, OSPF Open Shortest Path First; a link-state interior
gateway protocol used to dynamically learn routes
inside one autonomous system.
OSPFv2 The IPv4 version of OSPF; this is the main OSPF
version used for CCNA single-area OSPF
configuration.
OSPFv3 The IPv6-capable version of OSPF; know the
concept, but CCNA OSPF focus is mostly OSPFv2.
IGP Interior Gateway Protocol; a routing protocol used
inside one organization or autonomous system,
such as OSPF, EIGRP, or RIP.
Link-state routing protocol A routing protocol where routers build a topology
database of the network and calculate best paths
from that database.
OSPF algorithm OSPF uses Dijkstra's Shortest Path First algorithm to
calculate the best path to each destination.
SPF Shortest Path First; the algorithm OSPF uses to
calculate loop-free best paths.
OSPF metric OSPF uses cost as its metric.
OSPF best path The route with the lowest total OSPF cost to the
destination.
OSPF administrative distance 110 by default on Cisco routers.
