There is a network of 4 routers in OSPF area 0, where the routers are in a "ring" topology. System is configured in a way that all connections between routers are made within /30 subnets. Therefore, there are 4 segments, each of them with separate DR and BDR elected. My question is:
Is such design a good choice and what are the advantages of such design (if there are any) vs. design where all routers in the same Area would also be in the same segment/subnet (and then we would have a single DR/BDR in within area)?
