DR - Designated Router

The DR is a function of a broadcast or NBMA (Non Broadcast Multiple Access) network which operates the OSPF (Open Shortest Path First) routing protocol. The DR has two functions, namely: Generation and transmission of Network LSA (Link State Advertisement) for the entire network, thus reducing the amount of routing traffic and Synchronization with all other routers on the network in order to ensure routing information is current and valid.
