Topology refers to the arrangement of various elements in a network, including nodes and connections.
Topology defines how devices are connected and communicate in a network
Common topologies include bus, star, ring, mesh, and hybrid
Each topology has its own advantages and disadvantages
Topology affects network performance, scalability, and fault tolerance
Routing is the process of selecting the best path for network traffic to reach its destination.
Routing involves determining the optimal path for data packets to travel from the source to the destination.
Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.
Routing protocols like OSPF and BGP are used to exchange routing information between routers.
Dynamic routing allow...
Routing is the process of determining the best path for data packets to travel from a source to a destination.
Routing involves analyzing network paths and selecting the most efficient route.
Routers use routing tables to make decisions on how to forward packets.
Dynamic routing protocols like OSPF and BGP help routers exchange routing information.
Examples of routing protocols include RIP, EIGRP, and IS-IS.

I applied via Recruitment Consulltant and was interviewed in Dec 2024. There was 1 interview round.
OSPF (Open Shortest Path First) is a routing protocol used to determine the best path for data packets in a network.
OSPF is a link-state routing protocol
It uses Dijkstra's algorithm to calculate the shortest path
OSPF routers exchange link-state advertisements (LSAs) to build a topology map
It supports VLSM (Variable Length Subnet Masking) and CIDR (Classless Inter-Domain Routing)
OSPF areas are used to divide large netwo
BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different autonomous systems on the internet.
BGP is used to make routing decisions based on network policies, path attributes, and network reachability.
It operates on TCP port 179 and uses TCP connections to exchange routing information.
BGP routers maintain a table of IP prefixes and their corresponding AS paths to determin...
Normal communication check
A loop is a sequence of instructions that is continually repeated until a certain condition is met. An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network.
A loop is used in programming to execute a block of code repeatedly until a specific condition is met.
There are different types of loops such as for loop, while loop, and do-while loop.
An IP address is us...

OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets in a network.
OSPF is a link-state routing protocol
It uses Dijkstra's algorithm to calculate the shortest path
OSPF routers exchange link-state advertisements (LSAs) to build a topology map
It supports VLSM (Variable Length Subnet Masking) and CIDR (Classless Inter-Domain Routing)
OSPF divides the network into areas to reduce
Private IP addresses ranges are reserved for use within private networks and are not routable on the internet.
Private IP address ranges include: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255
These ranges are defined in RFC 1918 and are commonly used in home, office, and enterprise networks
Private IP addresses allow multiple devices to share a single public IP address for in
