inside of the same network class. In other words, all subnets in a network class must have the same size. There is also no support for router authentication, making RIP vulnerable to various attacks. 

2. RIPv2: 

RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. 

Due to the deficiencies of RIPv1, RIP version 2 (RIPv2) was developed in 1993 and was equipped with the ability to support subnet information and supports Classless Inter-Domain Routing (CIDR)
