Re: Basic Doubts

Hi

Area 0 is used as a transit area, which takes your traffic and passes to
other areas
You call area 0 as transport-bridge (as a real bridge which carries traffic
from one area to other)

Inter area routing works, it will until you are in the same area, till the
border of your area, moment you want to communicate to other area you need a
transit area/perhaps the communicator in between that's AREA 0

For Down bit, you can refer
