I have one question for OSPF DR/BDR election
Consider 3 routers all with the same default priority 1 but different RIDs
RTA = 1.1.1.1 RTB =2.2.2.2 RTC =3.3.3.3
All routers come up at the same time.
RTC - DR and RTB -BDR.
Now,another router D with router ID =4.4.4.4 comes up in the network,it won't participate in election unless the already elected DR/BDR goes down
Consider 2 scenarios:
Scenario 1:
DR (RTC) goes down.What will be DR/BDR?
Scenario 2:
BDR (RTB) goes down.What will be DR/BDR?
