I have a network with 4 routers, in OSPF settings the priority of the 4 routers is equal to 1, and the network id for R1 = 1.1.1.1, R2= 2.2.2.2, R3=3.3.3.3 and R4=4.4.4.4
so I read and learned that the router with higher network id should be the DR, but in my case my R1 is the DR and R2 is BDR, can someone explain this to me please ? thanks
