DR/BDR election happens per network segment (broadcast domain) not per Area. So for every Layer 3 point-to-point link (p-to-p) you’ll see that an election has taken place. You can avoid this election configuring both ends of the p-to-p connection with “ip ospf network point-to-point” under interface configuration mode. With the command in place there is no DR/BDR election and therefore no OSPF LSA type 2 network are generated. “Broadcast” network mode is the default which should be used only when there are 3 or more OSPF peers in the network segment (usually a VLAN)
I hope this helps.
