Hello Zaman
A fundamental characteristic of Link State routing protocols is that every router constructs a map of the connectivity to the network that indicates which nodes are connected to which other nodes. This map is contained within the database. Based on this map, each router independently calculates the next best logical path from it to every possible destination on the network. These collections of best paths are then used to populate the routing table on the router.
If the database is not the same in all routers within an area, then there can be several negative consequences:
I hope this has been helpful!
