MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Flooding: Each router sends the information to every other router on the internetwork except its neighbors. This process is known as Flooding. Every router that receives the packet sends the copies to all its neighbors. Finally, each and every router receives a copy of the same information.

Detailed explanation-2: -LSAs are distributed throughout a defined area by the process of reliable flooding. When a router receives a new LSA in a Link State Update packet, it installs the LSA in its database and then forwards the packet on all its interfaces except the one on which the Update packet was received.

Detailed explanation-3: -Link State Update packets are OSPF packet type 4. These packets implement the flooding of link state advertisements. Each Link State Update packet carries a collection of link state advertisements one hop further from its origin.

Detailed explanation-4: -In a computer network, flooding occurs when a router uses a nonadaptive routing algorithm to send an incoming packet to every outgoing link except the node on which the packet arrived. Flooding is a way to distribute routing protocols updates quickly to every node in a large network.
