Which OSPF database packet determines which router is in charge of the database synchronization and the transferring of LSA headers between the two systems?
Which OSPF database packet determines which router is in charge of the database synchronization and the transferring of LSA headers between the two systems?
The Database Description (DD) packet in OSPF (Open Shortest Path First) serves two main purposes: determining which router is in charge of the database synchronization and transferring the Link-State Advertisement (LSA) headers between the two systems. During the adjacency formation process, routers exchange DD packets to determine the master-slave relationship, which dictates the router responsible for database synchronization. Therefore, the correct answer is the Database Description packet.
should be B
Hello packet When several systems or routers that run OSPF have interfaces attached to a common network, the Hello protocol determines the designated router (DR) .
B is correct
Changing answer to C
https://ipwithease.com/ospf-packet-types/ At the time of adjacency is being initialized, these packets are exchanged. These packets describe topological database contents. The database may be described by using multiple packets. A poll-response procedure is used for the description of multiple packets usage. Among the routers, one is designated to be master, and the other a slave. The Database Description packets are sent by the slave after sending the Database Description packets by the master.
the Database Description (DD) packets serve two main purposes: 1. determinining which router is in charge of the database synchronization 2. tansferring the LSA headers between the two systems
