Question

in the ospf area network dr and bdr selection procedure occur

let there are 4 router in that n/w r1 have the higher priority

then r2 and r2 have higher priority then r3 and so on

like that

r1>r2>r3>r4

now as we know that selection of dr and bdr based upon the 
router priority so in this case r1 will be dr and r2 will be 
bdr
now my question is that if i am going to implement 5th 
router which have greater priority then r1 then will it become dr atomically

remember that i am not going change my 5 or 1st router property
answer that one please

Answer
# 2

no, r5 will not be dr automatically....... it will become dr only if both dr & bdr goes down...
as whn dr goes down the bdr r2 will become dr. & r5 wll become bdr.after dat whn r2 goes dwn r5 will become dr...
so to make r5 to act as dr. we need disable & thn enable both r1 & r2
