Re: minimum configure time of ospf hello packet intervals

Based on what i am hearing Rakesh is correct. When you specify the
dead-interval to be minimum, you are setting the dead-interval to 1
second, and the hello multiplier means how many hellos i will send
within the dead intrerval, if its set to 4, it means 4 hellos in one
second which means 250ms.
