RIPv1
RIPv1 is the original version of the RIP protocol. The RIPv1 protocol imposes some limitations
on the network design with regard to subnetting. When operating RIPv1, you must not configure
variable length subnetwork masks (VLMS). Each IP network must have a single mask, implying
that all subnetworks in a given IP network are of the same size. Also, when operating RIPv1,
you must not configure supernets. RIPv1 is defined in RFC 1058.
RIPv2
RIPv2 is a newer version of the RIP routing protocol. RIPv2 solves some of the problems
associated with RIPv1. The most important change in RIPv2 is the addition of a subnetwork
mask field which allows RIPv2 to support variable length subnetworks. RIPv2 also includes
an authentication mechanism similar to the one used in OSPF. RIPv2 is defined in RFC 2453.
