I am searching for details of Open Shortest Path First (OSPF) and want to know more related to this. Will you provide Recently Asked Interview Questions on OSPF so I can prepare?

Open Shortest Path First is abbreviated as OSPF,which is a router protocol. OPSF is used for major autonomous system networks which are in preference to the Routing Information Protocol.

OSPF is designated by the Internet Engineering Task Force (IETF) as one of several Interior Gateway Protocols (IGPs).

OPSF uses link state routing algo.

List of some OSPF Interview Questions & Answers

1 What do you mean by OSPF?
OSPF refers to Open Shortest Path First. It is an open average link-state routing protocol which works by utilizing Dijkstra's SPF algorithm to find the straight paths.

2 How can we change the router ID in the OSPF domain?
OSPF Router ID should not be misused after the OSPF method is started and the OSPF neighborships are recognized. If we change the OSPF Router ID, we need to either refill the IOS or use “#clear IP OSPF process authority for changed RID to take effect.

3 Name the key attributes of OSPF?
Some of them are:

Equal Cost Routes management: CEF Load corresponding
Protocol Type of OSPF: Link State
Transport: IP (Port89) submit to network walks website
Metric of OSPF: Cost (Bandwidth)
Standard: RFC2328 (OSPFv2), RFC2740 (OSPFv3/IPv6)

4 Name the steps required to change neighborships into adjacency?
Some of the steps required are:

State Request (LSR) packets, Link State, inform (LSU) packets.
Two-way announcement
Database Synchronization which means a switch of Database Description packets, Link
After Database synchronization is complete, the two Routers are measured as adjacent.

5 Describe the four routers types?
The four router types are:

Autonomous System Boundary Routers = An OSPF Router which advertises exterior routes into the OSPF Domain.
Internal Routers = An OSPF Router whose all interfaces belong to the same area.
Area Border Routers = An OSPF Router which has interfaces in more than one area
Backbone Routers = An OSPF Router which is inside the Router in Area 0

6 What are the characteristics of OSPF?
The characteristics of OSPF are:

OSPF utilize cost as its metric, which is computed based on the bandwidth of the link.
OSPF is a classless routing procedure that supports VLSM and CIDR.
OSPF routes have an organizational distance of 110.
It has no hop-count limit. It supports limitless Hop count.
It allows for the creation of areas and independent system.
