The OSPF protocol is one of the most complex routing protocols that can be deployed in modern networks. OSPF is an open-standard protocol, whereas EIGRP is not. OSPF is a classless routing protocol and this allows it to support VLSM. OSPF uses the Dijkstra SPF algorithm to select loop-free paths throughout the topology, while EIGRP uses DUAL. OSPF is designed to be very scalable because it is a hierarchical routing protocol, using the concept of “areas” to split the topology into smaller sections.
OSPF usually does not converge as fast as EIGRP but it does offer efficient updating . . .
