How do you explain OSPF?
- The OSPF protocol is a link-state routing protocol, which means that the routers exchange topology information with their nearest neighbors.
- The main advantage of a link state routing protocol like OSPF is that the complete knowledge of topology allows routers to calculate routes that satisfy particular criteria.
What is OSPF also known AS?
Open Shortest Path First (OSPF) is classified as an Interior Gateway Protocol (IGP). This means that it distributes routing information between routers belonging to a single autonomous system (AS), a group of routers all using a common routing protocol.
Why we use OSPF?
OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP). It’s used to decision routing in the autonomous systems. It realizes the Link State Routing Protocol, belonging to IGP, so that it works in the internal system.
Which algorithm is used in OSPF?
shortest path first (SPF) algorithm
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.
Why we use OSPF in networking?
Routers connect networks using the Internet Protocol (IP), and OSPF (Open Shortest Path First) is a router protocol used to find the best path for packets as they pass through a set of connected networks.
What is the difference between OSPF and BGP?
BGP and OSPF are two of the most common routing protocols. While BGP excels with dynamic routing for large networks, OSPF offers more efficient path choice and convergence speed.
Is OSPF unicast or multicast?
Update destination address: OSPF uses multicast and unicast, rather than broadcast, for sending messages. The IPv4 multicast addresses used for OSPF are 224.0. 0.5 to send information to all OSPF routers and 224.0.
When should I use OSPF?
Network convergence is the speed at which a router can adjust the path used to a destination network if a network outage occurs. Because of its convergence speed and ability to choose paths based on network performance, OSPF is a better choice within corporate LANs and private data centers.
What is BGP vs OSPF?
The main difference between OSPF and BGP is that OSPF is an intra-domain routing protocol using link state routing, and the routing operation is performed inside an autonomous system while BGP is the inter-domain routing protocol that uses path vector routing, with the routing operations performed between two …
