Which problem could arise from use of a distance-vector routing protocol?

Routing loops are the most common problem when you're using a distance-vector routing protocol. Although they can occur with any dynamic routing protocol, distance-vector protocols are most susceptible due to how they converge routes. RIP is extremely compatible with all router implementations, and it is a light protocol; therefore, it is found on many different routers. RIP is a very simple protocol to configure compared to other dynamic routing protocols. RIP also supports the advertisement of a default route.
