It is best practice to choose a specific Interior gateway protocols (IGPs), rather than run several within the same network. This means we have to decide which protocol to use. The most common ones are Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF).
OSPF vs EIGRP vs RIP
RIP has scalability limitations so it is not typically used in production. As a result, IGP choice for most companies is either EIGRP or OSPF; from those two, OSPF is the more commonly used, since it supports large networks and has always been an open standard (unlike EIGRP which is recently open, but has limited support on non-Cisco equipment).
Although EIGRP can be simpler to implement and maintain, the wide compatibility of OSPF makes it a much more common choice.
