TOP 10 OSPF INTERVIEW QUESTIONS & ANSWERS PART 1
FAQ
What is OSPF open shortest path first?
Open Shortest Path First (OSPF) is a link-state routing protocol that was developed for IP networks and is based on the Shortest Path First (SPF) algorithm. OSPF is an Interior Gateway Protocol (IGP).
How do you explain OSPF in an interview?
OSPF stands for Open Shortest Path First. It is a link-state routing protocol that uses the Shortest Path First (SPF) algorithm to find the best path between the source and the destination router. It was developed by Internet Engineering Task Force (IETF). It was developed as an Interior Gateway Protocol (IGP).
How shortest path is calculated in OSPF?
OSPF routers rely on the cost to compute the shortest path through the network between themselves and a remote router or network destination. The shortest path computation is done using Dijkstra’s algorithm. This algorithm isn’t unique to OSPF.
Which algorithm does OSPF use to find the best path?
OSPF uses the shortest path first (SPF) algorithm to determine routes that should be added to the routing table. OSPF routers maintain a map of the internetwork called the link state database.
