Question

What is Cidr & OSPF

Accepted Answer

CIDR (Classless Inter-Domain Routing) is a method for allocating IP addresses and OSPF (Open Shortest Path First) is a routing protocol used in computer networks.

CIDR is a method of IP addressing that allows for more efficient allocation of IP addresses by using variable-length subnet masks.
CIDR replaces the older classful addressing scheme (Class A, B, C, etc.)
OSPF is a link-state routing protocol that uses the Shortest Path First algorithm to calculate the best path to a destination.
OSPF routers exchange link-state advertisements (LSAs) to build a topology map of the network.
OSPF supports multiple areas within a network, allowing for scalability and efficient routing.
Example: CIDR notation - 192.168.1.0/24, OSPF routing protocol in a large enterprise network.
