Hi Srinivas
Here I am trying you clear your douts about that-
1. We always used the loopback interface on Router to
make sure that inetrface is always up even in case of
hardware failure or line protocol down .
2. For Load balancing on two serial interface we used
loop back interafce .
3.When you are configuring BGP prtocol between
diffrent AS that time you need to make BGP PEER aur
peer connection between two routers so you need to
define your interface always UP and without this
loopback interface it is not possible.
4.Null interface always used in router to give a
static path for unwanted trrafic. its work like a
Balck hole .
So Srinivas you go through this point if you still
face any problem then let me know.
Bye
